Hansen and myself) from different parts of the world and com- 
pared the specimens with the description and figures given by Sars 
(1. c.). As far as I can see Stebbing (1. c.) is right in his syno- 
nymy; but most of the descriptions in the earlier literature are such 
that it is impossible to State whether the species in question are 
the typical form or a variety. I have investigated the following 
specimens, and the result was as follows. 
(No. 1) Spitzbergen VII 1838, 1 ^ 40 mm, determined by 
Krøyer. 1. joint of p 1 is more produced than shown by Sars, 
but in return the 
hind corner of the 
third epimeral plate 
of the metasome is 
not as acute; I have 
not been able to 
find the hairs of the 
hind edge, but it is 
possible that they 
are to be found; on 
the other hånd, there 
are thin spines, al¬ 
most setæ, on the un¬ 
der edge. The hind 
cornerof2. jointofpS 
is not acute enough. 
(No. 2) Kara Sea, Dijmphna-Exp., J', 48 mm (fig. 3), the lar- 
gest of all hitherto known specimens. As the foregoing spec., but 
only 1 hair on the hind edge of third epimeral plate of the meta¬ 
some. The proportions of the antennæ are as in G. loc .; but first 
joint of ant. 1 has on the under side 7 clusters of hairs, thus a 
good character for G. Zaddachi. The hind corner of 2. joint of 
p5 is about as drawn by Sars. 
(No. 3) W. Greenland 61^ 42‘ N., 49^ 46‘ W., 260 m, ringtrawl 
100 m w (Tjalfe-Exp.). 3 28—32 mm. As No. 1. 
(No. 4) E. Greenland, Danmark-Exp. St. 13 C. 1 37 mm, 
from the stomach of a Phoca foetida. As No. 1, but the inner 
ramus of up 3 somewhat too short. The eye is very small, but 
this is perhaps due to some influence from the stomach of the seal.
