continued backwards and inwards as a sharp, finely crenulated 

 crest. The surface of the carapace, especially anteriorly, appears 

 minutely granular under an ordinary lens, its sides behind the 

 points at which the cristiform continuations of the epibranchial 

 teeth subside are marked with oblique sub-parallel corrugations. 

 The four posterior pairs of ambulatory legs are extremely thin ; 

 the posterior flat faces of their meropodites are raised into coarse 

 granulations, while the anterior surfaces remain smooth ; the dacty- 

 lopodites are extremely slender, acute. Chelipedes subequal, dacty- 

 lopodites in contact throughout their entire length with the propo- 

 dites the outer faces of which are smooth and convex ; carpopo- 

 dites furnished internally with a long sharp spine, beneath which is 

 a smaller one ; meropodites corrugated on their posterior surfaces. 

 I am unable to verify Heller's statement that the crest on the 

 latero-anterior margin is smooth in the females.

Telphusa planata is given as a synonym of T. Guerini, M.-Edw., 

 with doubt, although M. Alph. Milne-Edwards' description of the 

 former applies exactly to individuals amongst my series of examples 

 of the latter.

Carapace much broader than long, flattened in the middle pos- 

 teriorly to a line passing through its widest part ; protogastric 

 lobes convex, separated from one another by the narrow for- 

 ward prolongation of the meso-gastric lobe ; meso-gastric fur- 

 row passing into the post-frontal, deeply dividing the two epigas-
