CRUSTACEA MALACOSTRACA. 67 



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

 temp. -^ 0-51°. 



Distribiition. 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: 76°36'N. L., 12° 10' 

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

 N. Iv., 3°5'W. L., 1462 fm., temp. -f- 1-4°. Birnla mentions a single specimen from 79^41' N.L., 4°58'E. L., 

 1560 fm., temp, -f- i'i°. The species has thus been taken at depths from 495 fm. to about 1560 fm. 

 with bottom-temperatures between -=- 0-6'' and -^- 1-4° in the waters between the Faeroes, 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 87— 87'5 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 j^revious 

 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: 70° 05' N. L., 8° 26' W. L., 371 fm., temp. -=- o'4° ; great quantity of spec.
