Colour whitish, pellucid. 



Length of the specimen examined 1.12 mm. 



Remarks. The above described form is evidently referable to the large 

 species recorded by Scott as A. exilis and observed by that author in both 

 sexes. Mr. Scott states the length of the adult female to be no less than 

 1.40 mm., and the present form accordingly grows to a size far exceeding 

 that in any ot the other known species of Ameira. 



Occurrence. A solitary male specimen only of this form has as yet 

 come under my notice. It was captured at Riser from a depth of about 

 20 fathoms. 



Distribution. Scottish coast (Scott). 



Gen. Parameira, G. O. Sars. 



Remarks. Of this genus 4 well-defined species have been recorded 

 by the present author, 3 from the Norwegian coast and one from the Polar 

 Islands North of Grinnels Land (2nd Fram Expedition). Two additional species, 

 both of which have been previously observed by Scott, will be described below.

Specific Characters. -Female. Body comparatively short and robust, 

 with the 2 chief divisions rather sharply marked off from each other. Cephalic 

 segment about the length of the 2 succeeding segments combined and evenly 

 rounded in front, rostral projection inconspicuous. Urosome much shorter 

 than the anterior division and almost of equal width throughout; genital 

 segment large, exceeding somewhat in length the 2 succeeding segments com- 

 bined; last segment scarcely shorter than the preceding one, with the anal 

 opercle considerably prominent and narrowly rounded at the end. Caudal rarni 

 very small and remote from each other; apical setae of moderate length. An- 

 terior antennae comparatively short and stout, not attaining the length of the 

 cephalic segment, 2nd joint only slightly longer than it is broad. Posterior 

 antennae with the outer ramus very small, uniarticulate, carrying 2 short setae, 

 the one apical, the other lateral. Oral parts normal. 1st pair of legs with 

 the inner ramus considerably longer than the outer, its 1st joint rather dilated
