 Cochlostyla (Axina) carbonaria SEMPER, Reis., p. 191. v. MOLL., 

 Landschn. Cebu, p. 237. 



Among typical examples, at Alegria and Malabuyoc, are found 

 some of a handsome red color, with fiery-red peristome, which v. 

 Mollendorff proposes to call deviation rubens.

Imperforate, solid, subglobose-depressed, the periphery very ob- 

 tusely angled. Blackish-brown obliquely streaked and spirally 

 lineolate with buff-white hydrophanous cuticle above, having a 

 broad white band just below the periphery, the base having many 

 concentric whitish lines and some radiating streaks. 



The surface is smooth, lightly striatulate. There is a row of dark 

 and light blotches along the suture, as in C. pfeifferi. Whorls 5s, 

 convex, closely coiled, the last a very little descending in front. 

 Aperture whitish-leaden within ; lip reflexed, blackish-brown ; col- 

 umella white, deeply inserted, its edge slightly convex, not toothed 

 at base. Alt. 22 J, greater diam. 29s, lesser 26 mill.

This species was originally described from specimens denuded of 

 their hydrophanous cuticle. The original figures, copied on my pi. 

 41, figs. 17-19, represent them in this condition. A more satisfac- 

 tory illustration is pi. 57, fig. 76. 



From C. pfeifferi it is constantly and readily distinguished by the 

 more narrowly revolving whorls seen from above, and the more 

 Mvollcii base, which is far more excavated at the axis than in C. 

 pfeifferi.
