Distinguished from T. candei by the weakness of the columellar 

 fold and the spiral striation ; from hullata by its small size. 



T. cANALicuLATA Say. PI. 22, fig. 23 ; pi. 50, fig. 25, 26. 



Shell small, cylindrical, with low, conoidal terraced spire and 

 mamillar, strongly projecting minute apex. Ivory-white, with very 

 delicate growth-lines but no other sculpture. Whorls separated by 

 a channelled suture, concave-topped and more or less keeled at the 

 shoulder ; the last whorl cylindrical, tapering below. Aperture 

 about eight-tenths the shell's length, narrow above, broadly rounded 

 below, the outer lip thin, arched forward, retracted below ; colum- 

 ella thickened, concave, with a strong spiral fold. Alt. 5*5, diam. 

 2'75 mill. (S. Carolina specimen). Alt. 4*2, diam. 2'] mill. (Massa-

This is a larger species than the West Indian T. candei, with 

 smaller nuclear shell. Plate 50, figs. 25, 26, represent New Bedford 

 specimens. Fig. 23 of pi. 22 was drawn from a Massachusetts speci- 

 men which had lost its apex, a common mutilation, even in living 

 shells. The apex is uptilted at an angle of 90°, as in T. candei, etc., 

 but it is much smaller than in that species, although the shell is
