35. Bradya congenera, G. O. Sars, n. sp. 

 (PI. XXVIII, fig. 1). 



Specific Characters. Female. Body of the usual obpyriform shape, 

 the anterior division being somewhat broader in front than behind. Cephalic 

 segment about the length of the exposed part of the trunk, and slightly con- 

 tracted at the anterior extremity, with the front, seen from above, obtusely 

 truncated; rostral plate rather deflexed. Urosome somewhat exceeding half the 

 length of the anterior division, and gradually tapered behind; genital segment 

 fully as long as the 2 succeeding segments combined; anal segment, as usual, 

 the smallest, though not much shorter than the preceding segment, and broadly 

 emarginated behind in the middle. Caudal rami comparatively short, not nearly 

 attaining the length of the anal segment and somewhat divergent; apical setae 

 very slender. Anterior antennae of moderate size and composed of 8 well 

 defined joints. Posterior antennae, oral parts, and natatory legs resembling in 

 structure those parts in B. typica. Last pair of legs likewise very similar, the 

 mutual relation in length of the setee attached to the distal joint being the 

 very same. Ovisac comparatively small. 



Body of the usual whitish grey colour. 



Length of adult female scarcely exceeding 0.67 mm. 



Remarks. The present form is closely allied to B. typica, exhibiting a 

 very similar structure of the several appendages. It is however of much smaller 

 size, and may, on a closer examination, be distinguished by the comparatively 

 shorter caudal rami and the distinctly 8-articulate anterior antennae. 



Occurren ce. Several specimens of this form have been collected at 

 Riser together with the other species, and it probably also occurs in many 

 other places of the Norwegian coast. As however its specific difference from 

 B. typica has not formerly been recognised, the exact localities cannot at 

 present be stated. 



36. Bradya simulans, G. O. Sars, n. sp. 

 (PI. XXVIII, fig. 2). 



Specific Characters. Female. Body resembling in shape that of 

 B. furcata, being rather short and stout, with the anterior division elliptical 

 in outline. Cephalic segment comparatively large, exceeding somewhat in 

 length the exposed part of the trunk, and gradually contracted anteriorly, with 

 the front, seen from above, narrowly rounded; rostral plate small, deflexed. 

 Urosome about equalling in length 2 , 3 of the anterior division and rapidly
