first 2 segments of mesosome somewhat widening in front, the 4 succeeding ones<br />

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

cluding the telson, about the length of the last 2 segments of mesosome combined,<br />

and slightly widening behind. Eyes wholly absent. Superior<br />

tlagellum about the length of the peduncle, and 8-articulate ;<br />

antennse with the<br />

inferior antennse a<br />

little longer than the superior, with the flagellum not attaining half the length of<br />

the peduncle, and composed of about 10 articulations rapidly decreasing<br />

in size<br />

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

a rounded expansion outside, palmar edge occupying the whole inner side, evenly<br />

concave, and fringed with short spines, dactylus long and curved, impinging against<br />

the posterior, produced corner of the palm. Propodos of the 2 succeeding pairs<br />

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

Last pair of legs smaller than the 3 preceding ones. 1st pair of pleopoda with<br />

the inner plate strongly dilated in the middle, and tapering distally to an obtuse<br />

point. Uropoda with the inner rainus rather broad, laminar, terminal joint not<br />

attaining half the length of the proximal one, outer ramus short, obliquely cordi-<br />

form, with the edge minutely crenulated and densely fringed<br />

with ciliated seta_\<br />

Telson oblong, Imguiform, with the tip narrowly rounded, and clothed with slender<br />

bristles. Colour greyish brown, with dark brown ramifications on the sides of<br />

the cephalon. Length of adult female 12 mm.<br />

Remarks. The present species is very nearly allied to the succeeding one,<br />

and has, indeed, by Messrs. Norman and Stebbing, been identified with it, On<br />

;i closer comparison, it is, however, found to differ not only in its much inferior<br />

size and less slender form, but also in the absolute want of eyes,<br />

and in the<br />

far greater indistinctness in the dorsal impressions of the 4th to 6th segments of<br />

the mesosome.<br />

Occurrence. I have only met with this form in 3 places on the Norwe-<br />

gian coast, viz., at the Storeggen bank, at Huso, outside the Sognefjord,<br />

and at<br />

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

to 200 fathoms. Out of Norway, it has not yet been recorded.<br />

Specific Character. Very like the preceding species,<br />

but more than twice<br />

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