5 CARCINOLOGICAL STUDIES. 



with gaping maxillipedes to the genus Hemigrapsus. I am 

 also inclined to refer these forms to different genera. 



The inferior margin of the orbits of the male is entire 

 and appears only very minutely granulated when seen under 

 a strong magnifying-glass. 



The carpopodite of the anterior legs is rounded and 

 unarmed at the internal angle. The hands are quite smooth, 

 but the slightly gaping fingers are provided 

 with a patch of hair externally as well as in- 

 ternally. 



The ambulatory legs are rather slender. The meropodi- 

 tes are armed with an acute tooth at the distal end of 

 their upper margin. The propodites and dactylopodites of 

 the male are tomentose along their inferior margin; the 

 toment has its greatest development on the propodites and 

 dactylopodites of the first pair, and gradually diminishes 

 on those of the other legs. 



This species, on account of its more strongly deflexed 

 front and slightly concave antero-lateral margins , is quite 

 different in appearance from its congeners. 



I give the measurements of the two quoted individuals and 

 of a male type-specimen from Australia of the Paris Museum.
