CRUSTACEA MALACOSTRACA. III. 



Rocinela Leach. 



Of this genus only a single species is known with certainty from our area, but a second species 

 of somewhat doubtful origin must also be mentioned. 



119. Rocinela danmoniensis Leach.

Schiodte & Meinert recorded the length of females with marsupium to be 24—27 mm., but an 

 ovigerous female from the "Ingolf" Stat. 44 is 30 mm. long, the same length as recorded by the authors 

 named as the greatest for females without marsupium. — According to Sars it has been taken on "the 

 skin of fishes of various kinds, for instance the common cod, the haddock, the ling, etc." 



Occurrence. Captured by the "Ingolf at two stations. 



West of Iceland: Stat. 98: Lat. 65°38' N., Long. 26°27' W., 138 fath., temp. 5-9°; 1 spec. 



South of Iceland: Stat. 54: Lat. 63°o8' N., Long. i5°4o' W., 691 fath., temp. 3-9°; 5 spec. 



According to Schiodte & Meinert, and specimens later received by the Copenhagen Museum, 

 this species has been gathered some times at or rather near the Fseroes by various collectors, thus at 

 Thorshavn and off Akraleite, ab. 150 fath. The "Thor" captured it at two places south-west of the 

 Fseroes, viz., in Lat. 6i°i5' N., Long. 9°35' W., 463—515 fath., and Lat. 6i°o8' N., Long. 9°28' W., 435 fath. 



Distribution. Taken at some places in Kattegat and the northern part of the Sound in 

 depths from 4 to 16 fath. (H. J. Hansen); north of Kattegat in Lat. 56°54' N., 26 fath. (Zirwas); at Va- 

 deroerne, west coast of Sweden, 80 fath. (Sch. & Mein.), and along the coast of Norway from the Chri- 

 stiania Fjord northwards at least to Trondhjem Fjord (G. O. Sars). Furthermore taken by the "Thor" 

 north-east of Shetland, Lat 6i°3i' N., Long. o°39' W., 104 fath., and west of the Shetland Isles, 203 and 

 250 fath. (Norman); at Polperro and Plymouth in the Channel (Bate; Norman); west part of the Chan- 

 nel, west of Britany, and the inner, most southern part of the Bay of Biscay (K. Stephensen). In the 

 three last-named localities it has been taken pelagic, with 25, 65 and 60 m. wire out. But when 

 Stephensen, on the authority of Cams, mentions that it has been taken in the Mediterranean, it seems 

 to me somewhat doubtful (on the authority of Marion, Cams recorded it from Marseille); several car- 

 cinological statements in Carus' book ought, until further evidence, to be discarded as based on a 

 mere compilation of earlier and not infrequently erroneous determinations.

This characteristic species was established on a male from Vladivostock. Bovallius described 

 the ovigerous female ; he had purchased two specimens "of the naturalist-merchant Wessel in Hamburg",
