edges is more as in C. spatulifrons, but without the tendency to 

 form spinous processes. Our species is much wider than 

 any other. 



Subfamily EUMEDONIN.E. 

 Genus EUMEDONUS, Milne Edivards. 



EUMEDONUS VILLOSUS, sp. noV. 



(Plate xiii., fig. 1.) 



Type-locality. Twenty-five miles south by east of Double 

 Island Point, Queensland, 33 fathoms ; one male, ho lo type. 



Additional locality. Twenty miles north-north-east of 

 Double Island Point, Queensland, 30 fathoms ; one male. 



Measurements. Male holotype, length of carapace to end 

 of rostrum 10.7, length on median line 10, width 10.8 mm. 



Description. Carapace covered for the most part with 

 crowded, forward-pointing granules ; they are absent in the 

 anterior middle portion, which is clothed with long hair. Hind 

 part of carapace depressed, especially in the line of the gastro- 

 cardiac suture. Longitudinal impressions limiting the meso- 

 gastric and anterior cardiac region deep. Rostrum short and 

 broad, ending in two broad, arcuate lobes separated by a 

 narrow emargination. 



Chelipeds rough like the carapace, the right one the larger : 

 they are lobed and spined as follows : a broad lobe on the 

 inner margin of the ischium and another on the inner margin 

 of the merus in its proximal half ; merus proximally carinate 

 above, carina high and faintly bilobed ; a short, stumpy, erect 

 spine at distal end of merus ; a large, curved spine at inner 

 angle of wrist ; two large serrations occupy the upper margin 

 of the nianus. A reddish-brown colour covers the immovable 

 finger and the distal half of the dactylus, except the tips. 



Legs cristate along upper margin of merus, and feebly so on 

 upper margin of carpus and propodus of last two pairs. The 

 crests have an uneven edge, ending in the merus of the first 

 three pairs, in a short distal tooth above, and ha vino; a 

 tendency to form a shallow tooth at the middle of the same 

 crest. Legs sparingly long-hairy. 



Ventral surface of body granulate : abdomen nearly smooth 



Relationships. Resembles E. granulosus McGilchrist. 26 but 

 differs as follows : the carapace is shorter ; granules present in
