232 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
Diogenes penicillatus, Stimps., from Japan, is certainly closely 
allied to D. merguiensis, but may be distinguished from it by its 
eye-peduncles, which are longer than the peduncles of the external 
antenuex, by its shorter rostrum, which probably is not spiniferous, 
and by the structure of its hand, the outer surface of which 
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 Hburna. I refer this specimen to Diogenes miles, Fabr.,
