first 2 segments of mesosome somewhat widening in front, the 4 succeeding ones 

 nearly twice as long as they are broad; last segment very small. Metasome, in- 

 cluding the telson, about the length of the last 2 segments of mesosome combined, 

 and slightly widening behind. Eyes wholly absent. Superior antennae with the 

 flagellum about the length of the peduncle, and 8-articulate ; inferior antennae a 

 little longer than the superior, with the flagellum not attaining half the length of 

 the peduncle, and composed of about 10 articulations rapidly decreasing in size 

 distally. 1st pair of legs with the propodos very large, oval triangular, forming 

 a rounded expansion outside, palmar edge occupying the whole inner side, evenly 

 concave, and fringed with short spines, dactylus long and curved, impinging against 

 the posterior, produced corner of the palm. Propodos of the 2 succeeding jjairs 

 oval pyriform in shape, and armed on the palmar edge with 4 strong spines. 

 Last pair of legs smaller than the 3 preceding ones. 1st pair of pleopoda with 

 the inner plate strongly dilated in the middle, and tapering distally to an obtuse 

 point. Uropoda with the inner ramus rather broad, laminar, terminal joint not 

 attaining half the length of the proximal one, outer ramus short, obliquely cordi- 

 form, with the edge minutely crenulated and densely fringed with ciliated setae. 

 Telson oblong, linguiform, with the tip narrowly rounded, and clothed with slender 

 bristles. Colour greyish brown, with dark brown ramifications on the sides of 

 the cephalon. Length of adult female 12 mm. 



Remarks. — The present species is very nearly allied to the succeeding one, 

 and has, indeed, by Messrs. Norman and Stebbing, been identified with it. On 

 a closer comparison, it is, however, found to differ not only in its much inferior 

 size and less slender form, but also in the absolute want of eyes, and in the 

 far greater indistinctness in the dorsal impressions of the 4th to 6th segments of 

 the mesosome. 



Occurrence. — I have only met with this form in 3 places on the Norwe- 

 gian coast, viz., at the Storeggen bank, at Huso, outside the Sognefjord, and at 

 Hvitingso. In all 3 places it occurred rather sparingly at a depth of from 150 

 to 200 fathoms. Out of Norway, it has not yet been recorded.

Specific Character. — Very like the preceding species, but more than twice 

 as large, and somewhat more slender in form. Cephalon very small and, seen
