COCHLOSTYLA-ORTHOSTYLUS. 



Bid. cunctator REEVE, Conch. Icon. f. 554, 1849. 



This form is closely allied to C. daphnis, differing in being 

 slightly less conoidal, and in the pattern of cuticle. It is likely 

 that intermediate forms will be found. Keeve's figure was drawn 

 from an immature example. 



C. FAUNUS Broderip. PI. 61, figs. 17, 18, 19. 



Imperforate, ovate-conoid, solid. Ground-color varying from 

 dark chestnut to light yellow-brown, the darker specimens becoming 

 lighter above the periphery and on the spire ; apical whorls purplish. 

 Covered with a light brown hydrophanous cuticle, which is either 

 almost uniform, or obliquely streaked having few or many darker 

 spiral lines. 



Spire conoid, apex decidedly obtuse. Whorls 6, the last slightly 

 descending. Aperture quite oblique; peristome narrowly reflexed, 

 having a black-brown edge. Columella vertical, nearly straight, 

 flesh-tinted.

Less variegated than C. daphnis, narrower in form, the spire not 

 so conical as that of C. daphnis, and not so acute. 



Both Semper and Mollendorff believe faunus to be a variety of 

 daphnis, but the differences of contour are so constant throughout 

 the large suites of each' before me, that I am still inclined to con- 

 sider them distinct species. There is a common form of C. daphnis 

 having the cuticle uniform, not variegated. A specimen of this 

 from Zebu is shown on pi. 42, fig. 21. 



C. TICAONICA Broderip. PI. 62, figs. 25, 26, 27, 28. 



Imperforate, ovate, solid. Ground-color dark chestnut, becoming 

 lighter on the spire, the earlier whorls light brown or purple-brown. 

 Hydrophanous cuticle white above, tinted with brown below, dis- 

 posed in wide or narrow oblique streaks, uninterrupted or cut by 

 dark spiral lines.
