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 1 at three stations. 



Between Iceland and the Faeroes: Stat.4: Lat. 64°07' N., Long. n°i2'W., 237 fath., temp. 2-5°; 12 spec. 



Stat. 2: Lat. 63°04'N., Long. 9°22' W., 262 fath., temp. 5-3° ; 2 spec. 



West of the Faeroes: Stat. 44: Lat. 6i°42' N., Long. 9°36' W., 545 fath., temp. 4-8°; 2 spec. 



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

 72°4i'N., Long. 59°5o' W. and Lat. 69°i6' N., Long. 58°8'W., in depths from 183 to 227 fath. (H.J. Han- 

 sen). Also gathered somewhat south-west and south-east of the Fseroes in Lat. 6o°3i' N., Long. 9°i8' 

 W., 229 fath., and Lat. 6o°2i'N., Long. 5°4i' W., 580 fath. (Norman); by Cand. mag. Ad. Jensen (in the 

 "Michael Sars") at Lat. 6o°io' N., Long. 6°25' W., 620 fath., temp, -f- 0-15°, many spec, and at Lat. 6o°io' 

 N., Long. 6°35' W., 650 fath., temp, -f- o'53°, 1 spec. Finally east of Iceland: Lat. 64°36' N., Long. io°22' 

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



Distribution. Taken at four places off Norway far from the coast, between Lat. 62°44' N., 

 and Lat. 7i°25' N., in depths from 350 to 620 fath., temp, from -f- 07° to -=- i-o° (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 Fseroes 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, Porcellio 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,
