96 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
63. Terpousa CaLLIANIRA, n. sp. (Pl. VI. figs. 1-3.) 
(Compared with the type specimen of Telphusa grapsoides, 
White, and with the type specimens of Z. hydrodromus, Herbst, 
T. Jagori, v. Mart., and LT. subquadrata, Gerst., which are pre- 
served respectively in the British Museum and inthe Museum at 
Berlin.) : 
Fifteen specimens (eight 3, seven 2) of this pretty little 
Telphusa are in the Collection; thirteen of which were collected 
in the mangrove-swamps of Kisseraing Island, the two others in 
Sullivan Island. 
This new species is closely allied to the previous species, 
and, I presume, also to 7. angustifrons, A. M.-lidw., a species 
inhabiting Cape York. It belongs to the group in which the 
postfrontal ridge is interrupted not only in the middle by the 
median frontal furrow, but also on each side of the latter in the 
middle, and again near the lateral margins ; so that the two median 
portions are more advanced than, and wholly separated from, the 
lateral, which do not reach the epibranchial tooth. 
The cephalothorax is rather narrow, though broader than long. 
The proportion of the distance between the epibrancbial teeth to 
the length of the cephalothorax (the abdomen being excluded) 
is about 16:14, both in the male and in the female. The 
cephalothorax presents its maximum of breadth immediately 
behind the epibranchial teeth ; so that the anterior half of the 
lateral margins is slightly convex outwards and the posterior 
faintly concave. The upper surface of the carapace is rather 
depressed and flattened; anteriorly it is somewhat convex, and 
the front is almost vertically deflexed downwards. In the female 
the upper surface is a little more convex. 
The front is of moderate breadth; the breadth of its anterior 
margin is in proportion to the distance of the epibranchial teeth 
almost as 6 to 16, so that the front measures a little more 
than a third of the distance of the epibranchial teeth. The 
anterior margin of the front, which is nearly straight, pre- 
sents only a very slight median sinus, and is almost at a right 
angle with the upper margins of the orbits. In 2. hydro- 
dromus, Herbst, however (a species inhabiting the island of 
Ceylon, and closely allied to our Z. Callianira), these angles 
are very oblique and rounded, according to Dr. Hilgendorf, 
who kindly compared for me this species with all the Zel- 
phuseé of the Zoological Museum of Berlin. Dr. Hilgendorf
