CUUSTACEA OF TUE MEEGUI AECHIPELAQO. 45 



Eurycarcinus natalensis, Krauss, and E. Qrandidieri, A. M.- 

 Edw., the second lateral tooth is the largest of all, and in E. inte- 

 grifrons, d. M., the two anterior antero-lateral teeth are of equal 

 size.) The subhepatic region is minutely granular and hairy. 

 The endustome is faintly ridged on each side. The sternum of the 

 male is minutely punctate when seen uiider a magnifying-glass, 

 and the postabdomen is seven-jointed. 



The chelipedes are very unequal in size, and in this specimen 

 the right is the largest. As in the case of the ambulatory legs, 

 they seem to agree in all respects with those of the Zanzibar 

 specimens described by Milne-Edwards. The ambulatory legs 

 are provided along their upper and under margins with some 

 hairs, few in number on the meropodites, but more numerous 

 and dense on the two terminal joints, which moreover bear a 

 close down ; and finally the carpopodites of the chelipedes 

 are armed with a small rather acute tubercle at their internal 

 angle. As in specimens from Zanzibar, the outer surface of the 

 hands is marked with numerous small red spots. 



This very rare species has hitherto been known only from the 

 shores of Zanzibar.

One fine female specimen was collected at Sullivan Island. It 

 has the cephalothorax 57 millim. broad and 41 millim. long. 



Ozius tuberculosus had been previously recorded from the 

 Mauritius, the Nicobar Islands, and New Caledonia. 



Grenus Epixanthus, Heller. 



Although scarcely generically distinct from Ozius, the genus 

 Epixanthus may be retained for those species the cephalothorax 

 of which is more enlarged, more depressed and flattened, and 

 in which the fingers of the smaller chelipede are very slender 

 and in contact with one another over their whole length. The 

 genus is represented in the Indo-Pacific region as well as on 

 the shores of West Africa. The former region is inhabited by 

 Epixanthus fronlalis, M.-Edw., E.dentatus, White, and E. cor-
