40 CRUSTACEA MALACOSTRACA. 



Antilles; A. M.-Edwards & Bouvier (Mem. Mus. Comp. Zool, XIX, p. 139) state: "L'espece typique parait 



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



jusqn'a 573", and they continue: "Elle est representee dans les eaux orien tales de 1'Atlantique par la 

 variete concolor A. Milne-Edwards et E. L. Bouvier du Talisman (495 a 1600 metres), et dans le Paci- 

 fique oriental par la variete occidentalis Faxon de 1' Albatross (495 brasses)". I think that "var. concolor''' 

 really belongs to U.nitidus 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. nitidus -- presumably not the typical form but var. concolor -- from the Laccadives, 636 fm., and 

 from the Bay of Bengal, 320296 fm. It appears to me somewhat more doubtful whether var. occi- 

 dentalis Faxon is a variety of U. nitidus or an independent species, as Faxon (Mem. Mus. Comp. 

 Zool. XVIII, p. 101) gives several differences between the two, but naturally I can contribute nothing 

 to the solution of the question. Faxon has only had four specimens of his U. nitidus 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 have 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 by 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,., 2Oo6'W. L., 300 fm.; 13 spec. 



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

 northern Africa and soiithern Europe between 26 20' N. 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. 



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

 much larger than those whose measurements are given in the literature and I may 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.; in 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.
