call] new species of sheles 147 



mental lines which lirate the spiral sculpture ; aperture milk-white ; 

 outer lip thickened, reflected, excavated behind ; body with a glossy 

 white callus which extends the whole length of the pillar, which is 

 short, obliquely truncate in front ; canal wide, shallow, recurved, 

 with a moderate fasciole ; operculum gray, with a laterally subcentral 

 nucleus. Lon. of shell, 49; of last whorl, 35 ; of aperture, 26; maxi- 

 mum diameter of shell, 28 mm. 



Station 5067, in Surugo Gulf, south coast of Nippon, Japan, in 

 29 fathoms. U. S. Nat. Mus., 110,526. 



Apparently nearest to B. polare, but destitute of axial ribbing and 

 with a more acute spire. 



BUCCINUM KADIAKENSE Dall, n. sp. 



Shell small, acute, yellowish white, with about six sharply sculp- 

 tured wdiorls ; suture distinct, not appressed ; axial sculpture of (on 

 the last whorl of the type about 12) oblique, rounded, wave-like 

 ribs, with wider interspaces, evanescent beyond the periphery ; also 

 of fine, prominent incremental lines ; spiral sculpture of more or less 

 alternated, distinct rounded threads, one at the periphery slightly 

 more conspicuous than the others ; the threads on the base, as usual, 

 stronger than the others ; aperture elongate, narrow, body and pillar 

 callous, white, a slight, oblique ridge on the pillar near its anterior 

 edge ; pillar long, straight, white ; canal wide, hardly recurved. Lon. 

 of shell, 21 ; of last whorl, 13.5 ; of aperture, 9; maximum diameter, 

 8.5 mm. 



Kadiak Island, between tide marks, Alaska. U. S. Nat. Mus., 

 110,527. 



This little species recalls Buccinum ciliatum Fabricius in its sculp- 

 ture, but is much more slender and has a more acute and propor- 

 tionately longer spire. The aperture is not quite completed, but the 

 nucleus of the operculum is subcentral. 



BUCCINUM ANIWANUM Dall, n. sp. 



Shell of moderate size, with about six evenly rounded, rapidly in- 

 creasing whorls ; suture distinct, not appressed ; spiral sculpture prac- 

 tically the same over the whole surface, consisting of fine, subequal, 

 flattish threads, usually paired and arranged in fasciculi of three 

 pairs ; these are crossed with extremely minute, elevated, incremental 

 lines which microscopically reticulate the sculpture, showing strong- 

 est in the narrow grooved interspaces ; aperture semilunar, outer lip 

 (defective); body with a thin wash of glossy callus; pillar thin, 

 white, its edge in front gyrate and almost pervious ; throat white,
