lanochirus, A. M.-Ed wards * ; but the spiniform teeth of the antero- 

 lateral margins are much more prominent, the anterior margin of 

 the merus of the chelipedes is not tuberculated, the ambulatory legs 

 not spinulose. In a specimen from the Philippines (Cuming) that 

 I refer to G. melanochirus, in the British Museum, the hands of the 

 chelipedes in the male are much more robust, and the merus and 

 two following joints of the ambulatory legs strongly spinulose, not 

 only on the outer margins, but also on the posterior surface. From 

 most of the other species of this genus it is distinguished either by 

 the different coloration of the hands (fig. a) and the form of the 

 antero-lateral marginal teeth, or the absence of spinules on the 

 ambulatory legs. 



Ohlorodopsis areolatus (Milne-Edwards), a species originally de- 

 scribed from New Holland, and referred to in the second part of 

 this Report, is easily distinguishable by the form of the frontal lobes 

 and antero-lateral marginal teeth. 



49. Etisus IsBvimanus, RandaU. 



A male of this very common Oriental species was obtained at 

 Port Molle, on the beach (No. 95).

 Hebrides {J. Macgillivray) ; Samoa Islands {Rev. S. J. Whitmee) ;

Dr. F. Hilgendorf t has already referred to the synonyma of 

 K IcBvimanv^, which ranges in a westerly direction to the Eed Sea
