moderate size. Caudal rami comparatively small, though somewhat longer 

 than they are broad; dorsal seta issuing about in the middle from a well- 

 marked knob-like prominence; apical setae of moderate length. Anterior 

 antennae nearly attaining the length of the cephalic segment; 2nd joint rather 

 short, scarcely more than half as long as .the 3rd; 4th joint unusually pro- 

 duced anteriorly. Posterior antennae, as in the preceding species, with the 

 outer ramus replaced by a simple seta. Posterior maxillipeds moderately strong. 

 Natatory legs with the inner ramus uniarticulate, largest on the 1st pair and 

 successively diminishing in size on the succeeding pairs. Last pair of legs 

 with the distal joint very narrow and somewhat tapered towards the end, car- 

 rying 4 setae, the proximal one rather remote from the other 3, which issue 

 from the outermost part of the joint; inner expansion of proximal joint only 

 slightly produced and provided with 2 subequal setae. 



Colour whitish grey. 



Length of adult female 0.73 mm. 



Remarks. The present form may be easily recognised by the unusu- 

 ally coarse dentation of the caudal segments, a character which has given rise 

 to the specific name here proposed. In the structure of the several appendages 

 it seems to come nearest to E. oblongus. 



Occurrence. Some female specimens of this form were obtained at 

 Ris0r in a depth of about 50 fathoms, muddy bottom. It also occurs occasio- 

 nally at Korshavn in about- the same depth.

(PI. LX). 



Specific Characters. Female. Body short and stout, with the anterior 

 division conspicuously broader than the posterior and somewhat depressed. 

 Cephalic segment comparatively large, considerably exceeding in length the 2 

 succeeding segments combined, and gradually somewhat contracted in front; 

 rostral projection only slightly prominent and obtusely pointed at the end. 

 Urosome much shorter than the anterior division and narrower than usual, 

 with the segments uniformly denticulated at the hind edges and the lateral 

 corners not produced; last segment, as usual, of rather large size, with the 

 lateral edges slightly convex and finely hairy; anal opercle quite smooth at 

 the edge. Caudal rami about twice as long as they are broad and only 

 slightly tapered distally; dorsal seta issuing about in the middle; apical setae 

 of moderate length. Antennae and oral parts resembling in structure those in
