107. Phrynichns pusillus, Pocock, A. M. N. IL (6) xiv, p. 296, 

 1894. 



Closely allied to P. lunatus, but much smaller and much more 

 coarsely granular than the adults of that species, the carapace 

 being beset with large granules and the terga sparsely covered with 

 them, about twenty being scattered over the surface and twenty 

 arranged along the posterior edge, the interstices being very visibly 

 and finely granulated. The integumental folds of the. 2nd abdo- 

 minal sternum obsolete. 



Total length of c? and $ up to 15 mm. 



This species is assumed by Kraepelin to be based upon young 

 examples of P. lunatus. Young specimens of the latter, however, 

 resembling P. pusillus in size, may be at once recognized by the 

 much finer granulation of the integument, the presence and large 

 size of the third tibial spine of the chela, the much shorter chelae, 

 and the presence of the semilunar lobes on the 2nd abdominal 

 sternum. 



Loc. Ceylon: Punduloya (Green), 



Family CHARONTID^E. 



Anterior sternal plate lanceolate, evenly narrow from base to 

 point, without any basal plate-like expansion ; median and posterior 

 sternal plates small, subcircular. Tibia of the 4th leg consisting 

 of four or three segments. Distal spines on upper side of tibia of 

 chela directed inwards and scarcely overlapping the base of the 

 hand. Tarsi consisting of five segments ; the distal with pulvillus 

 beneath the two claws. 



Distribution. Seychelles ; Burma, Andaman Islands, Philippine 

 Islands ; and over the whole of the Indo- and Austro-Malayan area 

 as far as the Solomon Islands.
