from Kisenmima, Rikuzen, is related to B. viridum Dall.^ from off 

 California in deep water, and also known from Bering Sea, but it 

 differs from that in the minute sculpture. It is also a somewhat 

 larger and less inflated shell than B. viridum.

A specimen from Akkeshi, Kushiro, is figured. It measures, length 

 69, diameter 44 mm. The spire is dull reddish brown, fading on the 

 last whorl to rusty cream color. The aperture is brownish yellow 

 within, becoming dull reddish deep in the throat, the columella and 

 inner lip largely piu-e white, but with some j'cllow stain in the middle. 

 The sculpture of coarse waves reminds one of B. undatum. On the 

 last whorl there is a spiral sculpture of unevenly spaced low spiral 

 threads and shallow grooves at intervals, the whole covered with very 

 close, fine, decurrent waxy spiral lines. On the penultimate whorl the 

 spaced grooves run in pairs, and the finer sculpture is less distinct. 

 The next earlier whorl has low spiral cords, and the preceding two have 

 a sculpture of about 6 spiral cords running over slightly arcuate longi- 

 tudinal rounded ribs, somewhat as in a Latirus. The apex is worn. 



While this example has much resemblance to Kobelt's figures of 

 B. Uschkeanum Lob., yet it seems referable to B. middendorfji.

The figures represent an example agreeing well with Kobelt's figure 

 of the type, except that the longitudinal waves are almost obsolete. It 

 is white with a creamy or brownish tint, and somewhat profusely 

 maculate wdth rusty brown. The last whorl has 5 spiral ribs, the 

 upper one weakly nodose, the others hardly perceptibly so. It is 

 strongly puckered below the suture. The surface is finely and very 

 closely engraved with minute, clear-cut spiral lines mingled with 

 coarser ones. Length 45.5, diameter 28.5 mm. 



Another example (pi. 19, fig. 3; pi. 20, fig. 3), from Akkeshi, Kushiro, 

 has the primary spiral ribs much smaller, the secondary threads larger, 

 the same minute engraved lines being present. The whorls are also 

 obliquely waved above the periphery. The lip is white, but the 

 interior of the aperture is brownish ochraceous. Length 48, diameter 

 30 mm.
