388 Records of the Indian Museum. [Vol. XVI, 



In none of the specimens I hav^e seen is the propodus of the 

 last leg dilated as in Borradaile's M . latipes.^ 



Alcock recorded this species from the Andamans and Mergui ; 

 additional specimens are from the following localities : — 



^o Tor, Sinaitic Peninsula, Red Sea. R. H. S. Sewell. One ?. 



s^fi Backwater at Pamban, Rain n ad 



Dist., G. of Manaar. ... S. Kemp. One (^ . 



~\h^ Fisher Bay, Port Owen, Ta\oy 1. ' Investigator." Two J 



(damaged).

The only specimens in the collection are the male and female 

 examined by Alcock. They differ rather conspicuously in the form 

 of the orbital and antero-lateral teeth. In the female the orbital 

 tooth is shorter than in the male and is separated from the first 

 lateral tooth by a comparatively wide gap (fig. 4), In the male 

 the orbital tooth is curved backwards and upwards, slightly over- 

 lapping the margin of the first lateral tooth (fig. 5). The form of 

 the male chela is shown in fig. 3. 



I have compared these specimens with an example of the very 

 closely allied M. grandidieri , A. Milne-Edwards, from the Red Sea. 

 The differences between the two species have been tabulated by 

 Lenz.* 



Alcock by a lapsus calami states that the Indian examples of 

 this species were obtained in the Andaman Is. They are in 

 realit^^ from Kutch. The species is otherwise only known from 

 Mauritius (Milne-Edwards) and Australia (Ortmann) ; the latter 

 locality is almost certainly erroneous. 



Macrophthalmus brevis (Herb.st). 



Macrophthalnuis cariiiimamis, aitct. 

 1915. Macrophthalmus brevis, Tesch, Zool. Meded. Mus. Leideyi. 1, p. 169, 

 pi. vi, fig. 5 {^ubi. lit.). 



Tesch has shown that the name M. brevis must be employed for 

 the species hitherto known as M. carinimanus. It was recorded 

 b}^ Milne-Edwards under the latter name from Pondicherry, but 

 it is only within the last few years that it has again been found 

 in Indian waters. 



''yfy Paway I., Mergui Archipelago. ' Investigator.' Five. 



The species is known from Mauritius (Milne-Edwards), Pondi- 

 cherry (Milne-Edwards), Singapore (Gray), Halmaheira (de Man) 

 and Celebes (de Man).
