Pachycheles lifuensis Borradaile. (Plate i. figs. 2, 2a).

We refer our specimens to the above species, somewhat briefly 

 diagnosed by its author. 



Its nearest ally appears to be P. ^arfea^i^s (A.M.Edw.),* but 

 it differs from the figure of that species given in the "Challenger" 

 Reports in (1) the much narrower front, which is slightly produced 

 medianly; (2) the shape of the orbits, whose external angle is 

 produced as a spine; and (3) the structure of the external max- 

 illipeds, which have the antero-external angle of the ischium pro- 

 duced as a long spine, and the merus slenderer, with its internal 

 lobe cristate. 



From P. scM^|>^ws(M.Edw.),t to which it bears a superficial 

 resemblance, it may be separated by the broader proportions of 

 the carapace, by the shape of the external orbital angles, and by 

 the sculpture of the chelipeds, which in P. sculptus have larger 

 granules arranged in more definite rows and not clothed with 

 hairs, while in the specimens under consideration they carry a 

 plentiful pubescence. 



Two specimens (Liddell).
