distal joint oval in form and regularly trilobate at the end, setae increasing in 

 length inwards; inner expansion of proximal joint rather narrow and scarcely 

 extending as far as the distal joint, apical setse rather unequal, the inner one 

 being much the longer; appendicular bristle of moderate length, and issuing at 

 the junction between the proximal and distal joints. Ovisac oblong oval in form, 

 enclosing comparatively large ova. 



Colour yellowish grey. 



Length of adult female 0.63 mm. 



Remarks. This form may be easily distinguished from the other members 

 of the present family by the very prominent hyaline rostral plate, the remarkably 

 smooth and shining surface of the body, and the structure of the several ap- 

 pendages. 



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

 sex, were taken last summer at Farsund in depths ranging from 30 to 50 fathoms.

Specific Characters. Female. Body moderately slender, with the anterior 

 division oblong oval in form and somewhat depressed. Cephalic segment about 

 the length of the 3 succeeding segments combined, rostrum not very prominent, 

 and obtusely rounded at the end. Urosome scarcely more than half as long as 

 the anterior division and much narrower, hind edges of the segments finely spin- 

 ulose ventrally and laterally; last segment rather small. Caudal rami very short, 

 being broader than they are long, tpical setse slender and elongated, the inner
