of 400 fathoms. Subsequently I have found it occasionally
off the coasts of
Xordland and Finmark, in depths ranging from 100 to 150 fathoms. Out of
Norway it has not yet
been recorded.
Gen. 3. lanlPOpSiS, G. 0. Sars. n.
Generic, Characters. General habitus that of Ian int. Lateral parts of
the segments but slightly expanded, not laciniate. Eyes well developed. Superior
antennse comparatively small, with the rlagellum only composed of a limited number
ot articulations. Inferior antennae of moderate length, being much more strongly O \J
built in male than in female; squamiform appendage in both sexes very small,
but distinctly denned. Maxillipeds with the 2nd and 3rd joints of the palp very
much expanded, laminar. Legs comparatively short and thick, with the dactylus
bi-unguiculate ; 1st pair in female not differing at all from the others, in male, on
the other hand, remarkably developed, prehensile, much longer than any of the
other pairs, with the carpal joint fusiformly dilated. Middle piece of male oper-
culum remarkably dilated at the tip. Uropoda of same structure as in lauint,
but much shorter.

Remarks. This new genus is founded upon the form recorded by the
author as lanlra breviremis. A closer examination of this form, and more
especially of the male, has revealed some characteristic features, which make it
advisable to separate it generic-ally from lanint, and such a separation was also
opined by Dr. Bovallius to be necessary. It is especially the structure of the 1st
pair of legs which is characteristic. In the female, this pair,
unlike what is the
ease in lanira, do not differ in any manner from the others legs, being, like these,
ambulatory. On the other hand, this pair assumes in the male a quite extra-
ordinary development, being pronouncedly prehensile, and much larger than any
of the other legs. Moreover, the structure of the superior antenna- and the
maxillipeds is slightly different, as also the middle piece of the male operculum.
The genus contains as yet but a single species, to be described below.
