CANCROIDEA. 219 



species is a striking character; also the deep, narrow furrow between 

 the areolets, which are all flat excepting the three near the margin. 

 Upon the posterior part of the carapax the areolets 1 P and 2 P are 

 imperfectly separated. The right anterior leg, which is the smallest 

 of the pair in the specimen examined, has the carpus and hand both 

 spinous, and the moveable finger spinulous near base; while the left 

 or large hand has the moveable finger not spinulous and the spines of 

 the carpus are reduced to short tubercles. The fourth and fifth joints 

 of the eight posterior legs are somewhat spinulous above, and so also 

 the tarsus. 



PlLODIUS PUGIL. 



Carapax paulo nitidus antice areolatus, postice fere planus, areolis 5 L 

 QLdiscretis, 1L 2L 3 L subconicis, IE 2 R paulo discretis; margine 

 antero-laterali k-dentato, dente E fere obsolete, dentibus tribus posticis 

 valde acutis. Pedes antici validi, manu carpoque bene tuberculosis 

 tuberculis plerumque conicis, manus minoris spiniforrnibus, angulo 

 carpi interno duobus spinis tenuibus acutis armato, brachio apioem 

 anticum spinoso. Pedes postici pilosi, articulo tertio supra armato. 



Carapax somewhat shining, anteriorly faint areolate, posteriorly nearly 

 flat, areolets 5 L, 6 L faintly separated, 2 L, 3 L, 4 L distinct, 1 R, 

 2 R separated ; antero-lateral margin four-toothed, the tooth E 

 being obsolete or nearly so, the three posterior prominent and 

 acute. Anterior feet stout, hand and carpus neatly tuberculous, 

 tubercles mostly conical, inner angle of carpus armed with two 

 slender acute spines, arm having a spine at anterior apex. Pos- 

 terior leg pilose, third joint armed with spinules along upper 

 margin.
