The differences between this species and M. longiprs 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. 

 Hut that point is a morphological observation of interest Fig. 53 represents the proximal parts of 

 the left maxilliped seen from below and attached to its stemite (j/). The small transverse plate, frx, 

 !> the hitherto undiscovered pnecoxa of the maxillipeds, placed between the sternite (*/) and the coxal 

 joint, ex, generally considered as the first joint The piece marked Aor 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 niarsujmiin 

 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 1 at seven stations, all in the cold area. 



North of the Faeroes: Stat 140: Lat6329' N., Long. 6$f W., 780 fath., temp. + 0-9; 2 spec. 



Stat 138: Lat 6326' N., Long. 756' W., 471 fath., temp. -5-06; 4 spec. 



But of Iceland: Stat. 103: Lat 6623' N., Long. 852' W., 579 fath., temp. *- 06; i spec. 

 Stat 101: Lat 6623'N., Long. i2os' W., 537 fath., temp. -7-07; 10 spec. 



North of Iceland: Stat 126: Lat 67i9' N., Long. 15*52' W., 293 fath., temp. ^ 0-5"; 4 spec 

 Stat 124: Lat 674o' N., Long. i54o' W., 495 fath., temp, -f- 0-6; 2 spec. 



South of Jan Mayen: Stat 116: Lat To'os'N., Long. 826' W., 371 fath., temp. -4- 0-4; i spec 



It has been taken in Denmark Strait off East Greenland at Lat 664a' N., Long. 2o4o' W., 292 

 fath., temp. +0-11 (Grieg), and east of Iceland: Lat 64S3' N i L n io"oo'W. (Grieg). 



Distribution. Taken by Admiral Wandel a little south-east of the Faeroes: Lat 6i23'N., 

 Ixmg. 42i' W., 505 fath., temp. -i- 0-4, i spec It was recorded from the Faroe Channel, 540 fath. (Nor- 

 man) and from a place north-east of the Faeroes: Lat 63o6' N., Long. 2*46' W., 483 fath^ temp, -h 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 Spitsbergen, respectively 459 fath., temp, -*- it>, and Lat 8o3' N., 260 fath., temp. 

 -f 1-1. Furthermore recorded from King Charles Island, East Spitzbergen, 3237 fath. (Ohliu), from 

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

 Kara Sea, 20100 fath. (several authors). 



That I consider M. gigantcus forma aus/ra/ts Yanhoffen from the antarctic deep-sea ax a dif- 

 ferent species is already mentioned.
