marginal seta; inner expansion of proximal joint rather narrow and extending 

 about to the middle of the distal joint, outer apical seta comparatively short 

 and stout, spiniform. 



Colour of the living animal not yet ascertained. 



Length of adult female 0.47 mm. 



Remarks. In its general appearance this form looks not unlike E. 

 brevirostre G. O. Sars, from which species it may however at once be distin- 

 guished by the much shorter caudal rami, and more particularly by the very 

 different structure of the last pair of legs. It is also of rather inferior size. 



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

 come under my notice. It was picked up from a sample taken at Korshavn 

 from a depth of about 30 fathoms. 



Gen. Pseudobradya, G. O. Sars. 



Remarks. This genus was established in the year 1911 by the present 

 author, to comprise some species referred by Scott to the genus Bradya of 

 Boeck, but differing from that genus in several points, both as regards the 

 outward appearance and the structure of some of the appendages. Seven 

 species of this genus have been described in Vol. V of the present work, and 

 I am now enabled to add no less than 10 species, all of them new to science. 

 The total number of Norwegian species is thereby increased to 17 in all. 



22. Pseudobradya digitata, G. O. Sars, n. sp. 



(PI. XIX). 



Specific Characters. Female. Body moderately slender, with the 

 anterior division only slightly dilated in the middle. Cephalic segment much 

 shorter than the exposed part of the trunk, equalling about in length the 3 

 succeeding segments combined; rostral plate short and somewhat deflexed, with 

 the end obtusely rounded. Urosome attaining in length about 3 /4 of the 

 anterior division and slightly tapered behind; genital segment, of moderate 

 size; anal segment about half the length of the preceding segment and slightly 

 incised behind in the middle. Caudal rami somewhat longer than they are 

 broad at the base and only slightly divergent, apical setae not much elongated. 

 Anterior antennae very short and stout, though apparently composed of 6 joints 

 clothed with strong curved setae. Posterior antennae with the inner ramus rather 

 strongly built, outer one extending almost as far as the inner, and distinctly
