NO. 2295. NEW NORTH PACIFIC MOLLUSKS—DALL. 329 



spiral sculpture in minor particulars like that of B. angulosum, but 

 with four strong rounded cords, with much wider subequal inter- 

 spaces on the last wiiorl and eight or more irregular feeble ribs 

 obsolete in front of the suture also on the base ; other axial sculpture 

 of very fine hardly visible incremental lines; aperture creamy white, 

 the outer lip thin, hardly reflected, the body glazed, the pillar slender, 

 arcuate, short, with a deep short, rather v/ide canal and a strong 

 siphonal fasciole; the periostracum thin, pale yellowish, smooth. 

 Height of shell, 46; of last whorl, 36; diameter, 28 mm. U. S. 

 Nat. Mus. Cat. No. 221455. 



Type-locality — Point Belcher, Arctic coast of Alaska, on the beach:

CANTHAKUS EXANTHEMATUS. new species. 



Shell small, brownish, with a smooth turbinate rapidly enlarging 

 nucleus of three and a half whorls and three and a half subsequent 

 whorls; suture obscure, somewhat undulate; axial sculpture of (on 

 the penultimate whorl about 18) obscure vertical ribs with somewhat 

 narrower interspaces, extending on the last whorl to the base, and 

 cut by the spiral sculpture into conspicuous nodules; there are also 

 fine slightly raised close-set, incremental lines most conspicuous in the 

 interspaces; the spiral sculpture consists chiefly of a pair of peripheral 

 threads conspicuously nodulating the ribs and another similar thread 

 in front of the suture; as the shell grows, intercalary not nodulous 

 small threads appear in the mterspaces, and on the last whorl a few 

 still smaller intercalaries begin; this sculpture also is found on the 

 base; aperture semilmiate, simple, body erased; pillar short, canal 

 short, slightly recurved; the interior of the outer lip has five short 

 prominent lirations, similar and subequally spaced; height of shell, 

 8.5; of last whorl, 6; diameter, 4.2 mm. U. S. Nat. Mus. Cat. No.

Type-locality — U. S. Fish Commission station 2837, off Lower

ANACHIS PHANEA, new species. 



Shell small, acute, slender, white, with six flattish whorls exclusive 

 of the smooth glassy nucleus of about one whorl; suture distinct; the 

 first two whorls flat and smooth, the subsequent whorls with (on the 

 last whorl about 14) nearly vertical narrow, straight, rather sharp 

 ribs with shallow much wider insterspaces extending over the 

 periphery; surface polished, base attenuated, smooth, aperture 

 narrow, outer lip simple, body erased, pillar short, axis pervious; 

 canal short, deep, Avide, with a marked siphonal fasciole bordered 

 behind with a brown line ; there are a few feeble spiral striae on the
