found near the anterior margin. The inner surface of the fingers 

 is concave and perfectly smooth, as in G. annulipes. The ambula- 

 tory legs are somewhat less slender than those of G. annulipes, 

 especially when the meropodites of the last pair of legs are 

 compared.

The upper surface of the carapace of these specimens (preserved 

 in alcohol) is dark bluish and marked with lighter transverse 

 stripes and spots ; in some specimens the carapace appears light 

 green, and ornamented with transverse lines and spots of a 

 darker colour. The larger hand appears uniformly yellowish. 



Gelasimus triangularis, which is distinctly separated from the 

 other Indian species of this group, viz. G. annulipes, G. lacieus, 

 G. Gaimardi, G. cMorophtJialmtts, and G. LatreiUii, by the shape 

 of its carapace and the structure of its larger hand, has hitherto 

 been recorded only from the stores of New Caledonia. It will 

 doubtless, however, be found to occur throughout the whole 

 Malayan Archipelago.

Seven fine specimens (4 d , 3 $ ) were collected in the Mergui 

 Archipelago. 



This species is closeij allied to MacropTithahius depressus, Eiipp., 

 and M. japonicus, de Haan, but it may be easily distinguished by
