176 HELICID^. 



Shell narrowly umbiliccited, depressed-globose, pale corneous, 

 finely striated transversely, densely covered with hair-scars arranged 

 in quincunx ; spire depressed, apex obtuse, suture linear. Whorls 5, 

 convex, increasing rather rapidly, the last much dilated towards 

 the mouth and slightly constricted behind the peristome, the base 

 inflated towards the mouth, not augulated at the periphery or 

 around the umbilicus. Aperture broadly auriculate ; margins 

 slightly appi'oaching, united by a thin flexuous callus on the 

 parietal wall ; peristome wliite, thickened, and reflexed, upper 

 margin nearly straight, outer and basal curved, columellar ver- 

 tical, broadly triangularly dilated and reflexed over the narrow 

 umbilicus. 



Major diam. 30, minor 25, alt. 18"5 mm.; apert. width 13, 

 height 14 mm.

The species, although well illustrated in Conch. Ind., has never 

 been described. The above description is drawn up from the 

 shell — probably the type— in the Theobald collection in the 

 British Museum. 1 have adopted the later spelling of the specific 

 name, the earlier one in the J. A. S. B., in both cases, being 

 evidently due to a printer's error. 



This and the next species bear a striking resemblance to 

 C. franciscanorum, Gredler, a Chinese form.

Oriqincd description : — " Shell moderately umbilicated, depressed- 

 conoid, pale corneous, with a very faint supra-peripheral band, 

 finely striated transversely, and densely covered with hair-scars 

 arranged in quincunx. Spire conoid, apex prominent, suture 

 rather deep. Whorls oh, convex, increasing slowly and regularly, 

 the last widening towards the mouth, not constricted behind the 

 peristome, slightly angulated at the periphery at first, the angu- 

 lation disappearing near the mouth ; augulated around the deep 

 umbilicus, which shows nearly the whole of the penultimate whorl. 

 Aperture subcircular, margins distant, united by a thin sinuous 

 callus on the parietal wall ; peristome white, thickened and shortly 

 reflexed ; margins regularly curved, columellar ascending, trian- 

 gularly dilated, and slightly overhanging the umbilicus.

The shell on which this species is based occurred with the 

 specimen of C. anserina in the Theobald collection. It difi'ers 

 from the latter in having a more conical spire and a wider 

 umbilicus, the base is less inflated, and in consequence the aper- 

 ture is more dilated laterally. It is also differently coiled, for, 

 although it measures one-fifth less in its diameter, it possesses
