the antero-external angle of the merus-joint. The chelipedes are moderately robust, with 
the joints very finely granulated; the merus short, trigonous, with an obscure tooth on 
its upper margin, near the distal extremity; carpus with a spine on its inner margin; 
palm without spines or tubercles, finely granulated, rounded above the fingers, distally 
acute and denticulated on the inner margins. The ambulatory legs are slender and 
somewhat elongated, with the joints slightly compressed, but not dilated, pubescent, and 
clothed on the margins with some longer hairs ; the dactyli are slender, styliform, and 
about as long as the penultimate joints. Colour (in spirit) yellowish-white ; fingers of 
the chelipedes chocolate-brown.

Off Matuku, Fiji Islands, in 315 fathoms (Station 173), in lat. 19° 9' 35" S., long. 
179° 41' 50" E. (a male, perhaps not fully grown). 
The bases of the male verges (external genital appendages) originate very near the 
bases of the fifth ambulatory legs.

The specimens referred to this species resemble de Haan’s description of the male in 
that the pubescence of the chelae covers only the upper part of the palm and the base of 
the dactylus ; the spines of the antero-lateral margins are more strongly defined than in 
his figure of the female ; the small spine of the outer surface of the wrist is obsolete, and 
the ambulatory legs (of the first three pairs especially) less hairy. It may be, therefore, 
that the Challenger specimens belong to a distinct but nearly-allied species. 1 The largest 
specimen has the following dimensions : —

1 Whether or not this species he identical with the very briefly-described Eucrate sexd'entatus, Haswell, must remain 
uncertain. Haswell’s types were from the North-Eastern Coast of Australia (Port Denison, 20 fathoms). The Challenger 
specimens certainly belong to the same species as those from the Arafura Sea, referred to in my Report on the Crustacea 
of H.M.S. “Alert,” as Pseudorhombila vestita, var. sexdentata (Haswell).
