]Not Clorodius Desmarest, 1823 ; de Haan, 1833. 



I am unable to agree with Eathbun and Ortmann as to the 

 necessity for a new name for this genus, and prefer to follow 

 Alcock in considering that Milne-Ed wards's name holds good.

51. Chlorodius barbatus, n. sp. (Plate XLI. fig. 4.) 



Diagnosis: "A small Chlorodius with the areas of the carapace 

 faintly demarked ; chelipeds unequal ; the fingers of the large 

 hand widely gaping, less strongly toothed than in C. Icevissimus 

 Dana 1852, and more hollowed at the tip ; the large hand bearing 

 a tuft of hairs at the base of the fingers on the outside, hiding the 

 proximal part of the fingers ; the first tooth of the antero-lateral 

 edge wanting altogether, and not, as in C. Icevissimus, merely 

 obsolescent." 



The third maxilliped is shown in fig. 4«, and the abdomen of the 

 male in fig. 4b. 



Colour in spirit : white with brown fingers. 



Measurements of largest specimen (a male) : length 4*5 mm. ; 

 tip to tip of longest side-teeth 7 mm. ; front 7 mm. ; fronto-orbital 

 breadth 6 mm. 



The species is closely allied to C. Icevissimus Dana, but differs 

 from it in several points indicated in the definition. 



Funafuti ; thirty-five males and twenty -four females, all but 

 one male from 15-25 fathoms. 



Eotuma ; eleven males, seven females.
