old and new Amphipoda. 211 
the wrist about equals the second joint in length and breadth, 
it is adorned with long feathered set on the front and shorter 
groups on the hind margin ; the hand, which is considerably 
shorter than the wrist and narrower, though not extremely 
so, is similarly furnished; its palm has a single denticulate 
excavation between the point where the palmar spine is inserted 
and the tooth adjoining the hinge of the finger ; the latter does 
not overlap the palm, and appears to have but one denticle on 
its inner margin. In the female the second joint carries some 
very long feathered setz on the front, and this is the case also 
with the fourth joint. ‘The wrist is not quite so long as the 
hand, proximally very narrow, but distally widest of “all the 
joints, fringed with long feathered sete on the front and 
shorter sete on the back of the widened part. The long and 
rather narrow hand is similarly furnished, but with its width 
little varying throughout. The small finger just fits the 
convex palm. 
First Perwopod.—The fourth joint is ornamented on the 
front margin with two slightly separated series of long 
plumose sete. ‘The marsupial plates are comparatively 
elongate. 
Second Perwopod.—As in some other species within this 
group of genera, this pair of limbs is less setose than the 
preceding. The fourth joint has two series of sete on the 
front margin, but the upper one is insignificant and the lower 
less developed than in the preceding pair. 
The other perseopods are of the usual type. 
Pleopods.—There are two coupling spines and three cleft 
spines to each pleopod. Hach ramus has from fifteen to 
seventeen joints, but the outer is considerably shorter than 
the inner, its joints being smaller than those of its com- 
panion. 
Uropods.—In all three pairs the outer ramus is decidedly 
shorter than the inner. The inner ramus of the second pair 
is stouter than any of the other rami. 
Telson——The length and breadth are equal, the apex 
shallowly rounded, the lateral processes accompanied by five 
spinules apiece. 
Length, without the antennz, about a quarter of an inch. 
The specific name refers to the locality where the specimens 
were found, this being at or near the Cape of Good Hope. 
They were presented to the Copenhagen Museum by Professor 
Studer, and have been entrusted to me for examination by 
Dr. H.J. Hansen. The contents of two tubes had, Dr. Hansen 
informs me, for some reason been put together into a single 
tube. Upon inspection it proved that there were mixed up
