32 COCHLOSTYLA-EUDOXUS. 



I cannot believe that the shell figured in Philippi's Abbildungen, 

 Bui. pi. 6, fig. 8, is this species. The columella is entirely different 

 in form. 

 C. HALICHLORA Semper. Vol. VII, pi. 27, figs. 4, 5. 



Imperforate, globose-turbinate, thin but solid, of a delicate light 

 green tint, becoming white on the spire. Surface shining, smooth, 

 delicately obliquely striatulate and having some obsolete, micro- 

 scope spiral lines. Spire elevated, apex obtuse, often tipped with 

 orange; whorls 5, slowly increasing, the last rounded or obtusely 

 angied at the periphery, scarcely descending in front. Aperture 

 large, oblique, subrhombic, white within ; penstome narrowly 

 expanded, its edge often slightly tinged with rust-color ; columella 

 vertical, white, straight, its face flattened, deeply inserted.

Cochlostyla (Corasia) halichlora O. SEMPER, Journ. de Conchyl. 

 1866, p. 263, t. 8, f. 1. SEMPER, Reis. Phil, iii, p. 172. 



This globose-turbinate, light green-tinted shell is typically very 

 distinct from other known species, but I have seen specimens inter- 

 mediate between halichlora and effusa. Semper considered this 

 species a Corasia, but it is undoubtedly an Eudoxus. 



C. LEAI Pfeiffer. PL 17, figs. 33, 34. 



Imperforate, ovate-conoid, rather thin, shining; light buff. 



Spire conoidal, apex obtuse ; whorls 5*. somewhat convex, the 

 last obtusely subangulated in front. Aperture shorter than the 

 spire, oblique, rounded-quadrate; peristome narrowly expanded, 

 thickened within ; columella distinctly flattened, steeply sloping.

 Conch. Icon. t. 12, f. 66. 



The shell described above and represented in fig. 33 differs from 

 Pfeiffer's description in being bluntly angled at the periphery. I 

 believe, however, that it is the C. leai. 



C. JONASI Pfeiffer. PL 8, figs. 53, 54, 56, 57 ; pi. 17, fig. 32 ; Vol. 



VII, pi. 37, figs. 43, 44. 



Imperforate, ovate-conoid, rather solid, smooth, of a light yellow 

 tint, which is either clear buff or verging toward green or tawny.
