CRUSTACEA OF THE MERGUI ARCHIPELAGO. 201 
smooth, though sparsely punctate, and the outer (posterior or 
upper) margin is rounded. The fingers have a punctate surface 
and the inner edges are sharp, a little hairy and minutely 
denticulated. 
The ambulatory legs are ees punctate, but otherwise 
quite smooth and glabrous. 
The cephalothorax of the larger specimen is 103 millim. broad 
and 114 millim. long (from the posterior margin of the carapace 
to the anterior margiu of the buccal cavity).

A male specimen found at Sullivan Island agrees with my 
published description of this species quoted above. 
In this individual, however, the branchial, cardiac, and in- 
testinal regions are not uniformly covered with granules, as in 
the Atjeh specimens, described by me (J. ¢.), but a small spot on 
the middle of the cardiac region and another on either side of 
the branchio-cardiac sutures are devoid of granules. The granu- 
lation of the upper surface of the carapace would therefore 
appear to be somewhat variable. 
Philyra scabriuscula has been recorded from Zanzibar (Hil- 
gendorf), Madras (Novara-Reise), Atjeh and Amboina (de 
Man); it may probably therefore be found to occur elsewhere 
in the Indian Ocean and Malayan Archipelago.

There are five specimens (one adult male, three young males, 
and one sterile young female) of this species in the collection. 
The cephalothorax of the adult male is 16 millim. long (the 
epistome included). In this specimen the upper surface of the 
cephalothorax is sparsely punctate and under a lens is seen to 
be minutely granular on the sides of the branchial regions.
