and about the length of the terminal joint, middle joint comparatively short. 

 The 3 succeeding pairs of legs exhibiting the structure characteristic of the 

 genus. Last pair of legs with, the distal joint exceedingly slender and narrow, 

 sublinear in form, being fully 5 times as long as it is broad, and clothed on 

 both edges with scattered hairs; marginal setae 5 in number, all issuing from 

 the end of the joint; inner expansion of proximal joint triangular in form and 

 carrying 5 strong setae. 



Colour not yet ascertained. 



Length of adult female 0.58 mm. 



Remarks. Though rather inferior in size, the above-described form 

 agress pretty well with the description and figures given by Scott of his 

 Ameira longiremis, and its identity with that species seems to me therefore to 

 be beyond doubt. It is unquestionably referable to the genus Parameira, as 

 defined by the present author, and may be recognised from the other species 

 of that genus by the comparatively robust form of the body, and more par- 

 ticularly by the very slender and narrow distal joint of the last pair of legs. 



Occurrence. Some few specimens of this form, all of the female sex, 

 were picked up from samples taken at Korshavn in depths ranging from 30 

 to 50 fathoms, muddy sand.

Specific Characters,- Female. Body considerably more slender than 

 in the preceding species, with the anterior and posterior divisions of nearly 

 equal length. Last caudal segment a little shorter than the preceding one, 

 with the anal opercle less prominent and evenly rounded at the end. Caudal 

 rami a little longer than they are broad; apical setae of moderate length. 

 Anterior antennae comparatively shorter than in the preceding species, other- 

 wise of a very similar structure. Posterior antennas with the outer ramus, 

 as in that species, very small, uniarticulate, but rather narrower, with both 

 setae issuing from the end. 1st pair of legs resembling in structure those in 

 P. longiremis, inner ramus however comparatively shorter, with all 3 joints of 

 about equal length. Last pair of legs with the distal joint not nearly so 

 elongated as in the preceeing species and oblong oval in form; inner expansion
