A young male specimen was collected at Elphinstone Island. 
It is only 21 millim. long, whereas adults of the species attain to 
double the length. In both hands the lower margin of the palm 
bears a small acute spine at the base of the immobile finger, the 
latter being scarcely half as long as the mobile finger. The 
ischiopodites of the anterior legs are armed with two spines. 
The meropodites of the legs of the first and second pairs are 
armed with a small spine at their distal ends, and the under 
margins of those of the chelipedes are also somewhat spinulose. 
There is a short spine at the base of the legs of the second and 
third pairs. The antero-lateral margin of the carapace is armed 
with a small spine between the front and the insertion of the 
peduncle of the external antenne. The form of the last post- 
abdominal segment is also distinctive of the species, as it is 
nearly quadrate, and provided with a transverse crest at a small 
distance from the anterior margin, and its posterior margin is 
distinctly narrower than the latter. 
I suppose Gebia hirtifrons, White, to be a different species, 
distinguished by the lower margin of the palm not being toothed, . 
and by a somewhat different form of the terminal postabdominal 
segment, the posterior margin of which has nearly the same 
breadth as the anterior. The terminal postabdominal segment 
of G. maior, de Haan, is also distinctly broader than long. 
Gebia carinicauda has hitherto been recorded from Hongkong 
and from North Australia; so I conclude that it is distributed 
throughout the whole Malayan Archipelago.

144. GEBIOPSIS INTERMEDIA, n. sp. (Pl. XVI. fig. 2.) 
Four adult specimens (2 2, 2 ¢) are in the collection, and 
were found at Elphinstone Island. 
I name this species G. intermedia because in many of its cha-
