ANOMA. 13 



rather narrow truncation ; rather solid, cream- white, profusely 

 striped with brown or corneous-brown, squarish or wedge- 

 shaped stripes. Surface glossy, finely and faintly striate, 

 the striae becoming stronger, rib-like and arcuate on the back 

 of the last whorl. Whorls 7% to 8 remaining, slightly con- 

 vex, the last strongly carinate beneath, the keel cream- white; 

 having a black-brown stripe behind the white lip, and a black- 

 brown area on the base, both showing also within the aperture. 

 Aperture usually subvertical, the outer lip but slightly sin- 

 uous, Avell expanded, white; columellar lip well dilated, 

 hardly notched above; terminations of the lip approaching, 

 connected by a short, transparent- white parietal callous. Col- 

 umella not noticeably truncate in an oblique view. Axis 

 straight, vertical, and rather stout in the last whorl, sinuous 

 in the penult., above which it is slender and straight. 



Length 20-21, diam. 6 mm.

Easily distinguished from species of the splendens group 

 by the longer basal keel, different form of the aperture and 

 lip, and the particular color-pattern, which seems to be very 

 constant. C. zebrina Pfr. (pi. 17, f. 1, 2, copies of orig. figs.) 

 applies to exactly the same form as tesselata.

" Shell of medium size and form. Pale ash color, black at 

 the summit, with transverse broad umber stripes, which are

 and pale on the middle whorls, and obsolete on the last whorl, 

 with a dark brown line along the suture and another on the 

 anterior keel. Lip white, with a black stripe behind it on the 

 right, and a black spot behind on the left. Back of the last
