AMPHIPODA OF THE SCOTTISH NATIONAL ANTARCTIC EXPEDITION. 485 
but as they are both females of smal] size, and perhaps not fully mature, the identifica- 
tion is not free from doubt. They agree generally with the description of the species 
in Das Trerreich Amphipoda, but appear to differ in the following points :— 
The upper antenna is rather longer and stouter than the lower; the flagellum is 
very small, and consists of one short joint and two, or perhaps three, very minute ones. 
The lower antenna has the fifth joint of the peduncle a little longer than the fourth, 
and both considerably longer than the third ; the flagellum consists of one small joint, 
fcllowed by one or more very minute ones. There are no serrations to be seen on the 
lower antenna, the animal in this point agreeing with the description. 
The mouth parts were not examined. 
The first gnathopod is long and slender, agreeing well with the description. 
The second gnathopod has the carpus as long, and at distal end as broad, as the 
propod. The inner branch of the third uropod scarcely reaches beyond the extremity 
of the preceding uropods ; its upper margin is minutely serrulate ; the outer branch is 
more slender, and is about two-thirds as long. Very minute serrulations are present on 
the inner branches of the first and second uropods also. 
The telson apparently agrees with the description, but could not be fully examined. 
It is perhaps doubtful if this species is really distinct from C. pusilla (Grube), from 
the North Atlantic and the Mediterranean, but the Scotea specimens appear to differ 
from it in the proportions of the joints of the lower antenna, and in the absence of 
serrations on the peduncle. On the other hand, the second gnathopods and the 
uropods agree quite as well, or perhaps better, with C. pusilla than with C. brazer. 
Another species, C. hamifera Kossmann, has been recorded from the Red Sea, but is 
thought to be probably an immature male of C. pusilla. All the three species were 
combined under the name C. pusilla by Datta VALLE in 1893. 
C. brazert was described from the east coast of Australia. I have taken a specimen 
in Otago Harbour, New Zealand, that probably belongs to the same species ; in the 
living animal the eye was red as in C. pusilla.

One imperfect specimen, anterior half of body only ; the length of the whole 
animal would be fully 15 mm. 
This fragment seems to belong, without doubt, to this species; it agrees in the 
peduncles of the antennz and in the narrower basal joints of the third to fifth .
