stron<;ly pubescent than the female. Protessoi- Ilendersou 

 contents himself with the compromise of accepting Stimpson's 

 species as a variety of Kroyer's. In the feebleness of the 

 pubescence Mr. Brace's specimens make no very marked 

 claim upon the original specific name, to which otherwise 

 they may well iiave a right.

It has been pointed out by Professor Smith that two 

 distinct species have sometimes been confounded under tlie 

 name septemcarinata. The specimens to which that name 

 properly belongs have the rostrum obtusely rounded at the 

 tip and the telson subtruncate, its apex fringed with eight or 

 more spines. On the other hand there are specimens of 

 similar general appearance belonging to the species Sabinea 

 Sarsii, Smith, 1879, which can readily be distinguished by 

 the circumstance that the rostrum ends in an acute tip and 

 that tiie telson likewi.se has its apex acute, with one or two 

 f^pines on either side. Sars has pointed out that the M^to 

 Gaimardii of Kroyer is in fact the first larval stage of 

 Sahinea septemcarinata^ and that in a very young post-larval 

 condition that species is already sharply distinguished from 

 Sahinea Sarsii by the character of the telson. 



Mr. Bruce's specimens were obtained by the trawl off North

 the west of the Barents Sea, 76° 44'-76° 47' N., 30° 30'- 

 29°55'E., at 110 fathoms; at 76° 17' N., 21° 36' E., in
