Hansen and myself) from different parts of the world and com- 
paåred the specimens with the description and figures given by Sars 
(1. 'c.).:As far ås I can see Stebbing (1. c:) is. right in his syne 
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 g 40 mm, determined by 
Krøyer. 1. joint of pl 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 hand, there 
are thin spines, al- 
3 most setæ, on the un- 
der edge. The hind 
cornerof 2. joint ofp5 
is not acute enough. 
(No. 2) Kara Sea, Dijmphna-Exp., g, 48 mm (fig. 3), the lar- 
gest of all hitherto known specimens. As the foregoing spec., but 
.only I 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 å 
good character for G. Zaddachi. The hind corner of 2. joint of 
p5 is about as drawn by Sars. 
(No. 3) W. Greenland 619% 42: N,, 499 46 W., 260 m, ringtraw! 
100 m w (Tjalfe-Exp.)'" 3 3 72832 mm. Ås No. Il. 
(No. 4) E. Greenland, Danmark-Exp. St. 13 C. 1 gg 37 mm; 
from the stomach of a Phoca foetida. As No. 1, but the inner 
ramus of up3 somewhat too short. The eye is very small, but 
this is perhaps due to some influence from the stomach of the seal-
