 Length of carapace 2 -^th inches ; breadth 3 inches. 



Hob. Port Essington ; collected by Mr. Alex. Morton. This 

 species is much used by the natives for food. 



Neptunus tomentosus, n. s. 



Carapace sligntly convex, finely granular and short-tomentose, 

 shape approaching that of Amphitrite ; breadth about twice and 

 a half the length. Front quadridentate, the teeth rounded, the 

 median rather more prominent and rather narrower than the 

 outer, separated by a deep fissure. Upper orbital margin with 

 two fissures. Antero-lateral borders with eight acute, forward- 

 curved teeth — the last nearly twice as long as the others. Anterior 

 border of merus-joint of chelipedes with three acute teeth ; 

 posterior border unarmed ; carpus strongly ridged, with a very 

 long acute spine internally and two short acute spines externally ; 

 propodos strongly ridged, with one spine at the base and two 

 above the articulation of the dactylos ; fingers of both chelipedes 

 with small, sub-equal teeth.

Eucrate affinis, n. s. 



Carapace smooth, convex ; a faint mesial frontal furrow 

 bifurcated behind so as to bound the anterior portion of the
