ischium slightly concave, the merus-joint also externally concave, clistally truncated, with 
its antero-external angle somewhat produced and its antero -internal angle (where it is 
articulated with the next joint) obliquely truncated and scarcely at all emarginate. The 
legs are rather elongated ; the chelipedes (in the male) are more than twice as long as the 
carapace to base of rostrum ; the merus rather longer than the palm, with a few granules 
on its upper margin near the base and on its postero-inferior margin, and with a spine 
at the distal end of its upper margin ; carpus short, carinated on its inner and outer and 
(obscurely) on its upper surface ; palm smooth, slightly compressed, carinated on its 
superior and more obscurely on its inferior margin, which is produced and rounded at its 
proximal angle ; the fingers are shorter than the palm and are regularly denticulated on 
the inner margins, toward the distal extremities, which are acute ; they have between 
them, at the base, a vacant interspace when closed, and the dactyl has on its inner margin 
near the base, a strong blunt tooth ; the ambulatory legs are slender and elongated, 
closely pubescent and without spines except a small tooth or spine at the distal ends of 
the merus-joints ; the dactyli nearly straight. Colour (in spirit) brownish-yellow.

The unique example (an adult male) was dredged at the Philippines in 375 fathoms, 
in lat. 9° 26' 0" N., long. 123° 45' 0" E. (Station 210). 
This handsome species is distinguished from the type of the genus ( Anamathia 
rissocma ) by the distinct prseocular spine, which exists also in the West Indian deep- 
water species, Anamathia hystrix (Stimpson), which, however, has but four gastric spines 
on the carapace (in Anamathia rissoana there are only three).

The carapace is subpyriform and moderately convex, with well-developed supraocular 
and postocular spines ; the spines of the rostrum are straight, slender, and slightly 
divergent. The post-abdomen (in the male) is shaped nearly as in Inachus, and is six- 
jointed in both sexes (on account of the coalescence of the penultimate with the 
terminal joint). The eyes are short and retractile. The basal antennal joint is slender 
and attains the front, and is armed on its inferior surface with small spinules and with 
a longer spinule at the antero-external angle. The merus of the outer maxillipedes is 
somewhat elongated and rounded at the distal extremity, where it is articulated with 
the next joint, as in Inachus. As in that genus, the chelipedes (in the male) are well
