CEUSTACEA. 37 



same habit of hiding and shuffling under stones as Porcellana, but unlike that genus it 

 inhabits the coral branches of deep sunken reefs and the cavities of madrepores. 



At the island of Koo-kien-san a species of Eriphia was common, hiding under stones 

 below high-water mark, having the carapace, legs, and chelae covered with stiff red hairs, the 

 colour of the shell itself being dark greenish brown, the legs lighter and banded with dark 

 brown, while the under surface of the body was ultramarine blue, and the terminal joint 

 of the abdomen the same colour. 



The Zozymus lives among rocks, hiding in holes, while Pilumnus is sluggish in its 

 movements, hiding in the crevices and cavities of the under surface of stones below high- 

 water mark. 



1. CARPILIUS, Leach. 



1. CAKPILIUS CINCTIMANUS, White. (Tab. VII. Fig. 4.) 



Thorace sine dente laterali, latissimo; lateribus in quatuor lobos divisis; digitis nigris, subalbis 

 ad extreinitatem ; manu in medio lata nigra fascia cum nigro digiti immobilis commixta ; thorace et peclibus 

 laevibus, intense rubris. 



Hab. Insulas Philippinas. 



Carapace without lateral tooth ; very wide ; the side divided into four lobes ; claws of 

 fore-legs black, whitish at the tip ; fifth joint of fore-legs with a broad black band in the 

 middle which runs into the black of the immovable claw. 



Carapace and legs smooth, of a rich red colour. 



Hab. Philippine Islands. 



2. CABPILIUS SIGNATUS, Adams Sf White. (Tab. X. Fig. 1.) 



Thorace valde convexo, supra punctis carinisque latiusculis impresso, aurantiaco, signaturis pallide- 

 citrinis variegato. 



Hab. In littore Mauritiano. 



Carapace very convex, the upper surface distinctly punctulated and beautifully marked, 

 in the dried specimen, with symmetrical figures of a pale yellow on an orange ground, which 

 are well expressed in our figure ; the several regions are separated from each other by shallow 

 grooves, rendering them much more prominent than in other species of the genus ; the ante- 

 rior convex margin is furnished with long crenulations, the crenulation in front being longer 

 than the one behind. 



Front shghtly projecting, deeply notched in the middle line with an obtuse tubercle 

 before, and a smaller one behind the eyes. 



Fore-leys large, with the claws very black, the under claw with four obtuse tubercles, 

 the hind-legs as in C. corattinus, but the fifth pair are unfortunately wanting. 



Hab. Isle of France.
