COCHLOSTYLA-EUDOXUS. 37 



This species varies greatly in degree of elongation, but the 

 extremes seem to be closely connected by intermediate variations. 

 Figs. 39, 40, represent the chloroleuca Mts., a shell almost exactly 

 like Lea's type of virginea. 



Fig. 68, pi. 9 represents the form named BUSTOI by Hidalgo, 

 and which is said by him to be a distinct species, distinguished by 

 the more conoidal shell, spire having an additional whorl and tipped 

 with reddish ; last whorl more transverse, less high ; aperture 

 oblique, peristome more reflexed. These differences do not seem to 

 be always associated, in the suite of 18 specimens before me. The 

 C. bustoi is from Catanduanes Is. 



In regard to the name adopted for this species, it must be said 

 that Lea's description is fully as good as Broderip's, and has indis- 

 putable priority of publication. Broderip's description was not 

 actually printed, I believe, until 1841. I have examined Lea's type 

 specimen of B. virgineus. European conchologists do not seem to 

 be aware of Lea's paper in the Proceedings of the Philosophical 

 Society, as they quote the Transactions only. 



C. HOLOLEUCA Pfeiffer. Unfigured. 



Imperforate, conic-ovate, rather thin ; striatulate, shining, sub- 

 diaphanous, white. Spire convex-conic, obtuse; suture narrowly 

 margined; whorls 5, slightly convex, the last rather rounded ; col- 

 umella straightened, scarcely oblique, callous ; aperture oblique, 

 truncate-oval, concolored within ; peristome narrowly expanded, 

 the columellar margin dilated, adnate, forming a distinct angle with 

 the basal margin. (Pfr.} 



Alt. 32, diam. 23 ; aperture, alt. 15, width 12 mill.

C. SMARAGDINA Reeve. PL 2, figs. 19, 20, 21, 22. 



Imperforate, oblong-conoid, smooth and shining ; solid ; color 

 varying from bright green to yellow, olive or brown, rarely banded ; 

 the earlier whorls either white or purple-brown ; suture always hav- 

 ing a white border below. 



The spire is conoid, elevated, rather acute ; whorls 51 to 6. 

 Aperture oblique, white or purplish within ; peristome expanded and
