Tliis species has never been taken in Baffin Bay, Davis Straits or waters south of Cape Fare- 

 well, nor to the north-west or north of Iceland except at the St 126 mentioned: north of East Ice- 

 land. To the west, south-west and south of Iceland it was taken a number of times by the "Thor", 

 which also found it in Rode Fjord on the east coast of Iceland; it has been taken by several in- 

 vestigators over the ridge between the Faeroes and Iceland, and it is also common round the Fceroes. 

 It was taken by Ryder's expedition near Jan Mayen, from which it is also noted by Koclbel. Ohliu 

 mentions it from two places at East Greenland, namely, 72° 42' N. L., 14° 49' W. L. and from a place a 

 little further north off Kaiser Franz Joseph Fjord; Buchholz mentions it from Cape Wynn in 74°3o'N.L,., 

 19° W. L. 



Distribution. From the Faeroes this species extends southwards along the British Lsles 

 (several observers), it also occurs in the Atlantic off France (Norman, Hansen, Holt & Tattersall), off 

 Portugal (Norman), near the Gorringe Bank oft Gibraltar (Hansen) and in the western part of the 

 Mediterranean at least to Messina (Lo Bianco, Hansen). It was next taken in the Kattegat (Intern. 

 Explor.), Skager Rak (Metzger, Meinert), at Bohuslan (Goes), along the whole coast of Norway from 

 Christiauia Fjord to Vadso in East P^inmark (G. O. vSars), in the White Sea (Jarzynsky), in the Barents 

 Sea (Breitfnss), at 75° N. L., 12° E. L. (Goes), lastly in the North Polar Sea by the '-Fram" at ca. 81° N. L., 

 124° E. L. On the east coast of North America it has been found in the Gulf of St. Lawrence, at 

 Nova Scotia, in Massachusetts Bay and as far to the south as ca. 40° N. L. Richters gives it with a 

 query from the Bering Sea, but this determination is certainly extremely doubtful. Holt & Tattersall 

 in 1905 and 1906 contribute to our knowledge of the distribution of the species in bathymetric regard; 

 extremely important information on the same theme is given by S. I. Smith (1879) ^"'^^ ^^- ^- I'owler 

 (1905). I am not able to add to our knowledge in this regard, but may note, however, that the species 

 was twice taken (only i spec, each time) in the so-called cylinder-net, an apparatus often towed near 

 the surface by the "Ingolf when steaming at its usual rate. 



Remarks. I have arrived at the result that Holt .S: Tattersall's ^kiww^ Mcganyctiphancs ought 

 to be accepted. The two authors pointed out an excellent generic difference in the female sex between 

 this new genus and Nyctiphancs G. O. Sars; I can add that in the male the clasping organs of the 

 first pair of pleopoda differ exceedingly from each other in the two genera.
