232 DR. J. G. DE MAK ON THE PODOPHTHALMOUS 



Diogenes 'penicillatus, Stimps., from Japan, is certainly closely 

 allied to D. mergiiiensis, but may be distinguislied from it by its 

 eye-peduncles, which are longer than the peduncles of the external 

 antennae, by its shorter rostrum, which, probably is not spinif erous, 

 and by the structure of its hand, the outer surface of whicb 

 presents a transverse denticulated crest. 



D. rectimanus, Miers, from North Australia, is also a distinct 

 species.

A single specimen, not provided with eggs, was collected at 

 Sullivan Island, inhabiting, like the preceding species, the shell 

 of an Ehurna. I refer this specimen to Diogenes miles, Eabr.,
