length of remaining portion of spire 44 millim., breadth at 

 mouth 36 railhm. 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 

 wliorls and other characters. Sars's pi. xiv. fig. 3 a 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 tlie 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 Prevost, 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 Sabinii, 

 Gray, coquille recueillie dans le nord du Japan par M. A. 

 Adams pendant le voyage du Samarang." It clearly had 

 nothing to do with T. Sahini. Jeffreys was just then v/riting 

 something on Japanese shells, and I sent Prdvost's Fusus to 

 him for his opinion. He returned it with a label ^'Fusus 

 2'urtotii, not T. Sahini^ 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 Uj) 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 6c/«a«<ancM»« of Middendorff, from Schantar 

 Island, in the Okhotsk Sea." On referring to MiddendorfF's
