several in the subadult specimen figured 8 spines of different length on the inner margin, second joint 

 on the inner margin and the end with about 7 spines increasing in length from the first to the last, and the outer 

 terminal spine is almost as long as the joint. 



length of an ovigerous female 7.3 mm. 



Remarks. This fine species is easily recognizable in having the carapace somewhat low in propor- 

 tion to its length, pseudorostrum rather long and longer than in the majority of forms, a conspicuous tooth 

 near the lower margin of the frontal lobe, the two distal joints of the antennular j>eduncles long and the outer 

 flagellum uncommonly short in proportion to the last joint of the peduncle, finally by the uropods with the 

 long endopod and the relative length of its joints. 



Occurrence. Taken by the "Ingolf" at two deep-sea stations in the warm area.

Xorth-West Iceland: Dyre Fjord. 20 fath.. mud: 13 specimens. 



But this species has been secured at a good number of other localities within our area. Off West Green- 

 land it has been captured at Proven (Lat. 72*23' N.). 200 300 fath., and at Nivak (Lat. 68^36' N.), 120 fath. 

 (H. J. Hansen). The "Thor" gathered it south-west of I it-land Lat. 6346' N., Ix>ng. 225&' W., 80 fath. 

 (many hundreds of specimens), and south of Iceland: Lat. 63i8' N.. Long. 2i3o' W.. 94 fath. Furthermore 

 it has been taken at North- West Iceland by Mag. W. Lundbeck in Onundar Fjord. II 12 fath., ooze with a 

 few stones and some alga? (large number of specimens), and by Mag. R. Honing in Dyre Fjord. 10 12 fath. ; 

 off North Iceland by the "Thor" near Husa Vik. 4253 fath.; at East Iceland by Mag. R. Hairing in Fask- 

 ruds Fjord, 50 20 fath.. and by Dr. A. C. Johansen in Loons Vik. 40 fath., ooze and clay: finally south of 

 Iceland by Dr. A. C. Johansen at Vestman-Islands. 68 70 fath.. day and ooze. 



At East Greenland L Nasica has been taken two times, viz. in Hekla Havn. Lat. 70-27' N. (H. J. 

 Hansen). and in Scoresby Sound. Lat. 7O43' N.. 37 fath. (Ohlin). 



Distribution. This species has a very wide distribution. It inhabits the Kattegat, especially 

 its eastern parts, and goes southwards into the northern half of the Sound and the northern part of Store 

 Belt and Odense Fjord ; in these southern localities it has been taken in 9 fath., and even in "79" fath. ; in
