The differences between this species and M. longipes are pointed out in the notes on the 

 latter form. 



There is scarcely more than a single point to add to the accounts given by Sars and myself. 

 But that point is a morphological observation of interest. Fig. 5 a represents the proximal parts of 

 the left maxilliped seen from below and attached to its sternite (st). The small transverse plate, pcx, 

 is the hitherto undiscovered prascoxa of the maxillipeds, placed between the sternite (st) and the coxal 

 joint, ex, generally considered as the first joint. The piece marked has is the proximal part of the 

 "basis", generally described as the second, long joint of the maxillipeds. So much may be said here; 

 the whole morphological question has been dealt with on p. 9. — It may be noted here that the exo- 

 pod of fourth pair of pleopods is rather broad, lamellar, with the end obtuse. 



Among the large material seen by me I have found only a single female with the marsupium 

 fully developed; this female, from the Kara Sea, is 33 mm. long; the general size of the male is 24 

 — 25 mm. 



Occurrence. Taken by the "Ingolf" at seven stations, all in the cold area. 



North of the Faeroes: Stat. 140: Lat. 63°29' N, Long. 6°57' W., 780 fath., temp, -f- 0-9°; 2 spec. 



— - - Stat. 138: Lat. 63°26' N, Long. f<£ W., 471 fath., temp. -4-06 ; 4 spec. 

 East of Iceland: Stat. 103: Lat. 66°23' N., Long. 8°52' W., 579 fath., temp. -4- o-6°; 1 spec. 



— - — Stat. 101: Lat. 66°23' N., Long. i2°05' W., 537 fath., temp. -4-07°; 10 spec. 

 North of Iceland: Stat. 126: Lat. 67°i9' N., Long. I5°53'W., 293 fath., temp. H- 0-5° ; 4 spec. 



— - Stat. 124: Lat. 67°4o'N, Long. i5°4o' W., 495 fath., temp. -=- o-6°; 2 spec. 

 South of Jan Mayen: Stat. 116: Lat. 70°05' N., Long. 8°26'W., 371 fath., temp. -=- 0-4°; 1 spec. 

 It has been taken in Denmark Strait off East Greenland at Lat. 66°42' N, Long. 26°4o' W., 292 



fath., temp. +o-ii° (Grieg), and east of Iceland: Lat. 64°53' N., Long io°oo'W. (Grieg). 



Distribution. Taken by Admiral Wandel a little south-east of the Fseroes: Lat. 6i°23' N., 

 Long. 4°2i' W., 505 fath., temp, -j- 04 , 1 spec. It was recorded from the Fteroe Channel, 540 fath. (Nor- 

 man) and from a place north-east of the Fceroes: Lat. 63°o6' X., Long. 2°46' W., 483 fath., temp. -4- 1-07° 

 (Grieg). Sars recorded it from three stations in the cold area west of Norway, 350 to 634 fath., from 

 two places in the cold area west and south-west of Beeren Eiland, 447 and 658 fath., finally from two 

 places north-west of Spitzbergen, respectively 459 fath., temp. -4- ro D , and Lat. 80=3' N, 260 fath., temp. 

 + i-i°. Furthermore recorded from King Charles Island, East Spitzbergen, 32—37 fath. (Ohliu), from 

 near Beeren Eiland, 40 fath. (Hoek), from Novaya Zemlya (Richardson), and it is very common in the 

 Kara Sea, 20 — 100 fath. (several authors). 



That I consider M. giganteus forma australis Vanhoffen from the antarctic deep-sea as a dif- 

 ferent species is already mentioned.
