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. lacteus, 
G. Gaimardi, G. chlorophthalmus, and G. Latreilli, by the shape 
of its carapace and the structure of its larger hand, has hitherto 
been recorded only from the shores of New Caledonia. It will 
doubtless, however, be found to occur throughout the whole 
Malayan Archipelago.

This species is closely allied to Macrophthalmus depressus, Riipp.,
