Occurrence. The "Ingolf' has not taken this species. 



It is given from 79 38' N. L. at Grinnell Land (Miers). According to Ortmann (1901), Ohlin 

 (1895) and myself in Malac. Groenl. the species is common through Smith Sound, on both sides of 

 Baffin Bay and along the east coast of Davis Straits; the numerous depths noted all lie between 

 2 3 fm. to 3040 fm., but it is doubtful as yet whether depths a little greater are correct, as the 

 specimens, which certainly at times live pelagically, might be taken in the apparatus on hauling in. 

 At East Greenland it is likewise common; it was repeatedly taken at Tasiusak and a little north of 

 this to 66 15' N. L. (i st Amdrup Exped.), further in enormous numbers in the eel-seine in 70 fm. at 

 7o5o'N. L., 223i'W. L., and two specimens at Sabine Islands: 74 I / 2 N. L., i8 2 / 3 W. L. (2 nd Amdrup 

 Exped.); Buchholz had already noted it from the last-named locality and from Cape Philip Brooke 

 (74 56' N. L., 17 36' W. L.); Ohlin gives it from 4 East Greenland localities, lying respectively in 

 Scoresby Sound and north of Kaiser Franz Joseph Fjord. It was also taken by the 2 nd Amdrup Ex- 

 pedition at Jan Mayen, where it had been observed previously in quite enormous quantities (G. O. 

 Sars). Further, according to material in the Copenhagen Museum, it has often been taken at Iceland, 

 both on its west coast (Reykjavik and Faxe Fjord), north coast (Onundar Fjord, Ofjord) and east 

 coast (Seydis Fjord and Rode Fjord), but has not been met with on its south coast and seems to be 

 absent at the Fseroes. 



Distribution. The species is arctic. It is known from West Finmark (Sp. Schneider), East 

 Finmark (G. O. Sars), Murman Sea, Sea of Kara and Siberian Arctic Ocean to the east as far as 

 85 E. L,. (Stuxberg); further, it is common round Spitzbergen (several observers). According to Packard 

 it is "abundant along the whole coast" of Labrador, but Stimpson's statement of its occurrence on 

 the north-east coast of the States is extremely doubtful according to Smith. Lastly, it is given from 

 the Bering Sea (Richters). It is usually found in 2 to 20 fm. and there are several notes of its 

 occurrence in 30 70 fm., but these last I think are not so reliable, as I believe it possible as already 

 mentioned that the specimens on the occasions were taken in the apparatus on hauling iu. - - The 

 variety M. rclicta found in brackish and fresh water is omitted here. 



Remarks. The largest female (from East Greenland at 70 50' N. L.) is 297 mm. long from 

 front end of rostrum to tip of telsou; a large male is 26-4 mm. long. Ohlin reports that his largest 

 specimen from Smith Sound was 33 mm. long.

Occurrence. The "Ingolf has not taken this species. 



At West Greenland it has sometimes been taken, thus in Disco Bay, at Godhavn, Jakobshavn,
