A young male specimen was collected at Elphinstone Island. 

 It is only 21 millim. long, whereas adults of the species attain to 

 double tbe 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 o£ 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 antennge. 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 difierent 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. 



Gelia earinicauda has hitherto been recorded from Hongkong 

 and from North Australia ; so I conclude that it is distributed 

 throughout the whole Malayan Archipelago.
