Not Clorodius Desmarest, 1823 ; de Haan, 1833. 



I am unable to agree witb Bathbun and Ortmann as to the 

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

 Aleock in considering that Milne-Edwards'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 a, and the abdomen of the 

 male in fig. 46. 



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. 



Botuma ; eleven males, seven females.
