306 Mr. E. J. Miers on Malaysian Crustacea. 



epibrancliial tooth is very small; and the antero-lateral margins 

 of the carapace are defined by a distinct line. The front is 

 less than one third the greatest width of the carapace ; and its 

 anterior margin is marked with a shallow median sinus. One 

 (probably the larger) chelipede is absent in each specimen ; 

 the remaining one is slender ; the carpus is armed with two 

 strong spines, of which the anterior is the larger, on its 

 inner margin ; hand nearly smooth ; fingers slender, straight, 

 and minutely denticulated. Postabdomen of male somewhat 

 constricted in the middle ; the terminal joint longer than 

 broad. 



This species is apparently allied to T. picta, v. Martens, 

 but differs in the spines of the wrist and probably in the form 

 of the postabdomen of the male. No locality was preserved 

 with the specimens.

Bali (an adult female) ; Java (a young male with P. con- 

 vexa). An adidt male and female are in the collection with- 

 out definite locality. 



This species, as Mr. de Man has pointed out, may always be 

 distinguished by the form of the posterior epibrancliial tooth 

 and the absence of spines on the meropodal joints of the legs. 



Paratelphusa convexa. 



Paratelphusa convexa, De Haan (ined.), De Man, Notes from Leyden 

 Museum, no. xix. p. 63 (1879). 



Java (six specimens, including males, females, and young). 

 In three of these specimens the body and legs are spotted or 

 variegated with dark red. Nias (an adult female) ; Borneo 

 (a young female). 



In the young individuals the angular excavation of the 

 inferior wall of the orbit is less marked than in the adult ; and 

 I think it possible that the examination of a sufficiently large 

 series might show that P. maculata is not specifically dis- 

 tinct. 



Catometopa vel Grapsoidea. 



Macrophthalmus carinimanus, M.-Edw. 



A male and female, of which the exact locality has not 

 been preserved, are in the Museum collection, which agree
