150 CRUSTACEA MALACOSTRACA. III. 



7 e) is extremely vaulted and the central part of its median line strongly keeled ; seen from the side 

 (fig. 7 d) the operculum is raised so much that it is shaped like a broad triangle, with the angle on the 

 lower margin rounded and situated a little behind the middle; seen from below (fig. 7 e) the operculum 

 is considerably broader than long, with the broadest part rather near the base, the anterior margin 

 with each lateral third considerably concave, the lateral angles broadly rounded, and the margins 

 behind these angles a little convex and strongly converging to the posterior margin, which is trans- 

 verse, with the median part somewhat convex. -- As to the male operculum the reader is referred to 

 Bonnier. - - Uropods with the peduncle rather small and short, considerably or much shorter than the 

 endopod, while the slender exopod is scarcely one-third as long as the endopod (fig. 4 d in Bonnier). 



Length of an ovigerous female 27 mm.; the male according to Bonnier 3 mm. 



Remarks. E. parva differs strongly in general shape and in several characters from the other 

 forms in this section, in which fifth and sixth thoracic segments are dorsally fused; the female oper- 

 culum is very peculiar. 



Occurrence. Taken by the "Ingolf" at a deep station in the warm area. 



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



Besides, it has been taken by the "Thor" at the following place. 



South-West of the Faeroes: Lat 6ii5' N., Long. g35' W., 463515 fath.; i spec. ($ ovig.). 



Distribution. Known from the Bay of Biscay: Lat. 44i7' N., Long. 438' W., 504 fath. (Bonnier).

This species has been well represented by Sars as to most particulars, so that a few notes are 

 sufficient -- Sars' figure of the front area of the head, his "frontal projection", agrees badly with that 

 found in co-types presented by him, while this area in his co-types is similar to those in my "Ingolf 

 specimens. The area (fig. 8 a) tapers anteriorly less than figured by Sars; its lateral margins are raised 

 like keels, each of which projects as a minute, triangular tooth at the end, while the anterior margin 

 of the area between these teeth is transverse, straight, moderately short and generally showing two 

 or three tiny teeth. - The antennal squama (fig. 8 a) is small, much less than half as long as the 

 diameter of third joint, slender, and tapering feebly to the truncate end, which has a single seta. 



Occurrence. Taken by the "Ingolf at two stations. 



Davis Strita: Stat. 32: Lat 6635 ; N., Long. 5638' W., 318 fath., temp. 3-9; i spec. 

 Stat. 25: Lat 633o' N., Long. 5425' W., 582 fath., temp. 3-3; 6 spec. 



Distribution. Common at the south and west coasts of Norway, going northwards to Hasvig 

 in Finmark, occurring in depths from 50 to 300 fath. (G. O. Sars, 1898), in Christiania Fjord taken in 

 4060 and even in 30 fath. (Sars 1864). A specimen was taken in Skager Rak, 15 sea-miles from the 

 lighthouse of the Skaw, 125 fath. (H. J. Hansen). Finally gathered on the "Porcupine Bank", west of 

 Ireland, 293 fath. (Tattersall), and recorded with a query from two places respectively east and west 

 at Southern Scotland (T. Scott).
