peduncle shorter than the 2nd. 1st pair of legs less robust, with the penultimate 

 joint fully as long as the 2 preceding joints combined; 2nd pair with the termi- 

 nal joint narrower, and carrying a smaller number of spines. Uropoda with the 

 rami less unequal, the inner one with only a limited number of spinules, the 

 outer one but scantily setiferous. Colour whitish. Length of adult female scarcely 

 exceeding 5 mm., that of male about the same. 



Remarks. This species, first described by Sp. Bate, is very closely allied 

 to the preceding one, though on a closer examination, it is easily distinguishable by 

 the rather different armature of the anterior edges of the carapace. It is also 

 much inferior in size. The Eudorella inermis of Meinert is undoubtedly the adult 

 male of this species. 



Occurrence. Along the south and west coasts of Norway this form is far 

 from being rare, occurring not infrequently in moderate depths, from 6 to 30 

 fathoms. The most northern locality in which I have observed it, is the Lofoten 

 Islands; farther north, off the Finmark coast, I have never met with it, and its 

 foreign distribution also shows it to be evidently a more southern form than the 

 preceding species. 



Distribution. British Isles (Sp. Bate), Kattegat (Meinert), Heligoland 

 (Ehrenbaum), Mediterranean at Naples and Spezia (the present author).

Eudora hirsuta, G. O. Sai-s, Undersogelser over Christianiafjordens Dybvandsfauna, p. 43. 



Specific Characters. Body extremely slender and elongated, with the in- 

 teguments rather densely hairy. Carapace with the anterior edges coarsely den- 

 ticulate throughout their whole length, and in the upper part clothed with nume- 

 rous stiff, anteriorly curving bristles, exhibiting, moreover, below the middle a 

 well-marked, though rather small sinus; antero-lateral corners not produced. 

 Carapace of (young) male with the anterior edges unarmed, and without any di- 

 stinct sinus. Superior antennae about as in E. truncatula. 1st pair of legs com- 

 paratively more robust, with the penultimate joint scarcely longer than the ante- 

 penultimate one; 2nd pair with the antepenultimate joint unusually elongated 

 and narrowed, last joint comparatively short. Uropoda resembling in structure 

 those in E. truncatula, but having the apical spine of the inner ramus well de- 

 fined at the base. Colour whitish. Length of adult female 5 mm. 



Remarks. This form is about same size as E. truncatula, and may 

 easily be confounded with that species. On a closer examination, however, it is 

 found to differ in the still more slender and elongated form of body, and
