the depressions as well as on the elevations, except that the 

 anterior median region is smooth and long-hairy ; lateral 

 spines directed outward and not at all forward ; rostrum more 

 deeply cut ; hands provided with strong teeth above ; merus 

 joints of legs carinate. 



It is singular that the same locality should produce two 

 closely-allied species. The one described below presents the 

 same configuration of carapace as E. villoxiis but many differ- 

 ences in other details. 



EUMEDONUS VICINUS, Sp. HOV. 



(Plate xiii., fig. 2.) 



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

 Island Point, Queensland, 33 fathoms ; one male holotype. 



Measurements. Male holotype, length of carapace to end of 

 rostrum 13.5, length on median line 12.4. width 14.5 mm. 



Description. -- Carapace shaped as in E. villosus, except that 

 the rostrum is longer and is divided at tip into two narrow 

 horns directed forward ; the granules are flatter and squami- 

 form and have a tendency to disappear from the more elevated 

 parts of the posterior half. ( 1 arina on upper margin of merus 

 of cheliped bilobed : lobe on inner margin longer, narrower, 

 and more triangular than in E. villosus ; spine at inner angle 

 of carpus longer, stronger and flatter ; the two spines on the 

 upper margin of the palm are larger and more upstanding. 

 No colour on fingers. There is a thin crest on the upper 

 margin of the carpus and propoclus, as well as on the merus, of 

 the ambulatory legs. Surface of abdomen and most of the 

 sternum coarsely punctate ; anterior sternum granulate and 

 eroded. Abdomen wider than in E. villosus and fringed with 

 hair, having somewhat the appearance of the abdomen of an 

 immature female ; the male appendages are well developed. 



Relationship. The rostrum of this species suggests that of 

 E. zebra, 27 but the branches are not at all divergent, as they are 

 in that species ; the carapace is longer and rougher : the 

 chelipeds are covered with granules and the spines or teeth 

 surmounting the palm are more important ; the legs are 

 similarly (-urinated , but the terminal and the middle tooth 

 above the merus joints are weaker in our species.
