308 Carcinological Finina of India. 



Cbelipeds short:, without any spine on the arm : palm short, high, 

 and compressed, with shaip edges, traversed by a fine raised line near 

 and parallel with the lower border : fingers thin and compressed, about 

 as long as the palm, the upper edge of the dactylus— like that of the 

 palm — fringed with hair. 



Legs a little longer than the chelipeds, the meropodites — especially 

 of the first 3 pairs — mtich broadened and compressed, all having a tympa- 

 num. The dac/yli, even of the last pair of legs, are shorter than the 

 propodites. 



No tympana on the sternum. 



In the Indian Museum are fragments of 3 specimens from Mergui : 

 de Man states that the breadth of the cephalothorax of the largest 

 specimen is nearly 10 millim,

Carapace about as long as, or slightly longer than, broad, little 

 sculptured doi'sally, though its antero-lateral parts are stndded M'ith 

 ve.sioulous granules. Front grooved: a groove runs parallel with either 

 lateral border, and a faint groove crosses either ]X)stero-lateral angle. 

 The side-walls anteriorly have the usual " bmin-couvolutioii " sculp- 

 ture. 



Orbits very oblique and very shallow, almost obsolete. 



The merus of the external maxillipeds is nearly twice as big as the 

 ischium and is finely granular ; a single faint groove, most distinct 

 anteriorly, runs parallel with its outer border. 



Chelipeds between three and four times the length of the carapace, 

 all the joints long, slender, and unarmed : fingers longer than the palm, 

 ■without any conspicuous teeth. 



Legs long, but much shorter than the chelipeds: the meropodites 

 sti'ongly dilated, and with a large " tympanum " : the dactylus of the 

 last pair is longer than the propodite, but iiv the other three pairs it is 

 a little shorter than the propodite. 



On either side of each of the last four ' thoracic sterna is a lai'ge 

 tympanum. 



In the Indian Museum are 19 specimens from the Andamans and 

 11 from the Coromandel coast. The carapace is 10 millim. long.
