joint is articulated, with it at its antero-internal angle ; the chelipedes (in the male) are 
usually small, with slender palms, but are more developed in the Oriental species 
described below ; the ambulatory legs are slender and elongated. 
Of the half-dozen species described as belonging to this genus, and which are 
enumerated by Professor Smith [tom. cit.), one, Anccmathia rissoana, inhabits the 
Mediterranean and the Eastern North Atlantic region ; three, Anamathia hystrix 
(Stimpson), Anamathia modesta (Stimpson), and Anamathia crassa (A. Milne Edwards), 
the Caribbean Sea or Florida Straits ; and two, Anamathia agassizii, Smith, and 
Anamathm tanneri, Smith, the east coast of the United States. 
The fine species described below is from the far distant Philippine Islands. The 
species of this genus generally inhabit deep water, though not the greatest depths at 
which Brachyura may occur. The Mediterranean species has been recorded from com- 
paratively shallow water (20 fathoms) ; the others are found at various depths of between 
80 and 400 fathoms. 1 
Anamathia pulchr a, n. sp. (PI. IY. fig. 1). 
The body is everywhere clothed with very close-set, short, knobbed hairs, interspersed 
among which are finer, longer setse ; the limbs also are closely pubescent. The carapace 
is much longer than broad, subpyriform rather than, subtriangulate, moderately convex 
and armed with long spines, disposed as follows : five disposed in two transverse series, 
and behind these one, longer, on the gastric region ; one on each hepatic region ; one on 
the cardiac and one on the intestinal region; also four on each branchial region, the 
lateral one being very long ; there exists also a prseocular but no postocular spine, merely 
the founded lobe against which the eye folds back ; the spines of the rostrum are nearly 
straight and divergent from their bases ; both are broken, but the longer (broken) spine 
considerably exceeds half the length of the carapace ; the epistoma is about as broad as 
long ; the pterygostomian region is armed with an oblique row of small tubercles, the 
sternum is without spines or tubercles. The segments of the post-abdomen (in the male) 
are all of them distinct and unarmed ; this part of the body has the lateral margins, 
between the fourth and sixth segments, slightly concave ; the terminal segment is 
slightly longer and narrower than the penultimate segment, very little longer than broad, 
and distally rounded. The eyes are small, with the cornese rounded and terminal, and are 
completely retractile. The basal antennal joint is moderately slender, but much more 
robust than the two following joints (as in Anamathia rissoana), it is concave on its inferior 
surface, and has a small spine at its antero-external angle ; the next joint is somewhat 
longer and very slender. The outer maxillipedes are smooth on their outer surface ; the

tunity of consulting Professor Smith’s memoir.
