AUSTRALIAN MALACOSTEACA. . 45 



Carapace glabrous, narrow, very convex, tabulated in front 

 only ; lobules not very prominent and separated by broad sulci. 

 Surface of the carapace and of th'e limbs completely covered 

 with close-set tubercles, each in turn covered with minute 

 granular points. Antero-lateral borders very convex, obscurely 

 divided into four lobes. Postero-lateral borders very concave. 



Port Denison ; Port Stephens ; Port Jackson. A widely 

 distributed species.

Actcea calculosa, A. M.-Edw., Nouv. Arch, du Mus., t. i., 

 p. 276, pi. xviii., fig 3. 



Carapace glabrous, moderately broad, slightly dilated in front, 

 flat behind, tabulated only in front ; lobules not very prominent. 

 Surface covered with large depressed granules becoming obsolete 

 behind. Antero-lateral borders imperfectly divided into four 

 rounded lobes. Postero-lateral borders straight. Eront pro- 

 minent, and excavated in the middle. Anterior legs short, 

 sub-equal, rounded above and covered, as well as the wrist with 

 large tubercles. Eingers granular only at the base, short, black 

 with white-tips. Ambulatory legs short, strong, and compressed ; 

 third joint with the upper border acute and slightly denticulated. 

 Eourth and fifth joints tubercular. [A. Milne-Edward's.] 



Specimens from Port Denison in the Australian Museum are 

 distinguished from those described and figured by Milne- Edwards, 

 by having the upper borders of the third joint of the ambulatory 

 limbs much more strongly dentate, especially towards the distal 

 extremity, and by having the granules on the succeeding joints 

 produced and acute. The granules are surrounded each by 

 radiating punctations. This species is very closely allied to 

 A. granulata. 



72. Actaea afflnis. 



Actxodes qffinis, Dana, U.S. Explor. Exped., Crust., i., p. 197, 

 pi. xi., fig. 3 ; A. M.-Edw., Nouv. Arch, du Mus., t. i., p. 263. 



Like the tomentosus in areolets, but the cardiac areolet nearly 

 bisected ; carapace a little narrower, more minutely granulous, 

 sparingly tomentose. Antero-lateral margin 4-dentate. Finger
