AUSTEALIAN MALACOSTEACA. 67 



borders only. Lower orbital border feebly incised externally ; 

 third joint of the external maxillipedes scarcely truncate. 

 Length five lines. [M.-J£.~\ 



Australia (Mus. Paris) ; Port Molle, on coral reefs. (W.A.H.) 



I refer to this species a Pilumnws obtained on the reefs at 

 Port Molle, which conforms pretty well to Milne-Edwards' brief 

 description. The antero-lateral regions of the carapace and the 

 chelipedes are ornamented with numerous granulations. The 

 hairs on the edges of the carapace are not very numerous, but 

 very long (about fths of an inch) ; the merus of the ambulatory 

 legs has a thin entire crest above. This species belongs to the 

 same section of the genus as P. inermis.

Pilumnus tomentosus, M.-Edw., Hist. Nat. Crust., i., p. 418. 



Differs from P. vespertilio only in having granulations on all 

 the lower portion of the hand, and by the character of the hairs 

 which constitute a sort of very short fur ; body blackish brown ; 

 fingers blackish. [M.-E.~\

115. Pilumnus cursor. 



Pilumnus cursor, A. M.-Edw., Nouv. Arch, du Mus., t. ix., 

 p. 244, pi. ix., fig. 4. 



Carapace sub-quadrilateral, little convex, slightly granular and 

 covered with a short pubescence. Regions scarcely indicated. 

 Pront formed of two rounded deflexed and prominent lobes, 

 separated from the orbital angles by a fissure. Antero-lateral 

 borders armed with three sharp spines situated behind the 

 external orbital angle. Postero-lateral borders nearly straight. 

 Anterior legs with long scattered hairs. Large hand, granular 

 above and externally, smooth and glabrous below and near the 

 base of the immobile finger. Small hand entirely covered with 

 hairs and granulations. Ambulatory legs slender and covered 

 with long hairs. [A. M.-JE.]
