antenna? transverse. Second joint of the abdomen of the male 

 narrower than the contiguous part of the sternum. 



Fourth joint of the external maxillipedes inserted at the 

 internal angle of the third joint. [_D.] 



Genus Eucrate, De Haan. 

 Carapace arcuate anteriorly, scarcely sloping downwards. 

 Verges of the male inserted on the sternum, and hidden by the 

 abdomen. Anterior legs of the male short, thick. Eyes short. 

 Abdomen of the male 5-jointed, scarcely narrower towards the

147. Eucrate afflnis. A.M. 



Eucrate affinis, Haswell, Proc. Linn. Soc. N.S. W., Vol. vi. 



Carapace smooth, convex ; a faint mesial frontal furrow 

 bifurcated behind so as to bound the anterior portion of the 

 protogastric region ; two slight ridge-like elevations near the 

 antero-lateral border, and another running obliquely parallel to 

 the postero-lateral border. Front straight, faintly notched in 

 the middle. Inner orbital angle acute. Antero-lateral borders 

 with four teeth, each of which is carinated. Anterior legs (in 

 the male) dilated ; arm with a strong tooth above near its distal 

 end, separated distally by a transverse groove from a second 

 lower transverse elevation ; wrist with a small tooth at the distal 

 and internal angle, very hairy externally ; hand smooth, with a 

 longitudinal ridge close to the inferior border, and two rounded 

 elevations between the bases of the fingers. Ambulatory legs 

 long and slender, the three terminal joints hairy above and 

 below. Length fths inch ; breadth inch. 



Off Holborn Island, near Port Denison, 20 fathoms. 



This species is a near ally of E. crenatus, De Haan, but is 

 distinguished from it by the presence of the short ridges on the 

 lateral portions of the carapace, by the shape of the lateral teeth, 

 and the acutencss of the internal orbital angle.
