tapered behind; genital segment, as usual, much the largest; anal segment 

 deeply incised behind in the middle. Caudal rami somewhat produced, 

 exceeding in length the anal segment, and rather divergent; apical setae moder- 

 ately slender. Anterior antennae comparatively smaller than in the preceding 

 species and only composed of 6 joints. Posterior antennae, oral parts, and 

 natatory legs exhibiting the usual structure. Last pair of legs likewise quite 

 normally developed; distal joint of moderate size and quadrangular in form, 

 with the marginal setae rather unequal, the middle one being much the longest, 

 the outermost the smallest; inner expansion of proximal joint not much pro- 

 duced, and having the apical setae moderatelyj slender and rather unequal. 

 Ovisac comparatively small. 



Colour whitish grey. 



Length of adult female 0.61 mm. 



Remarks. The present species exhibits in the general shape of the 

 body a perplexing resemblance to B. furcata, and may at the first sight easily 

 be confounded with that species 1 On a closer examination, it is however found 

 to differ in the somewhat less produced caudal rami, as also in the structure 

 of some of the appendages, especially that of the last pair of legs. 



Occurrence. One or two specimens only of this form have as yet 

 come under my notice. They were taken at Ris0r in a depth of about 60 

 fathoms, muddy sand. 



Gen. Halophytophilus, A. Brian, 1918. 



Generic Characters. Body somewhat resembling in its general shape 

 that in the genus Bradya, though having the two chief divisions less sharply 

 marked off from each other. Cephalich segment produced in front to a strongly 

 chitinised recurved rostrum. Urosome very slender and attenuated. Anterior 

 antennae comparatively strong, 6-articulate, with the terminal joint unusually 

 prolonged. Posterior antennae with the outer ramus very small, inner one 

 well developed, with the distal joint coarsely spinous. Mandibles with the 

 masticatory part narrowly exserted, palp comparatively large, though having 

 the rami short and stout. Maxillae not examined. Anterior maxillipeds with 

 the 2nd basal joint remarkably long and narrow, forming with the 1st a sharp 

 genicular bend. Posterior maxillipeds apparently 4-articulate, with the penulti- 

 mate joint rounded and fringed with ciliated setae, terminal joint armed at the 

 tip with claw-shaped spines. 1st pair of legs with the inner ramus sub-pre-
