SPOLIA ZEYLANICA. 
and not uncinate finger approach the second gnathopods, but 
in the spiny armature of the ante-penultimate joint and the 
greater proportionate length of that which precedes it they are 
nearer to the three following pairs. These have the penultimate 
joint slightly curved and distally bulging, with the finger strongly 
hooked, but this hook is not, as it is in T. cavolinii , armed inside 
with a comb of denticles. 
The pleopods differ in armature markedly from those of the 
species compared, for there the branch which is the smaller and 
attached to the upper part of the stem has its outer margin well 
fringed with setae, whereas in the new species this margin has a 
single seta near the base. Both species alike have a little tooth-like 
spine at the apex of this branch. 
The uropods are four-jointed. On one side the penultimate 
joint is decidedly the largest of the four, but its superiority in 
length is less marked in the other member of this pair of append¬ 
ages. 
The colour was light mottled brownish gray in spirit. The 
length from front of head to end of telson was 3 mm. 
The specific name, from a Greek word meaning “ lover of 
comrades,” alludes to the discovery of this little animal in the great 
association of pile-dwellers which Dr. Willey has brought to light. 
From other members of the genus which have four-jointed 
uropods the new species is readily distinguished. T. robustus , 
Moore, and T. testudinicola , Dollfus, have the pleon distinctly six- 
segmented, and the bands of setae on the first two of those segments 
wanting or feebly represented. The second of these has the front 
of the head sharply produced. In T. grimaldii , Dollfus, the 
cephalic segment is almost (in the figure quite) as broad as long. 
In T.clxevreuxi , Dollfus, the first joint of the uropods is decidedly 
the longest.
