Reeve's figure alleged to be eiliaris seems to be different. The 

 specimen described and figured by Philippi was sent to him by 

 Meuke. The whorls, according to Philippi, are flat, finely plicate 

 on their upper margins, margined on the lower, grooved with about 

 7 impressed transverse lines, the interspaces, cut by the stripe of 

 growth, here and there appear as if flatly grained. The upper whorls 

 have separated knobs on the margins ; the margin of the last whorl is 

 acutely angular, the base flat, a little excavated in the center, with 

 concentric impressed lines, becoming closer toward the periphery.

C. CASTKA Reeve. PI. 16, fig. 4. 



Shell broadly conoid, depressed, sharp-angled, rather thin, whorls 

 flatly sloping, spirally linearly engraved, obliquely plicately cren- 

 ulated below the sutures, corded at the basal margin ; pale flesh- 

 color, obscurely tessellated and reticulated. (Reeve.) 



Chiefly remarkable for its light, broadly depressed form and 

 almost total absence of sculpture. {Reeve.)

Shell erectly conical, pyramidal, the last whorl acutely angled at

 lirte, with little granules, two in the vicinity of the suture larger, 

 decorated with larger grains ; yellow, ornamented with jDurplish- 

 brown flames at the periphery, obscurely punctulate ; lirse of base 

 nearly smooth, dotted, base plane, subconvex; columella callous, 

 fauces smoothly striate. Alt. 40, diam. 36 mill. {MelvlU.)
