edge shorter than the hind margin, the thumb-like process rather short. The 

 2 anterior pairs of pereiopoda with the dactylus unusually elongated, fully as 

 long as the propodal joint; antepenultimate pair with the basal joint oblong 

 quadrangular, much greater in length than in breadth ; penultimate pair very slen- 

 der, considerably exceeding half the length of the body; last pair with the basal 

 joint obliquely expanded, posterior edge strongly arched and distinctly serra- 

 ted, terminal part of the leg rather slender. Last pair of uropoda in female 

 with the inner ramus scarcely half the length of the outer, conical in form, 

 and tipped by 2 small setse ; those in male with both rami lanceolate and 

 nearly equal-sized. Lobes of telson obliquely truncated at the tip, forming 

 inwards a projecting corner, each with 3 small apical bristles. Colour grey- 

 ish white, semipellucid. Length of adult female 5 mm, of male 4 mm. 



Remarks. - This is the only as yet known species of the genus, and 

 of the indigenous Phoxocephalidse the only form provided with distinctly 

 developed visual organs. 



Occurrence. The species would seem to occur along the whole coast 

 of Norway, in moderate depths from 20 to 100 fathoms, muddy bottom. The 

 most southern locality where I have met with it, is Farsund, the most nor- 

 thern, Vadso. In the Trondhjemsfjord, I collected it last summer rather abun- 

 dantly, in a depth of about 100 fathoms. 



Distribution. - Jan Mayen (Norw. North Atlantic Exped.), Greenland 

 (Hansen) ; coast of France (Chevreux).

Body rather stout, subfusiform, moderately compressed. Hood of 

 cephalon evenly vaulted, not carinated nor defiexed at the tip. Coxal plates 

 rather large and provided on the distal edge with a number of strong plu- 

 mose setse; 4th pair very broad in their outer part, forming posteriorly, be- 

 low the deep emargination, a large rounded lobe ; 5th pair with the posterior 

 lobe rather deep and obliquely truncated at the tip, bearing a few plumose 

 setse at the inferior corner. Eyes in all known species wholly wanting. 

 Superior antennse with the 1st joint of the peduncle very large and provided 

 at the end interiorly with a group of large penicillate auditory bristles, 

 penultimate joint slightly expanded distally, and bearing on the posterior 

 edge a number of strong plumose setse. Inferior antennse scarcely longer than
