Remarks. This is another form closely allied to the 2 preceding species, 

 as also to A. typhlops. There are, however, some minor differences both as to 

 the external appearance and the structural details, which make it convenable to 

 keep it apart as a distinct species. The specific name here proposed is derived 

 from the broad lamelliform shape of the caudal rami, in which respect this form 

 is at once recognised from any of the 3 said species. 



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

 found in the same place in which A. confusus occurred.

Remarks. The form described by Prof. Brady 1 ) as Amelra breviremis is 

 in my opinion undistinguishable from the present species. 



Distribution. Polar Islands north of Grinnell Land (2nd Fram Exp.).

Remarks. The characters of this genus must be slightly changed 

 order to comprise the 2 new species described below, which both differ from the 

 type species in the distinctly triarticulate inner i amus of the natatory legs. 



Stenheliopsis latifurca, G. 0. Bars, n. sp. 



(Suppl. PI. 25, fig. 1). 



Specific Characters. Female. Body comparatively short and stout, with 

 the anterior division considerably dilated and of rounded oval form; epinieral 

 plates of the segments laterally expanded and sub-imbricate. Rostral plate large 

 and prominent, with the tip broadly rounded. Urosome almost equalling in length 

 the anterior division, but much narrower, genital segment large and imperfectly 

 divided in the middle, last segment but little shorter than the preceding one and 

 not cleft at the end. Caudal rami comparatively large and broad, equalling in 

 length the last 2 segments combined, and scarcely at all divergent, apical setse
