﻿,Q CRUSTACEA MALACOSTRACA. 



Antilles; A. M.-Edwards & Bouvier (Mem. Mns. Comp. Zool, XIX, p. 139) state: "L'espece t}pique parait 



etre localisee dans la mer des Antilles , elle ne remonte pas au-dessiis de 80 brasses et descend 



jusqu'a 573", and the>' continue: "Elle est representee dans les eaux orientales de I'Atlantiqne par la 

 \ariete concolor A. ]\Iilne-Ed\vards et E. L. Bouvier du Talisman (495 a 1600 metres), et dans le Paci- 

 fique oriental par la \ariete occidcntalis Faxon de TAlbatross (495 brasses)". I think that "var. coiicolor" 

 really belongs to U.nitidiis as a variety; "var. concolor'^ has been taken by the "Caudan", "Travailleur" 

 and "Talisman" in the Gulf of Gascogne and from there southwards to the Cape Verde Islands, in 

 495 — 1710 meters, also in the Indian Ocean off Cape Natal, 440 fm. (Stebbing). Alcock (1899) gives 

 U. nifidus — presumably not the typical form but var. concolor — from the Laccadives, 636 fm., and 

 from the Bay of Bengal, 320—296 fm. It appears to me somewhat more doubtful whether var. occi- 

 den talis Faxon is a variety of i'. tiitidus or an independent species, as Fa.xon (Mem. Mus. Comp. 

 Zool. XVIII, p. loi) gives several differences between the two, but naturally I can contribute nothing 

 to the solution of the question. Fa.-con has onl\- had four specimens of his U. nitidits var. occidentalis 

 from a station in the Gulf of Panama, 458 fm. (the 495 cited above from the French authors must 

 have been an error in printing). 



Remarks. I ha\e compared the "Ingolf specimen with two specimens of U. nitidus var. 

 concolor taken by the "Talisman" and found complete agreement.

 Occurrence. This species was not brought home b\- the "Ingolf; on the other hand it was 

 taken by the "Thor" in 1903 at the following locality. 



South of Iceland: 63° 12,5' N. L., 20°o6'W. L., 300 fm.; 13 spec. 



Distribution. The species has been taken several times in the eastern Atlantic, namely, off 

 northern Africa and southern Europe between 26° 20' X. L. and 46° 40' N. L. as also at the Azores 

 (A. Milne-Edwards & Bouvier. Bonnier, Caullery). The depth was from 160 to 744 fm. Its occurrence 

 south of Iceland is interesting. 



Remark.s. Some of the specimens taken are remarkable for their quite unusual size; they are 

 much larger than those whose measurements are gi\en in the literature and I ma\- therefore give 

 some details concerning them. The largest male has the following dimensions: length from tip of 

 rostrum to end of abdomen 33 mm., thorax with rostrum 18 mm., left first leg 63 mm.; iu the 

 largest female with eggs the length of the body when stretched was 40 mm., of thorax with rostrum 

 177 mm., left first leg 56 mm.
