accompanying seta rather longer than the claw. Natatory legs without any setse 

 inside the outer ramus. Last pair of legs with the proximal part shorter than 

 the distal one, and provided inside with 2 closely juxtaposed setae, distal part 

 carrying 5 strong setse, 2 outside and 3 at the tip, inner edge smooth. Ovisac 

 small, rounded, with a very limited number of ova. 



Mule with the anterior antennae rather strongly built, proximal part con- 

 sisting of 4 well-defined joints, the last globularly dilated, terminal part uniarti- 

 culate, claw-like. Inner ramus of 3rd pair of legs 3-articulate, with the middle 

 joint much the longest and produced at the end outside to a spiniform projection. 

 Last pair of legs with only a single strong seta opposite the outer digitiform 

 process, terminal part with one lateral and 2 somewhat unequal apical setae. 



Colour not yet ascertained. 



Length of adult female 0.45 mm. 



Remarks. This is the first species described, and thus deserves its specific 

 name as the type of the present genus. It is easily distinguished from the other 

 2 species by its long and narrow body, the form of the cephalic segment, and the 

 angular shape of the succeeding segments. 



Oci-iirrcnce. A solitary female specimen of this interesting form was taken 

 some years ago. at Bukken, south-west coast of Norway, from a depth of about 

 20 fathoms. Some few specimens of both sexes were moreover picked up from a 

 sample taken by Mr. Nordgaard in the Salten Fjord, north of the Arctic Circle, 

 and kindly sent to me for examination. 



Distribution. Scottish coast (Scott), Franz Josef Land (Scott).

Specific Characters. Female. Body of a narrow and elongated form some- 

 what similar to that of the preceding species. Cephalic segment, however, very 

 different in shape, exhibiting behind the middle a conspicuous constriction, anterior 

 part triangularly expanded laterally, posterior part sending off to each side a 

 remarkable horn-like process pointing obliquely backwards; rostral projection broadly 

 triangular, with the tip slightly produced and obtusely pointed. The 3 succeeding 

 segments very narrow and rounded laterally; last pedigerous segment somewhat 

 broader. Urosome slender, though somewhat shorter than the anterior division.
