AUSTRALIAN MALACOSTRACA. 53 



legs covered with granular nodosities disposed in regular series. 

 Ambulatory legs slender and without spines above. 



Ilolbom Island, near Port Denison, on coral reef. Originally 

 found in New Caledonia. 



There are some differences between the specimen from Port 

 Denison and the New Caledonian species described by Milne- 

 Edwards ; thus the front is more concave in the centre, and the 

 anterior margin of the buccal cavity is without the strong beading 

 shewn in Milne-Edwards' figure ; but the correspondence in all 

 other points is too close to permit of their being regarded as 

 distinct species. 



Crenus Menippe, De Haan. 



Antero-lateral margin shorter than the postero-lateral. Basal 

 joint of the external antennae short, neither reaching the front 

 nor a process of the front. Abdomen of the male seven- jointed. 



85. Minippe Legouilloui.

 Swan River (Brit. Museum). 

 I have not seen the description of this species. 



Sub-Family Chlorodince. 



Internal antennae transverse. External antennae firmly fixed 

 at the base, the flagellum rarely excluded from the orbit. Inter- 

 orbital region rather broad. Fingers spoon-excavate. [Z>.] 



Crenus Etisus, Leach. 



Internal orbital hiatus occupied by a process of the base 

 of the antennae, excluding the flagellum from the orbital 

 cavity. Front broad, lamellar ; antero-lateral borders strongly 

 toothed. [Z>.] 



86. Etisus dentatus.
