than the first. First tarsal joint very small, triangular, terminating dor- 
sally as a small lappet, and slightly convex ventrally, where it is beset 
with a few slender bristles. Second tarsal joint beset with short spiniform 
bristles; the ventral (‘inner’) side is somewhat lamellarly expanded at 
the base, and is here armed usually with 6 strong, anteriorly curving 
spines, the 2 distal ones in most cases being in juxtaposition. Claw 
powerful, slightly curved, about half as long as ¢s.2; aux. cl. very small, 
though distinctly developed. At the distal end of f are 1 or 2 strong 
bristles, and another projects from a slight depression on the dorsal side 
of #.2, a short distance from its distal end.

Distribution.—Tf all the synonyms given above properly belong to 
this species its distribution covers a great range. It has been found 
along the coasts of the British Isles, Holland, Denmark, Norway, Green- 
land, the eastern coast of North America as far south as Massachusetts, 
and the present record extends its range to the western coast of North 
America from Orca to Unalaska. It ranges in depth from the shore 
rocks to roo fathoms (Sars). Apparently it is a truly circumpolar 
species. 
Remarks.—The specimens which I have examined from the Alaska 
coast agree very closely with the excellent description of this species 
given by Sars. They are, however, most of them considerably larger, the 
smallest specimen, from Orca, measuring about 3.5 mm., those collected 
at Popof Island 4.5 mm. to 5 mm., and those from Dutch Harbor 5.5 
mm. from the tip of the proboscis to the tip of the caudal segment. Sars 
describes the color as “a more or less vivid red,” or “‘sometimes dark- 
brownish or a sepia tint.” Most of the Alaska specimens (alcoholic) are 
lighter than this, especially those from Dutch Harbor, which are a light 
brown or yellowish; the specimens from the Shumagins are a darker 
brown, and in 2 or 3 of them the branches of the intestine in the legs
