C. BTRIATISSIMA PiUbry. PL 57, figs. 73, 74, 75 ; pi. 20, fig. 7. 



I in perforate, depressed, solid, acutely carinated, about equally 

 convex above and below the keel. Covered with a brown cuticle 

 which is finely and regularly raised into narrow lamellce in the 

 direction of growth-lines, the intervals between the lamellse being 

 microscopically obliquely wrinkled. Unicolored above, except that 

 the earlier whorls are denuded of cuticle and dark purplish ; the 

 base having usually numerous darker concentric lines. 



The surface is lusterless, densely lamellose, the cuticular folds 

 beinfc close and acute. The upper surface has neither oblique 

 streaks nor spiral lines. Whorls 4f, nearly flat, the last slightly or 

 considerably descending in front. Aperture oblique, livid-whitish 

 inside ; peristome blackish-brown, narrowly expanded above, angled 

 at the periphery, narrowly reflexed below ; columella sloping, not 

 toothed. 



Alt. 18, greater diam. 33, lesser 30 mill. 



Zebu, Philippines. 



H. (Carocolla) zebuensis, var. e. tota fusca, BROD., P. Z. S. 1841,

This form differs from C. zebuensis in being unicolored above, and 

 having densely lamellose cuticle. 



C. PFEIFFEKI Semper. PI. 44, figs. 34, 35, 36, 37. 



Ira perforate, depressed or depressed-turbinate, bluntly angled at 

 the periphery, more convex above than below the angle ; dark 

 brown, having a whitish-buff hydrophanous epidermis, radiating 

 from the suture above, and cut by spiral dark lines, forming a wide 

 band just below the peripheral angle, and cut into interrupted nar- 

 row concentric bands on the base. 



Surface smooth, lightly striatulate. Whorls 4f , somewhat con- 

 vex, the last descending in front. Aperture oblique, livid-whitish 

 within; peristome brown, rather broadly expanded and reflexed ; 

 columella sloping, abruptly truncated or toothed below. 



Alt. 22, greater diam. 33, lesser 28 mill. 



Alt. 26, greater diam. 31, lesser 28 mill.
