190 BUCCINUM. 



character not assigned to B. Japonicum: the red spotting on 

 the keels is also absent in that species ; and the color of the 

 epidermis is different. At the base of the cauda in the present 

 species there is a largish excavation ; but 1 am inclined to attri- 

 bute it to a repaired injury." 



B. FISCHERIANUM, Dall. 



Shell with four whorls, of which the upper three form less 

 than one-sixth of the entire length, though acuminated. Epi- 

 dermis smooth, thin, yellowish, marked with very fine, wavy, 

 revolving lines, not ciliated. Surface of the whorls smooth, but 

 marked with rather evident lines of growth, which are raised 

 into plicate rugosities near the suture, which is appressed. 

 Whorls inflated, amply rounded, solid, porcellanous and strong. 

 Aperture elongate-ovate; outer lip thickened, broadly, eff'usely 

 arched. Peristome white. Throat of a muddy pink. Inner lip 

 with a thin callus, thicker on the columella, where it is colored 

 with a dash of deep pink. Columella twisted, broad, arched. 

 Canal wide and shallow, A T ery short. Color externally yellowish 

 pink, upper whorls a little livid, last whorl with a few indistinct 

 revolving brown lines, frequently interrupted. Traces of obscure 

 revolving ridges appear in a few places on the last whorl. 



Length 1*3 in., lat. *9 in. 



St. George's Isl., Behring's Sea. 



Described from one perfect specimen and fragments obtained 

 in 1868. Its nearest ally is that form of B. cyaneum described 

 by Fischer as Volutharpa Morchiana. From this it is very 

 doubtfully distinct. 



B. PICTUEATUM, Dall. 



Shell of moderate size, rather slender, with acute apex, sculp- 

 tured with fine wavy stride, the interspaces between which are 

 usually flat, but occasionally rise above the general surface as 

 flattened threads ; junior whorls with seven to nine faint, very 

 oblique transverse costae, the prominence of which varies in 

 different specimens ; epidermis very thin, smooth, dehiscent ; 

 color whitish, painted with oblique, reddish brown flammules, 

 irregularly distributed in patches transverse to the whorls ; 

 columella twisted with a strong fasciole, lightly glazed ; outer
