Fig. 133.—Loxonema Cotterana. 
Description.—Elongate, fusiform, acute, apical angle, between 25° 
and 30°; whorls four to six; very depressed convex; body whorl 
large, occupying full one-half the whole length of the shell, descend- 
ing with a uniform convexity into the aperture; aperture elongate 
ovate, effuse below, columellar lip extending about three-fourths of an 
inch below the body of the whorl. The suture in the cast deeply 
excavated, but narrow, the fissure descending into the fossil obliquely 
downward, the whorl below presenting a sharp edge over it, and the one 
above, an obtusely convex slope into it ; this is the appearance presented 
when the suture is completely cleared of the shell. Surface unknown. 
Length, three inches. Length of last whorl measured on a line 
passing longitudinally along the inner lip, one inch and a half; diam- 
eter of last whorl, one inch.
