96 COCHLOSTYLA-CHLOR^EA. 



In the typical C. hanleyi (pi. 22, figs. 24-26) the whorl is very 

 deeply deflexed in front, the suture and carina are bordered below 

 with white. There are no other bands on the pale greenish-yellow 

 ground-color. 



Color var. (pi. 22, figs, 27, 28). Blackish-purple above, banded 

 with white at suture and carina ; base buff-white, having a rufous 

 band below the carina. Form as in the type. 



Var. HUGELI Pfr. PI. 22, figs. 15, 18, 19, 20. 



Slightly larger than typical hanleyi, less acutely carinated, the 

 aperture less oblique and larger. Color greenish-buff with a white 

 girdle at periphery, bordered above and below by narrow green 

 bands. Alt. 12, diam. 18 mill.

The name proposed for this species by Lea in 1841, is not pre- 

 occupied in Cochlostyla, and it should probably be adopted. 



A variation of this form (pi. 22, fig. 15) has three narrow brown 

 bands ; one below, another above the periphery, and the third closely 

 bordering the suture below. The basal band is sometimes lacking 

 in this color-variety. Pfeiffer's figs. 11, 12, of pi. 69, Conchyl. Cab., 

 represent this form. 



Hidalgo believes that Pfeiffer confused two forms under the name 

 Hugeli; and considers the figures 10 and 14 to represent the true 

 hugeli, of which he considers Semper's C. antonii a synonym. In 

 this view I am unable to concur. Pfeiffer's fig. 10 is reproduced on 

 my pi. 22, fig. 20. 



C. BENGUETENSIS Semper. PI. 21, figs. 23, 24, 25. 



Imperforate, lenticular, thin, acutely carinated, obliquely striat- 

 ulate, whitish ornamented with a buff band above the carina and a 

 chestnut line at the suture ; spire little elevated ; whorls 4, rather 

 flattened, the last deflexed and constricted in front. Aperture large, 

 subhorizontal, angular-elliptical ; peristome simple, margins remote, 

 the upper margin slightly expanded, basal margin reflexed.
