Occurrence. Only ~i female specimens of this 1'orni have hitherto come 

 under my notice. Tiny \\ere found in a sample taken some years ago at Farsund 

 from moderate depth. 



J'age 214. 



Add the following species: 



Nitocra pusilla, G. o. Sars, n. sp. 



l. I'l. 2H, fig. L'I 



-//'' Characters. J^n/ulr. Body less slender than in the other known 

 species, .gradually tapering behind. Rostral projection very small, nodiform. 

 I "rosiime much shorter than the anterior division, last segment comparatively 

 "inall and wanting the spimilose armature found in the other species, the anal 

 opi-rde being quite smooth. Caudal rami of moderate size and quadrangular in 

 form. with the seta- of the outer corner unusually long and pointing straight 

 outward". ;ipic;d setse rather slender and divergent. Anterior antenna} nearly as 

 l"im as the cephalic segment, and composed of 8 sharply defined joint densely 

 <]nthed \\ith slender curved seta and successively diminishing in si/e, terminal 

 I -.-lit e\cr,-ding half the length of the proximal one. Posterior antennre with the 

 outer ramii" \ery small uniarticulate, carrying 3 ciliated setae. Oral parts of 

 normal structure. Kt pair of legs agreeing in structure with those in the other 

 species, the inner ramiis heing distinctly prehensile, with the outer 2 joints 

 inclined and combined scarcely more than half as long as the 1st; apical claw 

 and seta- rather strong. Natatory legs with the inner ramus much shorter than 

 the outer hut distinctly .'J-artirulate. Last pair of legs with the distal joint 

 rounded in form and edged with *i seta\ the outermost of which is unusually 

 Ion- and Blender: inner expansion of proximal joint narrow linguiform and ex- 

 tending somewhat he\ond the middle of the distal joint, marginal seta? in 

 numher, the outermost hut one the longest. Ovisac of moderate si/e oval in form. 



1 (lour not yel ascertained. 



LenL'tli of adult female 0.5(1 mm. 



Remarks. This form differs from the other known species in the less 

 -lender form of the hody and in the absolute want of the usual spinulous arma- 

 ture of the last caudal segment. Otherwise j{ agres pretty well in all essential 

 characters assigned to the present -eiius. It is of smaller si/e than any of the 

 hitherto known specie-.
