HELIX. 33 



H. NEHERENSIS, Benson. PL 7, figs. 80, 81. 



Narrowly, perspectively umbilicated, obliquely striulate, de- 

 cussated above and below by very close scarcely impressed con- 

 centric lines, suture subchanneled ; whorls 5, a little convex, 

 the last rounded at the periphery, convex below, excavated 

 around the umbilicus ; margins of peristome joined by a thin, 

 minutely granulated callus. Diam. 5 mill. 



Mahabaleshwar, Western India. 



The figures, which are copied from Conch. Indica, appear to 

 represent a Hyalina rather than a Patula. Perhaps the striae 

 are not sufficiently indicated. 



H. ARTIFICIOSA, Benson. PL f, fig. 82. 



Narrowly umbilicated, a little shining, above with close revolv- 

 ing lirae and sulcations, decussated by oblique costulations, below 

 with remoter lirie and radiating striae, light corneous, suture 

 deep; whorls 6^, a little convex, slowly increasing, the last sub- 

 angulate above, convex below ; peristome slightly sinuated, right 

 margin crenulate. Diam. 14 mill. 



Tenasserim, Burmah. 



Does not belong in this group. 



H. FRITILLATA, Benson. PL 22, figs. 17-19. 



Perspectively umbilicated, arcuately costulate-striate, decus- 

 sated by impressed close spiral striae above, the interstices con- 

 spicuously quadrately granular, smoother and polished below, 

 light corneous, suture profound ; whorls 6, narrow, slowly enlarg- 

 ing, convex, the last scarcely descending anteriorly, more convex 

 below, and excavated around the umbilicus ; peristome externally 

 margined below, extremities remote. Diam. 13 mill. 



Pegu. 

 H QUADRISPIRA, Martens. PL t, figs. 83-85. 



Widely perspectively umbilicated, subangulate, closely some- 

 what obliquely costulate, grayish white, a little shining ; whorls 

 4, slightly convex ; rapidly increasing, with deep suture, last 

 whorl subangulated, descending in front, more convex below ; 

 margins of peristome approaching. Diam. 5'5 mill.
