CRUSTACEA MALACOSTRACA. 67 



Further, two specimens were taken by the "Michael Sars" at 63 3' N. L,., 6 32' W. L., 975 fm., 

 temp. -f- 0-51. 



Distribution. The species was founded on specimens from a station between Jan Mayen 

 and Finmark, mo fm., temp. -=- 1-3; it was also taken in the stomach of Rhodichthys regina in the 

 same waters in 1280 fm. (G. O. Sars). Ohlin gives it from three localities, one being between Green- 

 land and Jan Mayen, depth 1064 fm., the second near the west coast of Spitzbergen: 7636'N. L., i2io' 

 E. L., 930 fm., temp, -r- 1-3, the third almost midway between Spitzbergen and East Greenland: 77 52' 

 N. L., 35'W. L., 1462 fm., temp, -4- 1-4. Birula mentions a single specimen from 79 41' N. L,., 458'E. L,., 

 1560 fm., temp, -r- ri. The species has thus been taken at depths from 495 fm. to about 1560 fm. 

 with bottom-temperatures between -=- o - 6 and -f- 1-4 in the waters between the Fseroes, Iceland, 

 Norway, Spitzbergen and East Greenland with negative bottom-temperature at considerable depths. 



Remarks. The largest specimens I have are females with eggs from St 104, 117 and 118, 

 and they measure 8787-5 mm. From St. 119 there is a female with eggs 81 mm. long, from St. 105 

 a similar female 73-5 mm., from St 125 and 140 two females with eggs 75 mm. long and from the 

 last station a female with eggs only 69 mm. long. Sars gives the length "up to 95 mm."; I must 

 suppose that he has measured from the tip of the rostrum (not, as suggested by Ohlin, from the 

 end of the antennal scale) to the end of the telson. - - The antennal scale varies a little in form with 

 the size of the animal: its terminal margin is less oblique and scarcely so curved in the large speci- 

 mens as in the small, and distally it is a trifle broader in the large than in the small specimens.

Occurrence. The "Ingolf" has taken this species at 8 stations. Just as for the previous 

 species, the stations lie in the Northern Ocean, within an area which to the east is bounded by a 

 line from Jan Mayen to the Fseroes and also extends so far to the west as to pass to the north round 

 the north-eastern end of Iceland and southward round East Iceland down to the Fseroes. The stations 

 are as follows: 



St 116: 7005'N. L,., 8 26' W. L., 371 fm., temp. 0-4; great quantity of spec.
