Posterior antennae with the distal joint fully as long as the proximal one, apical 

 spines comparatively short; outer ramus extending nearly to the end of the distal 

 joint. Mandibular palp with the basal part obliquely expanded and provided with 

 3 strong plumose setas, both rami very small and imperfectly defined at the base, 

 each with only 3 short, thick setse. Posterior maxillipeds comparatively short 

 and stout, basal joint thick, with a strong plumose seta at the end anteriorly, 

 hand oblong oval in form, with a similar though shorter seta beyond the middle of 

 the palmar edge, dactylus thin and slender. 1st pair of legs with the inner ramus 

 about the length of the outer, distal joint a little longer than the proximal one. 

 Inner ramus in 2nd pair of legs extending considerably beyond the outer, in 3rd 

 pair of about same length as this ramus. in 4th pair much shorter. Last pair of 

 legs each forming an irregular lamella divided at the end by an angular incision 

 into 2 unequal setiferous lappets, the outer one, representing the distal joint, short 

 triangular in form and edged with 5 setse of moderate length, the inner one much 

 more prominent, linguiform in shape, and carrying likewise 5 setse, 2 on the tip 

 and 3 on the inner edge, inner apical seta much longer than the others. 



Male unknown. 



Colour not yet ascertained. 



Length of adult female 0.55 mm. 



Remarks. In the compact appearance of the body, the prominent rostrum, 

 the short, curved, densely hirsute anterior antennae, and the very long, dark- 

 coloured caudal setae, this form somewhat reminds of the species of the genus 

 Longipedia Glaus. A closer examination proves it, however, to be in reality very 

 different, and to be unquestionably referable to the present family as here defined. 



Occurrence. Only 2 female specimens of this form have hitherto come 

 under my notice. They were found in a sample -taken at Farsund, south coast 

 of Norway, from a depth of about 30 fathoms, sandy mud. 



Gen. 80. FultOnia, Scott, 1902. 



Generic Characters. Body subcylindrical in form, with all the segments 

 sharply marked off from each other and edged with slender spinules. Rostrum 

 almost obsolete. Genital segment in female distinctly subdivided; last segment 

 comparatively large. Caudal rami of moderate size. Anterior antenna rather 

 fully developed, 7-articulate, and edged with short, thick ciliated setas. Posterior an- 

 tennae comparatively small, with the proximal joint imperfectly subdivided; outer ramus
