 f T. vetusta Gregorio, Mou. Faun. Eoc. de l'Ala., pi. 1. figs. 40. 41. 



Specific characterization. — Size and general form as indicated in 

 the figure; whorls 12 or 13, longitudinally ribbed, the ribbing being 

 much coarser in the upper part of the shell than in the lower; suture 

 margined below by an obscurely impressed revolving line; columella 

 straight, smooth, tapering rapidly. 



This species is characterized at once by the height of its whorls in 

 comparison to their respective diameters, the bulging sides of the 

 whorls, the irregularities of the ribbing, and the straight, smooth 

 columella.

 Conus smithvillensis nov. sp. PL 4, fig. 2. 



Specific characterization. — General form as figured; whorls about 

 12; smaller spiral whorls costate or crenulate; penultimate whorl 

 smooth; body whorl smooth, except about 12 revolving lines at base. 



This species bears much resemblance to the figure given in Proc. 

 Ac. Nat. Sci. Phila., 1879, pi. 13, fig. 8, of "Conn*" pulcher- 

 rimus Heilp., but upon examining the type of this species now in the 

 Amer. Mus. Nat. Hist., N. Y. City, it was found to be, as already
