This is a larger species then C. hanleyi, and the whorl is less de- 

 flexed in front. Some forms of C. hugeli approach it, but they are 

 less acutely keeled behind the lip, and differ in coloring. Hidalgo 

 describes the following color-varieties : 



1. Whitish or whitish-yellow, unifasciate above and below. 



2. No band beneath. 



3. Smaller; white, not banded. From Marinduque (pi. 21, fig. 

 33.) 



4. Chestnut colored above, with a white peripheral band continu- 

 ing up the spire above the suture; base 4-zoued, the two columellar 

 zones tawny, outer paler, the third zone chestnut, the peripheral zone 

 white (pi. 21, figs. 31, 32.) 



5. Buff, not banded below. Island of Lubang. 



C. HANLEYI Pfeiffer. PI. 22, figs. 24, 25, 26, 27, 28. 



Imperforate, depressed, solid, acutely carinated; light greenish- 

 yelloiv, a band at the carina and a border below the suture opaque 

 white. Last whorl very deeply deflexed in front, the aperture nearly 

 horizontal. 



The shell is about equally convex above and below; surface 

 microscopically striate spirally. Whorls 4, flat, the entire circum- 

 ference of the last whorl acutely carinated. Aperture small, oval, 

 subhorizontal ; the peristome white, reflexed, its terminations 

 approaching. Alt. 9, diam. 17 mill.
