124 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
in the adult, these hairs are nearly wanting, being probably worn 
off, so that the inner surface of the palm appears glabrous. 
The inner surface of the fingers is always clothed with rather 
long hairs. 
The meropodites of the antepenultimate and penultimate pairs 
of the ambulatory legs are rather enlarged, so that those e. g. 
of the antepenultimate pair are only twice and a half as 
long as broad. The dactylopodites are lanceolate and much 
depressed.

Macrophthalmus tomentosus is a rather rare species, and has 
hitherto been recorded only from the Philippine Islands, the 
Aru Islands, and New Caledonia.

Two male specimens were collected along with the preceding 
species. 
This species is most closely allied to Macrophthalmus japonicus, 
de Haan, and I have already enumerated the distinctive characters 
of both species in my note quoted above. In the form and struc- 
ture of the cephalothorax both species completely resemble one 
another. In these specimens the inferior margin of the palm 
is rounded and granular, whereas in JL. japonicus it is rather 
acute. The upper margin of the mobile finger is smooth, while 
in IL. japonicus it is granular. The inner surfaces of the palms 
and fingers are densely clothed with hairs.
