Distribution. On the European side of the Atlantic, this species has been taken in the 

 Bay of Gascony, 425 fm. (Cauller}), off Portugal, 1378 fm. (A. Milne-Edwards), south-west of the Azores, 

 1675 fm., and at the Canary Isles, 1675 fm. (Sp. Bate), also south of the Cape Verde Isles at 2128 fm. 

 and in the vertical net from o to 213 fm. (Ortraann). In the Mediterranean it has been taken at Mes- 

 sina (Riggio) and near Monaco, at the last place in a large net sunk to a little over 1000 fm. (Lo 

 Bianco). It has also been taken northwest of the Bermudas, 2675 fm. (Sp. Bate) and at a number of 

 places off the east coast of America between 31^41' N.l,. and 42°2'N. L., the depths varying from 105 

 to 2949 fm. (S. I. Smith). But Smith writes further (Rep. Connn. Fish.. . for 1885, p. 63), that a single 

 specimen was taken "at the surface in a dip-net, and was kept alive for half an hour". This and 

 another reason given induced Smith to write: "These facts lead me to suppose that this species is 

 not a habitual inhabitant of the bottom at great depths, but more probably a truly free-swimming 

 inhabitant of some part of the vast region intermediate between the surface and the bottom, such a 

 one as might occasionally stray to the surface or to considerable depths". The observations mentioned 

 by Ortmann and Lo Bianco of specimens taken in the vertical net agree with this. To judge from 

 the structure of the animal and from the 4 catches made by the "Thor" in 1904, Smith's supposition 

 seems quite justified. 



Whether the specimens referred by Faxon (Mem. Mus. Comp. Zool. XVIII, p. 161) with a query 

 to A. Agassizii really belong to this species, I am unable to determine; they came from the Pacific 

 in the Gulf of Panama and somewhat further south. 



Remarks. It is perhaps right to add that the specimens investigated by me certainly belong 

 to the ^i. Agassi:://' so well described and figured b)- Smith; in referring it as synonym to A. picrpiirca 

 I have only followed the authors. — At the time of capture of the specimens taken by the "Ingolf 

 at St. II and St. 12 it was noted: "animals clear, blood-red all over, eyes black".

Occurrence. The "Ingolf has not taken this .species but it was brought home in 1904 by 

 the "Thor" from the following locality. 



South of Iceland: 62°47'N.L., I5°03'W. L., 1950 m., young-fish trawl, 1500 m. wire out; i spec. 



Distribution. The species was founded on a specimen taken off the east coast of America
