Loc. Kelantan. Four females, three with ova. 



These specimens present all the characters of Dr. Ortmann's 

 species, except one, which is fche presence (in the species) of a 

 spine at the distal and inner under angle of the merus of the Isl 

 pair. This spine is absent in the only one of these specimens id 

 which the legs are present, and the difference is so marked that it 

 seems necessary to regard it as probably varietal. In this reSpecl 

 it resemhles A.hippothoe de Man ; hut may be easily distinguished 

 from that species by the different proportions of the carpal joints 

 of the 2nd pair, and by the presence of a small pleurobranch above 

 the arthrobraneh of the 3rd maxillipede (cf. Coutiere J. c). The 

 outer surface of the hand of the large chelipede is smooth, but 

 the inner surface is slightly granulated, with longish, somewhat 

 scattered hairs.

Loc. ? A male; length 16*5 mm. 



This specimen is without legs, but the same bottle contains also 

 a single large chelipede and two small chelipedes. The spine on 

 the under edge of the merus is situated at the middle of that edge 

 and not at the distal angle.

Loc. Pulau Bidan, Penang. 



A single small example; length 20 mm. 



In the same tube with this specimen are a pair of chelipedes 

 which I have little doubt belong to it. They conform to the 

 Alpheid type, and present no remarkable features ; but, as thev 

 were wanting in Dr. de Man's single specimen, 1 append a brief 

 description and figure. They are unequal in size: the ischium, 

 merus, and carpus generally similar in both (for differences vide 

 figs. 3, 3a), quite smooth; ischium and carpus equal in length,
