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 difl'erent. At the base of tlie caiida in the present 

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

 bute it to a repaired injury." 



B. FiSCIIERIANUM, Dall. 



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



than one-sixth of the entire lengtli, though acuminated. Ei)i- 



dermis smooth, thin, j-ellowish, marlved Avitli very fine, wav^', 



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



marked with rather evident lines of growtli, wliich 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, effusely

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. PICTURATUM, Dall. 



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

 tured with fine wavy stri.ne, the interspaces between which are 

 usually fiat, but occasionally rise above the general surface as 

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

 oblique transverse costae, the prominence of Avhich varies in 

 difterent specimens; epidermis very thin, smooth, dehiscent; 

 color whitish, painted with oblique, reddish brown flammules, 

 irregularly distributed in jjatches transverse to the whorls ; 

 columella twisted with a strong fasciole, lightly glazed ; outer
