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



In none of the specimens I have seen is the propodus of the 

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



Alcock recorded this species from the Andamans and Mergui ; 

 additional specimens are from the following localities : — 



^^0 Tor, Sinaitic Peninsula, Red Sea. R. B. S. Sewell. One?. 



-\%- Backwater at Pamban, Ramnad 



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

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 ver}' 

 closely allied M. grandidteri , 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 

 reality from Kutch. The species is otherw^ise only known from 

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

 localit}' is almost certainl)^ erroneous. 



Macrophthalmus brevis (Herbst).

 pi. vi, fig. 5 (/(/;/. lit.). 



Tesch has shown that the name M. brevis must be emploj'ed for 

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

 by Milne-Edwards under the latter name from Pondicherry, but 

 it is only within the last few 3^ears that it has again been found 

 in Indian waters.

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

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

 and (Celebes (de Man).
