is hardly cmarginate and the second antero-lateral tooth is less prominent than in Micrs's 

 flgui'e. 



This sjiecies is recorded from India (Tuticoriu) by Prof. Henderson, though it is 

 omitted (probably through inadvertence) from Alcock's revision of the Indian 

 Oxyrhyncha. 



Localities. " Channel between reefs, Mer " ; " Mabuiag " (fragmentary specimen).

Five female specimens, showing considerable variation in the relative prominence of 

 the frontal lobes and in some other details. Alcock describes the antennte as "extremely 

 short, reaching only just beyond the tip of the rostrum " ; in our specimens, however, 

 as in the figure of Adams & White, the flagella of the antennae reach far beyond the tip 

 of the rostrum. 



Locality. " Channel between reefs, Mer." 



Xenocarcintjs tuberctjlatus, White. 



Xenocarcinus tuber culatus.i White, Proc. Zool. Soc. 1847, p. 119; A. Milne-Edwards, N. Arch. Mus. 

 Paris, viii. p. 253, pi. xii. figs. 1 a-g (1872) ; Alcock, Journ. Asiatic Soc. Bengal^ Ixiv. (2) p. 192 

 (1895) ; Alcock & Anderson, Illust. Zool. ' Investigator,' Crust, pi. xxxiii. figs. 3, 3 a (1898). 



A single, much damaged, male specimen, agreeing fairly well with Milne-Edwards's 

 fig. 1, save that the carapace is much narrower. 

 Locality. " Murray Island."

The series of this well-knowji species comprises two young males, an adult and a 

 young female, and a " sterile " female in which only the 5th and 6th somites of the 

 abdomen are fused. 



Localities. " Channel between reefs, Mer"; " South of Orman's reef, 5-7 fath."

Two specimens of this very variable species approach most closely to the form named 

 M. cmgustus by Dana, but the rostrum is rather shorter. 

 Localities. " Murray Island " ; " Sabai Channel."
