material at hand he refrained from naming it. With Hansen's opin- 

 ion, after examining actual specimens, I am in agreement, and I there- 

 fore name the species after its discoverer. The species may be recog- 

 nized by the characters of the telson, the ocular plate, and the antennal 

 scale.

PARAMBLYOPS ROSTRATA Holt and Tattersall 



Paramblyops rostrata Holt and Tattersall, 1905, p. 125, pi. 21; 1906b, p. 

 26.— Hansen, 1908a, p. 108 ; 1927, p. 25, pi. 1, figs. 7a-c. 



Occurrence. — East coast of United States: Albatross station 

 2180, 2 males. 



Distribution. — This is the first record of this species from the 

 American side of the Atlantic slope. First described from the west 

 coast of Ireland, this species has since been recorded from the eastern 

 Atlantic slope from the Bay of Biscay to the Faroe Islands and Ice- 

 land, and from the Mediterranean. It forms part of the boreal fauna 

 of the North Atlantic, which extends southward on both eastern and 

 western sides wherever suitable conditions of depth and temperature 

 are available. 



Remarks. — The two specimens are in a very poor state of preserva- 

 tion, but they clearly belong to this species.

 time. It is known from the eastern Atlantic slope from Norway to 

 the Bay of Biscay, Iceland, and Greenland, in depths of 65 to 500 

 fathoms.
