ceeding segments combined; anal segment shorter than any of the preceding 

 ones, and broadly emarginated behind in the middle. Caudal rami compara- 

 tively small, being scarcely longer than they are broad; apical setae rather 

 slender. Anterior antennae comparatively shorter than in the preceding species, 

 and only composed of 5 joints. Posterior antennae with the outer ramus 

 somewhat shorter than the inner and very narrow, being composed of 3 joints, 

 the first 2 very small. Anterior lip with a very conspicuous, almost rectangular 

 protuberance in front. The other oral parts, as also the natatory legs, of 

 normal structure. Last pair of legs comparatively small; distal joint narrow 

 quadrangular in form and divided at the end into 3 well-defined and nearly 

 equal lobes without any spinulose clothing, marginal setae rather slender and 

 exhibiting the usual relation in length; appendicular bristle attached at some 

 distance from the base of the joint and accompanied outside by a small 

 spinule; inner expansion of proximal joint somewhat curved and not extending 

 as far as the distal joint, apical setae, as usual, rather unequal in length. 



Colour of the living animal not yet ascertained. 



Length of adult female 0.56 mm. 



Remarks. This species is of still smaller size than the preceding one, 

 from which it moreover at once is distinguished by the much shorter and 

 stouter body. The shape of the anterior lip and that of the last pair of legs 

 are also rather different. ^ 



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

 were obtained from samples taken at Riser and Korshavn from depths ranging 

 from 30 to 60 fathoms. 



28. Pseudobradya pulchella, G. O. Sars, n. sp. 



(PI. XXIV, fig. 1). 



Specific Characters. Female. Body comparatively short, subfusiform 

 in shape, with the anterior division conspicuously dilated in the middle. Integu- 

 ments rather firm and very glossy. Cephalic segment exceeding in length the 

 exposed part of the trunk, and gradually narrowed in front; rostral plate not 

 much prominent and, seen from above, obtusely rounded at the tip. Urosome 

 slightly exceeding half the length of the anterior division and rapidly tapered 

 behind; genital segment about the length of the 2 succeeding segments com- 

 bined; anal segment small and narrowly incised behind in the middle. Caudal 

 rami quadrangular in form, and scarcely longer than they are broad, each with 

 a well-marked keel along the dorsal face; apical setae of moderate length.
