Remarks. — The character whereby in particular the 
present genus differs from the other genera of Tanaidae. 
is the rudimentary nature of the pleopoda in the female. 
So far, the animal approximates closest the genus HapJocope 
G. 0. Sars; 1 but in that form the said parts constitute 
mere simple, squamiform appendices, whereas in the genus 
Cryptocope they are, notwithstanding their rudimentary 
nature, distinctly biramous. Also in the structure of the 
mandibles, the genus differs very perceptibly from the other 
genera of Tanaidaa. Exclusive of the animal described more 
in detail below, this genus also coni] irises the Norwegian 
species that, as Tanais abbreviatus , I had briefly charac- 
terized on a former occasion, and which, as regards the 
pleopoda, exhibits a relation precisely similar.

Specific Character. — Body about 5 times as long 
as broad, with exceedingly tumid segments, separated one 
from the other by deep instrictions ; in male a trifle more 
slender, particularly in the middle. Cephalic shield bellying 
out very considerably toward the sides, with a somewhat 
flexuous frontal margin. Posterior division of body, in 
female, more slender than anterior, with 5 strong spines 
along the ventral side, and having the last segment ex- 
ceedingly tumid, almost globular; in male, without ventral 
spines, and having the last segment narrower and, posteri- 
orly, triangular-acute. First pair of antennae, in female, 
shorter than cephalic shield, in male considerably longer. 
Chelipeds remarkably powerful, with the band exceedingly 
swollen, and the fingers about of same leugth as the palm, 
terminating in born-coloured points, that cross one another. 
Caudal appendages in female very short, and directed ob- 
liquely inward, with the outer branch one-jointed, the inner 
two-jointed and considerably larger; in male with two and 
three-jointed branches. Colour a, uniform white. Length 
reaching 
Locality. — Stats. 31, 124, 248. 
Remarks. — The present large-sized Tanaid is readily 
distinguished from all other forms by the exceedingly tumes- 
cent segments, separated one from the other by unusually 
deep instrictions, and giving to the body a peculiar monili- 
form appearance. Moreover, from the 2nd species of the 
genus C. abbremata, it may be easily recognized by its far 
greater size, as also by a comparatively less thickset form 
of body.
