"8 CRUSTACEA MALACOSTRACA. IV. 



land: Nusak (Lat. 70 25' X., to fath.), Egedesminde, Holstensborg, Ikertok Fjord, 30 fath., Godthaab, 

 2 — 5, 3, 5 and 10 — 15 fath., and places near Prederikshaab, 5 to 15 fath. 



At Iceland it has been taken on the north-west side in Isefjord, 4 fath., by "Diana"; on the east 

 side in Bakke Fjord, 52 — 43 and 12 — 15 fath., by Dr. A. C. Johansen, and in Faskruds Fjord, 20 — 50 fath., 

 by Mag. R. Herring, finally on the south-west side at Reykjavik, 6 fath., "Diana". — At the Fseroes it has 

 been gathered in Klaksvig, 10 — 15 fath., by Dr. Th. Mortensen. 



At Fast Greenland this form has been taken at nine places recorded by Buchholz, Ohlin and K. Ste- 

 phensen, and the last-named author has put them together in his Conspectus (1913). The places are situated 

 between Fat. 76°45' N. and 73°6' N., the depths generally from i 1 ,., to ab. 10 fath., excepting a single state- 

 ment by Buchholz: 150 fath., which most probably is erroneous. Finally Mag. Kruuse secured a specimen 

 at a more southern locality in East Greenland, viz. Tasiusak, Fat. 65 '37' N. 



Distribution. The Copenhagen Museum possesses specimens from two places in Kattegat and 

 from Hornba'k, in the northern end of the Sound. Not rare along the coast of Norway, from Christiania 

 Fjord to Vadso, generally in 10 to 30 fath. (G. O. Sars). Recorded from West Spitzbergen at Fat. 79°43' N., 

 13 — 15 fath. (Ohlin) ; from various places at the British Isles, f. inst. at Northumberland and Durham, and 

 at the south coast of Devon and Cornwall (Norman) ; from places at the east coast of Baffin Fand north- 

 wards to Fat. 71 57' N., 5 — 20 fath. (Ohlin); finally from Unalaska, 8 — 12 fath. (Thiele). 



So far it is possible to walk with tolerable certainty. But according to the literature A', bipes shall 

 have a much wider distribution. Specimens of Nebalia with the eyes well developed have been found at 

 various places in the Mediterranean, at the French coast and at Madeira (N. Geoff yoyi H. Milne-Edw.) ; at 

 Cuba; in the Red Sea; at Ceylon; at Japan (N . japanensis Claus) ; at the Pribyloff Islands; at Chile (N. 

 chilensis Claus); in the Strait of Magellan; finally at New Zealand (N . longicornis Thorns.). In 1904 Thiele 

 (op. cit.) referred all these "forms" to a northern species, N. bipcs O. Fabr., and a southern species, N. longi- 

 cornis G. M. Thomson, and speaks of "subspecies". One gets the impression that our present knowledge 

 is quite insufficient, that a monograph of Nebalia based on rich material from most seas must be worked 

 out by an able Zoologist, who after a critical study of the animals and the specific characters points out 

 the limitation of the species, and consequently their distribution.

Occurrence. Taken by the "Ingolf" at a single station. 



Davis Strait: Stat. 32: Fat. 66°35' N., Fong. 56°38' W., 318 fath., temp. 3.9; many specimens. 

 Distribution. At the west coast of Norway taken off Stavanger, in Throndhjems Fjord and at 

 Fofoten, 150 — 200 fath. (G. O. Sars). Recorded from west of Ireland, 120 and 199 fath. (Tattersall) and 

 from the Mediterranean (G. Haller and Fo Bianco, test. Joh. Thiele).
