CRUSTACEA OF THE MERGUI ARCHIPELAGO. 33 
In two specimens only the last antero-lateral tooth on each 
side is spiniform ; and this probably has also been the case in the 
third example, but unfortunately in it these teeth seem to be 
broken off. In the specimens from New Caledonia, described by 
M. Alph. Milne-Edwards, the last two antero-lateral teeth were 
spiniform. Not only is the anterior margin of the arms of the 
chelipedes armed with more or less acute tubercles, but some 
are also present on the upper margin. The ambulatory legs are 
densely covered, along their upper margins, with long yellowish 
hairs and, as in the Red-Sea specimen described by me some 
time ago, the upper margin of the meropodites is spinulose and 
not granulose, as stated by Alph. Milne-Edwards. 
Chlorodius sculptus, a very distinct species, has previously been 
found in the Red Sea (de Man), on the shores of the Seychelles, 
the Samoa Islands, and New Caledonia.

Twenty-five rather young specimens of this widely distributed 
species are in the Collection ; all belong to the typical ZL. exaratus, 
M.-Edw. Thirteen were collected at Elphinstone Island Bay 
73,6Q), six at Owen Island (8¢,3 2), and six at King Island 
Bay. One of the Elphinstone-Island female specimens is infested 
with a Sacculina.

Two specimens (¢ @) were collected at Owen Island. The 
cephalothorax of the larger specimen, the male, is 163 millim. 
broad ; whereas the female individual, which is already carrying 
egos, is scarcely 10 millim. broad. According to Milne-Edwards, 
this species, however, attains a breadth of 20 millim.
