In the marsupium of two females from the "Ingolf" Stat 4 I found two new genera of Crypt- 

 oniscidae (see later on). 



Occurrence. Taken by the "Ingolf at three stations. 



Between Iceland and the Faeroes: Stat. 4: Lat 64O7' N., Long. ni2' W., 237 fath., temp. 2-5; 12 spec. 



Stat 2 : Lat 63O4' N., Long. 922' W., 262 fath., temp. 5-3 ; 2 spec. 



West of the Faeroes: Stat 44: Lat 6i42' N., Long. 936' W., 545 fath., temp. 4-8; 2 spec. 



Furthermore it has been gathered four times in Baffin Bay off West Greenland between Lat. 

 724i' N., Long. 595o' W. and Lat (x)i6' N., Long. 588' W., in depths from 183 to 227 fath. (H. J. Han- 

 sen). Also gathered somewhat south-west and south-east of the Faeroes in Lat 6o3i' N., Long. 9i8' 

 W., 229 fath., and Lat 6o2i'N., Long. 54i' W., 580 fath. (Norman); by Cand. mag. Ad. Jensen (in the 

 "Michael Sars") at Lat 6oio' N., Long. 625' W., 620 fath., temp, -f- 0-15, many spec., and at Lat 6oio' 

 N., Long. 635' W., 650 fath., temp, -4- 0-53, i spec. Finally east of Iceland : Lat 6436' N., Long. io22' 

 W., 299 fath., temp, -j- 0-3 (G. O. Sars, 1885). 



Distribution. Taken at four places off Norway far from the coast, between Lat 6244' N., 

 and Lat 7i25' N., in depths from 350 to 620 fath., temp, from -4- 07 to -f- ro (G. O. Sars). Finally 

 taken off New England, Nova Scotia and New Foundland, in 250 fath. and, which must have been 

 by curious chance, in 7 fath. (Harger). 



Discarding the statement as to 7 fath. it is seen that A. granulata has been taken in depths from 

 183 to 650 fath., and both in the cold and the warm areas. But looking at the map of the Norw. 

 North.-Atl. Exp. it is seen that all five stations recorded for that expedition (18, 48, 124, 164, 200) were 

 in the cold area, but not far from the limit between this and places with a temperature above zero, 

 and the stations from the "Ingolf and those south-west or south-east of the Faeroes are not very far 

 from the same limit 



Sub-Order Oniscoidea. 



With the exception of a single genus the animals from Northern Europe and Greenland 

 belonging to this sub-order are all exclusively terrestrial, and therefore omitted here. It may only be 

 said that two species, Porccllio scaber Latr. and Oniscus murarius Cuv., have been taken by the "Ingolf 

 at Trangisvaag, Sudero (one of the Faeroes), but according to Budde-Lund (1885) both these forms,
