Entire surface, excepting lobes of front, fingers and horny tips of dactyls of legs, 

 concealed by a thick, shaggy coat ; on the greater part of the carapace and the dorsal 

 surface of the chelipeds, the coat consists of fine, rather long, dark hairs ; but on hinder 

 and lower parts of the crab and in regular tufts on the carapace it is composed of longer 

 light-coloured tubular hairs. "When the hair is removed, the carapace is seen to be 

 moderately convex, the posterior half flat, regions distinctly marked, but not lobulate ; 

 irregularly placed, conical granules scattered over the surface. Antero-lateral margin 

 divided into 4 ill marked teeth, besides the orbital angle, all of which are granulate. 

 Orbital margin granulate, a larger granule above near outer angle ; no emarginations ; 

 a distinct gap below outer angle ; a thick subacute tooth at inner angle. Front narrow, 

 a little more than £ as wide as carapace, lobes deflexed, separated from each other and 

 from the narrow, prominent blunt outer tooth, by a broad V. Chelipeds equal ; arm with 

 a small, subdistal tooth above ; wrist and palm granulate ; the granules cover the outer 

 surfaces of the palm and the larger ones are arranged somewhat in rows ; the granules as 

 well as the hair are continued a short way on the fingers ; the latter are flat and brown, 

 the colour extending back half the length of the palm ; a longitudinal groove near upper 

 margin of dactylus. Legs short and broad, dactyli long and very slender. 



This species is distinguished by its shaggy coat, quite different from that of any other 

 Actcea and resembling that ofBanareia ; it also differs from typical Actcea in lacking lobules 

 or subdivisions of regions. In many respects it resembles B. armata A. Milne Edwards 

 (Ann. Soc. Entom. France (4), ix. 1869, p. 168, pi. 8), but lacks the deep excavations 

 in the edge of the buccal cavity (which is said to be an unstable character in B. armata), 

 the areolations of the carapace, and the bare space in the palms.
