other species of this genus described by Middendorff from specimens in 
the St. Petersburg Museum ; Verkriizen, JB. mal. Ges. ix. pp. 203-221, 
& 359. 
W. Kobelt adds some observations concerning the same specimens. He 
thinks that no Pacific form can be united specifically with B. undatum 
(L.), unites B. schrenlci with ochotense (Midd.), and grebnitzkii with 
totteni (Stimps.), but adds B. verkruezeni, sp. n., Dui Island, Saghalieu. 
B. pulcherrimum is, according to him, of a very peculiar character, and 
.perhaps no Buccinum ; 1. c. pp. 229-235. B. grebnitzkii is distinct from 
totteni ; Verkriizen, l. c. pp. 361-364.
