LAMPROPS FUSCATA G. O. Sars. 



Lamprops fuscata G. 0. Sars, Forh. Vidensk. Selsk. Christiania, 1864 (1865), p. 

 192.— Cnist. Norway, vol. 3, 1900, p. 20, pi. 11. 



A small and immature specimen is referred, without much doubt, 

 to tliis species, which is known from Greenland, Franz-Joseph Land, 

 Nova Zembla, and the north of Norway. 



Locality. — Albatross stsition 24:QQ ; off Newfoundland; 67 fathoms; 

 U.S.N.M. 44129. 



With this species I also associate provisionally four ovigerous 

 female specimens from Alaska. They differ from Sars' account of 

 the species in the following characters : (1 ) The size is much greater — 

 about 8.7 mm. total length; (2) the pseudorostrum is shorter, the 

 lateral plates only meeting for a very short distance in front of the 

 ocular lobe; (3) the dorsal crest on the anterior part of the carapace 

 is very strongly marked; (4) the first legs are shorter, not extending 

 beyond the pseudorostrum, but the relative lengths of the segments 

 are much as in Sars' figures; (5) the last two segments of the second 

 legs are shorter, together equaling the length of the carpus; (6) the 

 peduncle of the uropods is a little longer than the telson. As I have 

 not been able to compare the specimens with an adequate series of 

 the Atlantic and Arctic form, it would be hazardous to regard these 

 differences as specific. 



Localities. — Shahafka Cove, Kodiak Island, Alaska; W. H. Dall, 

 July 10, 1880; U.S.N.M. 44130.

It is doubtful whether this species is entitled to rank as distinct 

 from the L.fasciata of European coasts. The first of the four oblique 

 ridges on the carapace varies in distinctness and is by no means alto- 

 gether absent in European specimens, in some of which it is nearly 

 as well marked as in those from America. All the European speci- 

 mens I have seen, however, agree with Sars' figures in having only 

 one pair of lateral spines on the telson, wliile in American specimens, 

 as in Smith's description, there are at least two pairs. There are 

 also some small differences, which may be constant, in the spinula- 

 tion and proportions of the uropods.
