x * 2 CRUSTACEA MALACOSTRACA. III. 



margin is slightly concave somewhat before the end, which is feebly produced as a short and moder- 

 ately broad lobe; the copulatory organ has its second joint long, a good deal longer than the plate, 

 especially because the part containing vesicle and duct is two and a half times as long as the distance 

 from base to vesicle; the thick hook is placed somewhat before the end of the plate, and the distal 

 part of the inner margin of the plate inside the articulation of the hook is a little concave. — The 

 uropods have the basal joint thick and the rami are, as stated by Sars, subequal in length, but the 

 outer ramus is more slender than the inner. 



Remarks. The differences between E. cornuta and the two next species are mentioned with 

 these forms. 



Occurrence. Taken by the "Ingolf" at a single station. 



North of Iceland: Stat. 128: Lat. 66°5o' N., Long. 20 c 02' W., 194 fath., temp. o-6°; 1 spec. 



Furthermore it is known from three places in Baffin Bay, viz. Lat. 7i°io' N., Long. 58°56' \Y., 

 199 fath. (H. J. Hansen); Umanak Fjord, ab. Lat. 71 N. (H. J. Hansen) and Lille Karajak Fjord, ab. 

 Lat. 70°3o' N. (Vauhoffen). — But when Grieg (1907) recorded it as having been captured by the Duke 

 of Orleans off East Greenland at Lat. 75°58 I / 2 ' N., Long. i4°o8' W., 300 m., temp. 0-4°, and, besides, in 

 Denmark Strait at Lat. 66°42' N., Long. z(y°\d W., 550 m., temp, + o-n°, I consider these statements 

 as possible but not certain, because I do not feel convinced that in the one or in both cases the 

 animals in question have not belonged to E. inermis n. sp., formerly mixed up with E. cornuta by 

 Sars (see below). 



Distribution. It occurs "along the whole coast of Norway, from the Christiania Fjord to 

 Vadso, in depths ranging from 50 to 400 fathoms" (G. O. Sars). In Skager Rak it has been taken 15 

 sea-miles from the lighthouse of the Skaw, 125 fath. (Meinert), and at a number of places between Jutland 

 and Norway, in 130 to 340 fath. (H. J. Hansen); the "Thor" has taken it in the North Sea off southern 

 Norway: Lat. 58°32' N., Long. 4°i8' E., 148 fath. As E. robasta Harger is synonymous with E. cornuta, 

 this species is known from the Gulf of St. Lawrence, 220 fath. (Harger), but when Harriet Richardson 

 (1905) said: "Atlantic coast of North America" I do not know any observation on which this too loose 

 statement has been based, and the authoress had evidently not seen any specimen in the U. S. National 

 Museum, as she only reprinted the text of Sars. 



In 1886 Sars wrote that the Norwegian North-Atlantic Exp. had taken E. cornuta at nine 

 stations in the cold area between Norway— Spitzbergen and Iceland — the Fseroes in depths from 350 

 to 1 2 15 fath., and that the animals were in part unusually large. I am sure that all these animals in 

 reality belong to E. inermis 11. sp. and E. Hanseni Ohlin, both larger than E. cornuta, similar in aspect 

 and inhabiting the cold area. Stuxberg's statement, copied by Sars and Stephensen, that E. cornuta 

 has been taken in the Kara Sea, is also certainly wrong.

 (PI. XIII, figs. 2 a— 2 1). 



Description. Similar to E. cornuta. but larger and a little more slender (fig. 2a), as a rule 

 a little more than two and a half times as long as broad.
