Carcinological Fauna of India. 3l5 



far end of the uppev border of the arm : inner angle of wrist dentiform. 

 Legs unarmed. 



A single female from Mei gui : its carapace is 6 millim. long and 

 9 millim. broad. 



15. Litochira setosa (A. M. Edw.), 



Carcinoplax setosa, A. Milne Edwards, Nouv. Archiv. da Mus. IX. 1873, p. 267, 

 pi. xii. fig. 2 : de Mau, Archiv f. Natnrges. LIII. 1887, i. p. 349, and Jouru. Linn. 

 Soc, Zool., XXII. 1887-88, p. 93. 



The only essential difference between this species and the precedino- 

 is that the carapace here is a little more depiessed and tbat the antero- 

 latei'al borders are cut into 2 blunt teeth besides the blunt orbital ano-le. 

 The size is about the same. 



In the Indian Museum are 16 specimens, from the Andamaus and 

 Mergui. 



16. Litocltini angusHfrons, n. sp. 



Carapace, length a little more thau two-thii'ds the breadth. Frouto- 

 orbital border nearly five-ninths the breadth of the carapace in extent. 

 Antero-lateral boi'ders arched, cut into 4 teeth (including the outer 

 orbital angle) the edges and dorsal surface of which are granular : the 

 first 3 teeth are sharply truncated, the fourth is subacute. 



Chelipeds, in the adult male, nearly twice the length of the carapace 

 aud hardly shorter than the legs ; in the female much less thau twice 

 the length of the carapace and markedly shorter than the legs. There 

 is a lobule near the far end of the upper border of the arm, and the 

 inner angle of the wrist is subacute. 



Two specimens, from Bombay aud Karachi. The carapace of the 

 larger is 13 millim. long and 18 millim. broad. 



This species appears to be closely related to Pilumno^lax cilialus 

 Stimpson. 



17. Litochira Beauniontii, u. sp. 



Carapace, length more thau two-thirds the gx'catest breadth, nearly 

 square. The extent of the fronto-orbital border is hardly less than the 

 breadth of the carapace. The antero-lateral borders are hardly arched 

 and are armed with 3 sharp spinules — including one at the outer orbital 

 angle. 



The chelipeds are much shorter than the legs and, like them, are 

 unarmed, except that the inner angle of the wrist is dentiform. The 

 longest (penultimate) pair of legs are more thau 2w times as long as the 

 carapace.
