88 A. Alcock — Carcinological Fauna of India. [No. 1, 



Carapace nearly three -fourths as long as broad, flattish, closely 

 pilose, the transverse ridges distinct and disposed as in T. sima, admeta 

 and investigator is. 



Front cut into 4 lobes {not including the supra-orbital angles) of 

 which the middle pair are the narrowest and slightly the most pro- 

 minent and on a slightly lower plane, while the outer pair are the 

 broadest, being also broader than the arched supra-orbital angles from 

 which they are separated by a distinct notch. 



Antero -lateral borders cut into 5 teeth, of which the first is the 

 largest and the fourth is a mere rudiment, while the fifth is sometimes 

 smaller and sometimes larger than the third. 



Posterior border of the usual shape, its length is nearly half the 

 greatest breadth of the carapace. 



Orbits large, with a somewhat dorsal inclination, their major 

 diameter is about a third the width of the inter-orbital space : the 

 inner angle of the lower border not dentiform. 



Basal antenna-joint about equal to the major diameter of the orbit 

 in extreme extent ; its crest is low and either entire or finely gra- 

 nular. 



Chelipeds pilose, covered with transverse squamiform markings. 

 Two enlarged spines on thd anterior border of the arm, none on the 

 posterior border. Inner angle of wrist strongly spiniform, three 

 spinules on outer angle. Hand costateg with 4 or 5 (usually 4) spines, 

 of which the most conspicuous are the 2 along the inner border of the 

 upper surface. Fingers of the smaller cheliped rather longer, of the 

 larger cheliped rather shorter, than the hand. 



First 3 pair of legs with transverse squamiform markings on the 

 upper surface. In the last pair the merus is nearly twice as long as 

 broad and has the usual spiue on the posterior border, and the same 

 border of the propodite is smooth. 



Sixth abdominal tergum of male with arched sides, the tergum 

 being broader than long and much broader at its base than at its far 

 end, though the base is not quite the broadest part. 



In the Indian Museum are 15 specimens, from the Arakan coast, 

 Andamans, and Persian Gulf. The carapace of an egg-laden female is 

 9 millim. long and 12-5 millim. broad. 



61. Thalamita Hanseni, n. sp. 



Carapace two-thirds as long as broad, slightly convex, somewhat 

 pilose, crossed by transverse ridges which have the same disposition as 

 in T. admeta, sexlobata etc. 



Front deeply cut into 4 lobes (not including the inner supra-orbital
