III each the hody has hecome greatly compresserl, with the cai'apace, thoracic sterna, and 

 abdominal torij^itcs proportionately widened, and tlie chelipedes so formed as to adapt 

 themselves to the closing- of the aperture. They arc : — Diogenes miles (Hcrhst), Aiii- 

 culus stngatns (Herbst), Pagitrns platiithomx^, Stm., from the Loo Choo Is., and Cliba- 

 narius eurystcrnus, Hilgendorf, from Mozamlnque and the Malay Archipelago. In the 

 last-mentioned species the flattening is less apparent. 



Distribution. East Indies {Herhst); Ibo, E. Africa {Hilgendorf) ; Tahiti {Ortmanii).

Madras, not uncommon {J. i?. H.). 



The colour (in spirit) is a reddish orange, and the legs show indistinct and pale 

 longitudinal bands. My largest specimen, a male, is 70 mm. long, the right chelipode 

 45 mm. long. 



Distribution. ? E. Africa {Biancoiii, Krauss); Penang {Brit. IIus.); Singapore 

 {W'cdker); Borneo {Miers); ? Hong Kong and Caspar Strait {Slimpson).

Madras, less common than the former species {J. M. H.). 



De Man proposes to unite this species with the preceding, but in my opinion they arc 

 probably distinct. I have never seen a specimen that I had any difficulty in referring 

 to one or the other form ; they occur in the same locality, and in examining a number of 

 specimens I lind the characters of each constant at all stages of growth. In C infra- 

 spinatus the ground-colour is paler, the banding more distinct, a .strong conical tubercle 

 is present on tiie under surface of the merus of the chelipedes, at the inner proximal 

 margin of the joint, and the size is much less than in the other species. In C. cliba- 

 narius the body and legs, generally, carry much moi-e numerous and longer hairs, the 

 sjiinose tubercles on the upper surface of the chelipedes are more strongly marked, aud 

 there is no trace of the inferior meral tubercle.

* This species presents many of the characters of .1. strimtus (Hcrbst),'|to judge from Stimpsou"s short diagnosis: 

 but, as no mention is made of the strigose lines on the cheli]icdes and legs, it is probably distinct.
