The typical selectus is a shell smaller than the dimensions given 

 above, dotted above and below, and somewhat obscurely maculated 

 below the suture and at the periphery. Z. articulatus of Reeve is this 

 form. The T. cunninghami is a much larger shell when fully 

 developed, and has no color markings beneath. When not fully 

 developed it is very broad and fiat beneath. These forms seem to 

 belong to a single sj^ecies ; I cannot separate the shells before me or 

 the published figures into two series ; there are too many intermediate 

 forms. Tr. decarinatus of Perry is an unknown species, perhaps the 

 same as C. canaliculatum Mart., l)ut certainly not allied to T. cunning- 

 hami or selection. 



C. meyer[ Philippi. Vol. X, pi. 41, fig. 35. 



Shell strictly conical, carinated, imperforate, thin but rather solid, 

 very pale yellowish or pinkish, with irregular, rather pale vertical 

 bands of light yellowish-brown, often broken into maculations, and 

 radiating on the base. The surface is shining, with numerous spiral 

 granose lirre, 7 in number on the penultimate, the antepenultimate, 

 and the upper surface of the last whoi'l ; and sometimes these three 

 whorls (or the last one) show interstitial threads between the granose 

 lirse; the flat base has 12 or 13 concentric lirse, the several inner 

 ones stronger, decidedly beaded, the 3 or 4 outer more separated, less 

 beaded ; the angular periphery is formed of a double beaded ridge, 

 and on some specimens this projects a little at the sutures of the 

 spire. The spire is conic, elevated, with straight lateral outlines ; 

 Avhorls 9 ; apex subacute, smooth ; the two earlier whorls following 

 the apical are tri-lirate ; the last whorl is angular at j^eriphery, flat 

 beneath, indented in the center around the insertion of the columella. 

 Aperture rhomboidal, oblique, angled on the outer part, above the 

 angle thickened inside by a heavy callous or pearly suhmarginal deposit; 

 columella oblique, arcuate, a trifle toothed at base.
