 dulis irregulariter sparsd, anfractibus plano-convexis, 

 indivisis, sitlcis liuearibus pertusis, auatuor ad sex, eequi- 

 distantibus cingulutis ; aperturd parvd, columella brevi, 

 recta. 



The cinctured Terebra. Shell somewhat cylindrically 

 turreted, rather solid, white, irregularly sprinkled 

 with a few, scarce, yellowish streaks, whorls flatly 

 convex, undivided, encircled with four to six equidis-

Mitre. The whorls, which are not divided at the upper 



part, are encircled throughout at regular distances with 



narrow, deeply excavated, linear, pricked grooves.
