140 COCHLOSTYLA-OALOCOCHLEA. 



Hydrophanous cuticle disposed in dose narrow bands and lines, 

 closely interrupted by the wrinkles of growth. Earlier whorls whitish. 



Spire convex-subconoid, obtuse ; whorls 4|, the last slowly and 

 slightly descending. Aperture large, oblique, white or nearly so in- 

 side ; peristome broadly reflexed, rather thick, its face and reverse 

 white. Columella wide, heavy, oblique, white. 



Alt. 38, greater diam. 41, lesser 33 mill. 



Alt. 31, greater diam. 32 mill. 



Philippines. 



This species is allied to C. polillensis and C. codonensis. It is a 

 distinctly solider shell than the first, with a much broader lip and 

 heavier columella. It is less elevated than C. codonensis, with an 

 entirely different color-pattern, the lip not black-edged, the columella 

 not roseate, etc. 



C. CODONENSIS Hidalgo. PL 53, fig. 37. 



Imperforate, subglobose, solid, obsoletely sculptured with wrinkles 

 of growth : shining and tawny, with a black columellar band, under 

 an opaque white more or less interrupted or broadly streaked 

 hydrophanous cuticle. 



Spire obtuse, whitish or rosy ; whorls 4J to 5, a little convex, 

 rather rapidly widening, the last large, very convex, obliquely some- 

 what descending in front ; columella long, suboblique, rather flat, 

 rose colored, the callus becoming outwardly bluish-white. Aperture 

 ample, oblique, lunate-oval ; peristome widely expanded and re- 

 flexed ; its inner part, with the aperture, whitish-blue, its outer edge 

 intense black. (Hid.)

This species is allied to C. polillensis and its varieties, but the 

 aperture is relatively higher, the columella roseate and straighter, 

 the peristome more reflexed, and black on the outside ; the epidermis 

 has a different aspect and the last whorl is more oblique, etc. (Hid.')

Imperforate, rather thin, globose-depressed or subglobose ; surface 

 nearly smooth, the growth-lines light, the earlier whorls seen to be 

 spirally striate under a lens. Straw-yellow, with irregular oblique
