brown, darker below, becoming yellowish above, the apex flesh- 

 tinted, or (3) base dark chestnut-brown, upper surface light buff- 

 brown, or (4) body-whorl black-brown, the spire either pale or be- 

 coming purple tow r ard the apex. Hydrophanous cuticle cream-white, 

 rarely almost uniform, generally conspicuously streaked obliquely or 

 cut by spiral dark bands, or both cut and streaked. 



The spire is very, distinctly conoidal and more acute than usual. 

 Whorls 63, the last' somewhat descending. Aperture quite oblique, 

 white or blue-white inside ; peristome well expanded, brown, edged 

 with black-brown. Columella vertical, simple and straight, flesh- 

 tinted or purple-pink.

This species is excessively variable in the ground-color as well as 

 in the pattern of cuticle. The latter, however, has no zones of 

 greater intensity or whiteness, such as C. lignaria shows below the 

 periphery. The spire is notably conoidal, the narrower specimens 

 of typical daphnis approaching in this respect, C. imperator, a species 

 quite different in the form of the columella.

Imperforate, ovate- conic, solid. Ground-color brownish olive- 

 green, becoming yellowish on the spire, the earlier whorls flesh-col-

 brownish below, disposed in very close, narrow, oblique stripes. A 

 few T narrow, inconspicuous darker spirals are visible. 



Spire conoidal, obtuse. Whorls 6. Aperture blue within ; peri- 

 stome narrowly expanded, edged with black-brown. Columella 

 purple-pink, straight above, gently arcuate below ; not in the least 

 truncated below.
