Fusus ceramidus Dall, Bull. Mus. Comp. Zool. xviii, p. 171, June, 1889. 



Shell of a waxen or brownish yellow color, of a peculiar waxen sub- 

 translucency, nine-whorled, strongly transversely ribbed, with obscure 

 spiral sculpture, and an imbricated band in front of the suture. Nucleus 

 white, smooth, small but swollen. Transverse sculpture of seven or 

 eight rounded ribs, stouter and more prominent on the early whorls, 

 and on most of them not quite reaching the suture ; also sharpish lines 

 of growth which in front of the suture are elevated into flattish, some- 

 what irregular imbricated scales, forming a narrow band in front of 

 the suture. Spiral sculpture of primary and finer secondary threads, 

 one or two of the former near the periphery becoming sharper and more 

 prominent as they pass over the ribs ; on the later whorls all the spiral 

 sculpture has a worn or partially obsolete appearance. Aperture large, 

 canal moderate, curved to the left ; outer lip not much thickened, in- 

 ternally Urate ; a callous ridge on the body, near the outer lip ; the 

 inner lip smooth, or with a few lirae near the canal. Maximum longi- 

 tude of shell, 46.5; of last whorl, 32; of aperture and canal, 26; max- 

 imum latitude of shell, 18.7 mm . 



Hab.— Near Barbados, in 73 to 103 fathoms, sand ; bottom temper- 

 ature 60° to 71° F.

Shell small, slender, white, eight- whorled; nucleus milk-white, 

 strongly transversely plicate below, above smooth, rounded; spiral 

 sculpture of (on the last whorl eighteen) strong rounded threads of which 

 four or five are visible on the upper whorls ; these are slightly swollen, but 

 not keeled, where they pass over the ribs ; between these are numerous 

 fine close-set threads slightly marked by inconspicuous lines of growth. 

 The transverse sculpture consists of (on the last whorl ten) rounded, 

 rather close, stout ribs, which pass clear over the whorl and are straight
