Zoogeographical Investigations in Southern Greenland. 297 
men (from St. 121), and received the following reply: “Sie ist offenbar 
neu; leider freilich nur ein 2 juv.; also kann man gar nicht wissen, 
wie die alten ¢ aussehen mégen”. I take this opportunity of expres- 
sing my best thanks to Prof. P. Mayer for his courtesy in the matter. 
I have drawn the grown 9, but as p6—p7 are lacking in this 
specimen, these are here taken from the immature specimen from 
St. 121. 
In point of habit, the present species resembles C. septentrionalis, 
as regards its strong build, but is immediately distinguished from 
this by its spines and warts: The whole of the body, with the exception 
of the two posterior segments of the mesosome, is warty down the back, 
the 2. segment being also slightly warty on the ventral side. Above 
and between the eyes there is a strong spine pointing forward; in front 
of this there are, in the grown 9, a few small warts, and in the young 
2 a slightly smaller spine. The dorsal warts are setose. At the posterior 
end of the cephalon, 1., 2. and 4. mesosome segments, there is a large 
protuberance, and about the middle of the 2.—7. segments of the me- 
sosome two thick spines set as a pair. The eyes are round and colour- 
less. The antennae are of the same length and shape as in the @ of 
C. septentr. but the 3. joint in the peduncle of ant. 1. is slightly longer. 
Pi—p2 nothing particular to remark. The gills are sausage-shaped, and 
there are no spines at their base. P5—p7 of about the same shape as 
in C. septentr., but the 2. joint does not project so much behind. 
No other Caprellid has been taken in Greenland at so great a depth; 
the nearest is Aeginella spinosa, which was taken at 210—225 m. (“Rink’’) 
and also at 167 fathoms. 
At the both stations a number of Hydroidae were taken; there is 
thus but little doubt that the animals must have lived on these. 
Isopoda.

Conspectus p. 229. 
Bredefjord St. 55, 310—330 m., 1 spec. 
The specimen in question lacks the depressions in the back. The 
species has not previously been taken S. of abt. 6614° N. 
92. Gnathia sp. 
Bredefjord St. 45, 430—450 m. an old Praniza. 
Three species of Gnathia in all are known from Greenland (vide 
‘Conspectus p. 230—31), viz.: G. elongata, G. cristata, and G. robusta; the 
Praniza stage of G. cristata however, is not known. The present spe- 
cimen closely resembles that shown by Sars in Norske Nordhavs Exped., 
Pl. 8, fig. 27: a Praniza of G. robusta; I am not certain, however, that 
it really is this species.
