Ocean geography: Indo-Pacific
Type Locality: Pilas Island, Mindanao, Philippines
Type Data: MNHN deposited and catalogued
Type Size: 59.5 x 30.9 mm
Nomenclature: An available name
Taxonomy: A valid species or a form of Conus magus L., 1758
Current Group Names:-
Family:-CONIDAE SubFamily:-CONINAE
Genus:-Pionoconus Species:-quasimagus
Synonyms:-

Habitat:-At 45 m
Description:-Original description translated from Italian
Species of medium size for its genus; maximum size 78.6mm; solid; conical to ventricosely conical in shape; spire of moderate height with slightly concave outline; shoulder angulate; right side of whorl slightly more convex on holotype than paratype. Protoconch of two whorls but damaged; teleoconch with 6 concave whorls, deep suture and strongly margined; a strong spiral channel on whorl tops with 3 spiral threads with dense curving striae. Aperture narrow becoming wider at base.

Last whorl covered with minute spiral threads which become stronger near base. Some weak axial growth striations. Colour brownish yellow with two darker bands separate by a smaller band of light yellow patterned by the whorls spiral threads. Spire white with brownish yellow flammules on ramps. A light yellow line on edge of shoulder. Inside of aperture white.
Discussion:- The new species should be compared with several varieties of magus, especially C. m. raphanus. C. quasimagus differs from raphanus in the posterior part of aperture i.e. normal versus wide; the base colour of yellowish brown as opposed to white; in the spiral design of the last whorl which is homogenous in all C. magus forms.

Type Size: 25.7 x 12.7 mm
Nomenclature: An available name

Family:-CONIDAE SubFamily:-PUNCTICULIINAE

Synonyms:-

Geographic Range:-Natal, South Africa
Habitat:-Intertidal to 240 m
Description:-Source Iconography Summary
Moderately small to medium-sized shell (30 to 55 mm); conical shell, somewhat elongate, with straight sides and a undu1ate or weakly tuberculate shoulder. Spire low, dome-shaped with irregular raised whorls. Protoconch mamillate. The ear1y sutural ramps are beaded, whereas the late sutural ramps are smooth. There are regular low and close sets of spiral cords covering the body whorl. Ground color ivory-white. Pattern consisting of pale brown broad spira1 bands at the located mid-body and on the basal half, overlaid with more or less dense brown flecks and white bars arranged in spiral lines. Columella purplish brown. Aperture white or very pale bluish-white with faint brown at the base.
Discussion:-In a recent article published in the digital magazine The Cone Collector, Filmer (2008) has reviewed and commented upon the status of this taxon and mentioned the fact that the illustration published in the Annals of the Natal Museum does not correspond to the existing deteriorated holotype, but possibly to an artistic interpretation of the fresh shell. The relationship of Conus queketti to Conus imperialis is evident from both the original description and illustration and the study of the holotype. However, these South African imperialis-like shells that are referred to as C. queketti are scarce and usually found in poor condition, although live-taken specimens are known. This has in fact prevented a thorough investigation that would clarify the issue once and for all. The smaller size associated to C. queketti when compared to C. imperialis comes from the fact that most of the scarce material available corresponds to juvenile shells. Adult shells are significantly smaller than C. imperialis in any of its forms. Given the constant differences in size, pattern and conchological features, and the fact that the Natal populations are geographically isolated, it is considered as a subspecies of C. imperialis.

Geographic Range:-Indo-W. Pacific
Habitat:-Subtidal, to more than 70 m, rarely and probably only seasonally entering the lower intertidal zone. A sand-dweller throughout its entire range, living in bays on vast flats of sand, often found among vegetation but avoiding habitats with rocks and coral or limestone outcrops.
Description:-Source Living Conidae
Moderately large to large, moderately heavy to heavy. Last whorl conical to broadly conical, sometimes ventricosely conical to broadly and ventricosely conical; outline convex adapically, becoming straight below. Shoulder angulate to rounded. Spire of low to moderate height, outline concave. Teleoconch sutural ramps flat, with 2 increasing to 7-12 spiral grooves; spiral sculpture obsolete in some specimens. Last whorl with variably spaced spiral ribs on basal third.
Ground colour varies from white (in forms akabensis and albus) to various shades of yellowish brown in most shells. Last whorl usually with pale to pronounced, fine brown spiral lines, either numerous and closely set or sparse and more widely spaced; lines often obsolete in large specimens, sometimes absent from all post-larval stages. Larval and adjacent postnuclear spire whorls brown. Aperture white.

Discussion:-Based on the absence of spiral grooves on its sutural ramps and its golden brown periostracum, Coomans et al. (1979) regard C. albonerosa as a separate species. However, C. quercinus shells may have obsolete spiral sculpture on the sutural ramps (India), a golden brown periostracum (Indian Ocean) and an immaculate white colouration (forms akabensis and albus). These observations suggest the synonymy of C. albonerosa and C. quercinus.
C. q, akabensis from Red Sea, retain high spire and slender body and are completely white without pattern;
C. albonerosa white shells from Queensland,Solomons, New Guinea missing spiral grooves on whorls.
C. albus, invalid homonym, wide shaped white specimen from Aden.
C. cingulum is corded specimen

Type Locality: Balabac Is., Palawan
Type Data: Holotype in LACM deposited and catalogued
Type Size: 79.3 x 44.5 mm
Nomenclature: An available name
Taxonomy: According to Filmer a synonym form of Conus quercinus [Lightfoot], 1786
Current Group Names:-
Family:-CONIDAE SubFamily:-PUNCTICULIINAE
Genus:-Calamiconus Species:-quercinus jeffreyi forma
Synonyms:- There are no junior synonyms
Geographic Range:-Palawan, Philippines
Habitat:-No Data
Description:-Source Original description
Shell large for genus, subpyriforrn, broad across shoulder, heavy and thickened; shell profile with straight sides; spire low and flattened, with only early whorls projecting above plane of spire; shell widest below (anterior of) shoulder. Body whorl shiny, with silky texture, ornamented with extremely numerous, closely-packed fine spiral threads; anterior one-third of shell sculptured with 20-30 large, strong spiral cords; base color varying from lemon-yellow (as in holotype) to golden-yellow, overlaid with 2-3 wide bands of darker yellow or golden-yellow; some individuals marked with fine, dark golden-tan spiral lines, often arranged in two bands; anterior tip darker yellow or golden-tan. Spire whorls flat and planar, with early whorls slightly elevated and subpyramidal; whorls ornamented with 6 large spiral cords and finer spiral threads between each pair of large cords; color varying from pale yellow (as in holotype) to golden-yellow; early whorls pale brown. Shoulder sharply-angled, edged by large, rounded carina; sub-sutural area flattened. Aperture uniformly, wide slightly flaring toward anterior end; interior pure white.
Discussion:-Calamiconus jeffreyi n. sp. is most similar to the common, widespread shallow water Indo-Pacific C. quercinus (Lightfoot, 1786), but differs in being a larger, more elongated and pyriform shell, in having a rougher- textured shell with stronger spiral threads, and in being a much less colorful shell, most often lacking dark brown spiral lines. Some rare golden-tan specimens of C. jeffreyi n. sp. from Balabac Island exhibit fine brown spiral lines similar to those found on C. quercinus, but these color lines differ in being proportionally thicker and more densely-packed.
