167. Ocypoda Macleayana. 



Ocypoda Macleayana, Hess, Archiv fin* Naturg., Band xxxi., 

 p. 143, pi. vi., fig. 8 (18G5). 



Upper orbital border but slightly curved, almost straight. 

 Cornea at the end of the peduncle overhung by a process of the 

 latter. Anterior legs very small, hands smooth, fingers finely 

 toothed ; dactyli of the four posterior feet very long. Colour 

 bright yellow, the thorax darker and spotted, each joint of the 

 abdomen with two red spots ; the legs with dark bands. [Hess.] 



Sydney (G-ottingen Museum). 



Dr. Hess' description and figure would apply very well to the 

 common New South Wales species of Ocypoda, but that in the 

 latter the hands are never smooth, but granulated. 



168. Ocypoda cordimana. 



Ocypoda cordimana, Desmarest, Consid. sur les Crustacea,

Distinguished from O. ceratophthalma by (1) never having the 

 ocular peduncles prolonged, (2) by having the carapace broader 

 and more convex in the antero-posterior direction and more finely 

 granular, (3) the superior orbital border less oblique, the external 

 orbital angle reaching the line of the base of the front, (4) the 

 anterior limbs more dilated and more finely granular, (5) the hand 

 smooth internally, while that of 0. ceratophthalma has a strong 

 striated transverse crest. 



Tropical coasts. Widely distributed. 



Genus Crossoxotus, A. Milne-Edwards. 

 Cai'apace discoidal and little convex. Front prominent, toothed, 

 and not very broad. Orbits very large and directed forwards. 

 Basal joint of the antenna? situated in the orbital hiatus and not 

 joined to the front. Buccal cavity broad in front, its anterior 

 border with two fissures on each side. Ischium of the external 

 maxillipedes large, its supero-internal angle much prolonged ; 

 the merus very narrow. Chelipedes of the male unequal.
