produced posteriori}', but tbe sterna! surface of the last somite 

 bears two ciirved teeth as in the female. The outer flagellum of 

 the antennules is eomposed of four segmenta. As in the female the 

 inner flagellum is equal in length to the first segment of the outer. 



Uropods (fig. 8) considerably longer than the last two somites 

 together, pedunele about one-third longer than the last somite with 

 about nine long spines and set?e on its inner edge. Endopod nearly 

 one-half longer than pedunele, the proximal segment four times as 

 long as the distal. There are very numerous spines of varjùng 

 length on the inner edge and a few on the outer edge. Exopod not 

 quite as long as the first segment of endopod. 



Remarks. — This species was described by Sars from a 

 fragmentary and immature male specimen. Korman added some 

 details from a female specimen, probably also immature. The 

 females and young in the present collection resemble closely Sars' 

 very characteristic figure and some of the specimens sent to me 

 bore labeis in Prof. Sars' haudwriting. There can, therefore, be 

 no question as to the identification, although Sars' description of 

 the inner ramus of the antennule as "rudiment?er og knudeformig'' 

 is at variance with the characters of the specimens examined by me. 



Occurrence. — Stations 17, 18, 26, 30, 39, 44, 57. Depth 

 950—1200 metres. 



Distribution. — Otf coast of Portugal, 550 fathoms (Sars); 

 at entrance of Davis Straits, 1750 fathoms (Norman).

 This species, which was described from a single immature 

 female obtained off the West of Ireland, is represented by a number 

 of specimens including adults of both sexes in the present collection. 

 Unfortunately nearly all the specimens are in poor condition and I 

 am therefore unable to add much of importance to the description 

 already given. The Mediterranean specimens are much smaller 

 than that from Ireland. A female with brood-pouch well developed 

 measures only 2.7 mm., while tbe type-specimen , thoiigh immature, 

 is 3.85 mm. in length. The structural differences however are so 

 sligbt tbat there can hardly be any hesitation in referring them to 

 the same species, The Naples specimens have generally two teeth 

 in place of one on the dorsal edge of the carapace dose to the base
