COCHLOSTYLA-ORTHOSTYLUS. I 



This species is allied to C. mus, but differs notably in being 

 narrower, with longer spire and smaller aperture. The style 

 of coloring reminds one of C. fenestrata and C. curia (p. 

 192 of the preceding volume), and its true systematic position is 

 still an open question with me. See also Semper's remarks upon 

 this species. C. leucophcea differs from all forms of C. metajormis 

 and rustica in the dark-edged lip. 



C. GLAUCOPHTHALMA Pfeiffer. PI. 1, fig. 3. 



Shell imperforate, ovate-oblong, solid, striafulate ; black-chestnut 

 with a streaked brown-ashen hydrophanous cuticle. Spire convex- 

 conoid, the apex dark blue, obtuse ; suture impressed ; whorls 5, a 

 little convex, the last shorter than the spire, obsoletely an gu la ted at 

 the base. Columella somewhat sloping, dilated, flat, white, some- 

 what toothed at the base. Aperture oblique, truncate-oval, livid 

 inside ; peristome simple, very slightly expanded, the right margin 

 bowed. (Pfr.) 



Alt. 36, di.am. 25 mill. ; aperture, alt. 19, width 14.

I have not seen this species. It seems to be allied to C. mus and 

 leucophcea in contour, and to C. satyrus var. cyanocephala in color 

 pattern. 



C. SECKENDORFFIANA Pfeiffer. Vol. VII, pi. 37, fig. 49. 



Imperforate, turbinate, solid, somewhat glabrous, shining, chest- 

 nut-tawny. Spire elevated, apex obtuse, blue. Whorls 5, convex, 

 the last ventricose, not descending in front, the base chestnut-black- 

 ish. Columella oblique, wide, white, the base subdentate. Aper- 

 ture rounded-subtetragonal, whitish inside ; peristome subexpanded, 

 brown-edged, the basal margin narrowly reflexed, forming an angle 

 with the columella. Alt. 32, greater diam. 34, lesser 29 mill.

This species may belong to the section Calocochlea, in the neigh- 

 borhood of C. dimera, etc. It is known to me by the description 

 and figures only.
