CRUSTACEA MALACOSTRACA. III. 



conspicuously broader than long. The antennal squama (fig. 4 a) oblong-triangular, large or moderately 

 large, conspicuously or even considerably more than half as long as the diameter of third joint. - 

 The maxillipeds have the second joint uncommonly narrow (figured by Bonnier) towards the base, 

 while the outer corner of the epipod is very broadly rounded, and the terminal corner acute, as shown 

 by Bonnier. 



The abdominal operculum in the female (fig. 4 e) somewhat reminds one of that in E. inermis ; 

 its greatest breadth is somewhat before its middle, the most lateral part broadly rounded and setiferous, 

 and from these setae the lateral margins converge strongly backwards to the median line, but the 

 distal part of each margin is distinctly concave, with the result that the terminal part of the operculum 

 is somewhat produced, and the end is narrowly rounded; the lower surface of the operculum is vaulted 

 and has a median, obtuse keel, which is low at the base and gradually higher backwards to near the 

 end of the plate. - In the male operculum the median lamella (fig. 4 c) is rather similar to that in 

 E. cornuta, but the terminal, produced, transverse part of each pleopod is shorter, without any real 

 outer tooth. But the lateral plates are very characteristic (fig. 4d); each plate is considerably narrower 

 than in E. cornuta, with the distal part of the inner margin deeply concave, with the result that the 

 produced distal part of [the plate is very narrow, much narrower than in any other species; second 

 joint of the copulatory organ is not much shorter than the plate, and the part from its base to the 

 vesicle is uncommonly long, only a little shorter than the portion containing vesicle and duct, and 

 the distal part is unusually thick and terminates in a tiny spine. - The uropods, which have been 

 well figured by Bonnier, are peculiar, as the peduncle is transverse, being widened obliquely towards 

 the median line of the animal; the endopod projects from the middle of the posterior margin, and the 

 exopod, which is much shorter and thinner, at the outer end of that margin. 



Length of the largest specimen, a female without marsupium (from Stat. 24), is 6 mm.; the 

 male (from Stat 36) is only 3 mm., but Bonnier had a male 5 mm. long. 



Remarks. Especially Bonnier's figures of the uropods and of the lateral plates of the male 

 operculum make the determination of my specimens sure. 



Occurrence. Taken by the "Ingolf" at two deep stations in the warm area. 

 Davis Strait: Stat. 24: Lat 63o6' N., Long. 56oo' W., 1199 fath., temp. 2-4; 4 spec, (and 4 frag- 

 ments). 



Stat 36: Lat. 6i5o' N., Long. 562i' W., 1435 fath., temp. 1-5; 2 spec. 



Distribution. Hitherto known only from the Bay of Biscay: Lat 44i7' N., Long. 438' W., 

 504 fath. (Bonnier). 



95. Eurycope brevirostris u. sp. 

 (PI. XIII, figs. 5 a- 5 i). 



Descrip tion. Somewhat more than twice as long as broad, and in general aspect (fig. 5 a) some- 

 what similar to E. cornuta, but very much smaller, and the middle portion of the body, especially fifth 

 thoracic segment, is broader as compared with head or abdomen than in E. cornuta, inermis, Hanscm, 

 or complanata. -- The epimera considerably produced, with a minute spine on the subacute end.
