length of remaining portion of spire 44 millim., breadth at 
mouth 36 millim. Here the proportions are not very different 
from those of the East-Finmark form, but the aspect is alto- 
gether different on account of the greater tumidity of the 
whorls and other characters. Sars’s pl. xiv. fig. 3 @ comes 
near to my specimen in characters of sculpture and tumidity 
of whorls, but it is more elongated in the spire. It may be 
regarded, however, as an illustration of the variety.

The figure given supplies the following measurements :— 
Length of mouth 38 millim., of remaining portion of spire 
40 millim., breadth at mouth 32 millim. This form comes 
suspiciously near to U. Turtoni, from which, among other 
points, it differs in the more regular formation of the earlier 
nuclear whorls, in which respect it agrees with U. schan- 
taricus.

Some years ago I purchased a shell from the collection of 
the late Baron Prévost, which was said to come from Japan, 
which is beyond the range of my collections and studies ; but 
this particular shell was purchased on account of its evident 
relation to arctic forms. The shell was in a paper tray, on 
which was the following account of it:—‘‘Fusus Sabinit, 
Gray, coquille recueillie dans le nord du Japan par M. A. 
Adams pendant le voyage du Samarang.” It clearly had 
nothing to do with 7. Sabint. Jeffreys was just then writing 
something on Japanese shells, and [ sent Prévost’s Fusus to 
him for his opinion. He returned it with a label “Fusus 
Turtont, not T. Sabini.” It might well be so, but I could 
not doubt that so marked a form had received a name; and 
so, while writing this paper, I sent it up to Mr. Edgar A. 
Smith to ask whether he could throw any light upon it. He 
replied that the shell was not in the British Museum, but that 
it was “ Tritonium schantaricum ot Middendorff, from Schantar 
Island, in the Okhotsk Sea.” On referring to Middendorft’s
