j CRUSTACEA MALACOST RACA. III. 



from the end (fig. 2 1), or nearly beyond the end (fig. 2 k) of the adjacent process; operculum slightly- 

 broader than long. — In the male the abdomen is a little longer than broad (figs. 2 a and 2h); the 

 postero-lateral processes are much larger than in the female, more than half as long as the margin 

 between them, which is incurved just above each uropod (fig. 2g); the uropods are conspicuous from 

 below, reaching a little beyond the posterior margin (u at figs. 2 g and 2 h). — The median lamella of 

 the operculum is suddenly considerably widened a little from the base (figs. 2 h and 2 i), as each lateral 

 margin is excavated near that base; the distal part of the lamella has two pairs of minute angles on 

 the outer margin, respectively a little before and a little behind the middle; the thread of the copulatory 

 organ is almost three times as long as second pleopod (fig. 2 h, c). 



Length of a female with marsupium 2 - 5 mm., of a male 2-6 mm. 



Remarks. Sars published a detailed description with figures of the female, but he overlooked 

 the dorsal fusion of the segments mentioned, and he had no male. 



Occurrence. Taken by the "Iugolf" at fifteen stations, all in cold area.

Besides, it has .been taken East of Iceland at Lat. 65°53' N., Long. 7°i8' W., 1163 fath., temp, 

 -f- ri° (G. O. Sars). 



Distribution. Taken by Sars in the cold area west of Norway at Lat. 63°5' N., 525 fath., 

 temp. -4- i-i°, and at Lat. 6g°46' N., 649 fath., temp. -4- 07 . But when Sars records it from the warm 

 area between Finmark and Beereu Eiland at Lat. 72°27' N, Long. 20°5i' E, 191 fath., temp. 3-5°, the 

 statement seems to me a little dubious, because this species otherwise has been taken exclusively, and 

 even at 18 stations, in the cold area in from 371 to 1309 fath.; perhaps the specimens from the warm 

 area belong to the following species or to another closely allied form.
