CANTHAIIUS. 159 







by rather coarse, unequal, spiral 'striae, with the intersections of 

 the larger stria? rather acutely nodulous ; apex acute ; spire conic ; 

 whorls eight, very convex, with a moderately impressed suture ; 

 aperture ovate ; labrum rather sharp, thickened behind ; with a 

 short, recurved canal. Length, -67 inch. 



Panama and Taboga ; under stones at low water. 



I am not acquainted with this species. 



C. ELATA, P. P, Carpenter. 



Shell elate, white, strigate or maculate with reddish brown ; 

 whorls more than six, convex, with impressed sutures ; longitu- 

 dinal ribs six to eight, crossed by alternately larger and smaller 

 revolving lirulre ; canal narrow, subrecurved ; aperture subovate, 

 dentate within. Length, '68 inch. 



Cape St. Lucas, L. California. 



The description indicates imperfect specimens. I have before 

 me a shell received from the Smithsonian Institution as from 

 Cape St. Lucas, and identified. by Carpenter as C. lugubris, C. B. 

 Ad. This shell corresponds so well with the above description 

 that I suppose it to be the same ; but it is in too imperfect condi- 

 tion to figure advantageously. 



C. PUNCTICULATUS, Dunker. 



Shell small, ovately acute, more or less graceful, subfusiform, 

 transversely lirate, lirse crowded, longitudinally costate, costa3 

 granose. Whitish or yellowish, the nodules obscurely fuscous. 



Length, 10-15 mill. 



Red Sea. 



I am not acquainted with this species Mr. Tapparone-Canefri 

 suspects that Buccinum seriale, Deshayes, will prove to be iden- 

 tical with it, in which case the latter name will have priority. It 

 is said to resemble B uc. Scacchianum (= pictus, Scacchi). 



C. PAPUANUS, Tapparone-Canefri. 



Small, ovate-fusiform, attenuate above and below, graceful. 

 Color white and light brown, with darker spots upon the spiral 

 lines. Spire subturretted, apex smooth. Whorls eight, more or 

 less angulate above, the three upper ones smooth, the rest spirally 

 lirate and obscurely longitudinally costate ; lirae in last whorl 

 unequal, with granular, oblong, varicolored costse. Aperture
