200 Mr. W. T. Blanford's'ZoolocjicaV Notes. [No. 3, 



whether any other animals or plants have a similar distribution. The 

 only hypothesis which appears to account for the existence of an 

 isolated colony of eastern forms like this is to suppose that, like a 

 geological outlier they were formerly connected with the present main 

 range, and that they existed throughout the intervening area in which 

 they are now no larger found. 



To the south, the range of the^bara singha and red jungle fowl 

 appears again to coincide with that of the sal tree. I have mentioned 

 above the occurrence of the bara singha in Bustar, where Jerdon 

 found both kinds of jungle fowl together, and where the sal tree is 

 also met with. G alius ferrugineus does appear to reach the Grodavery 

 further east, as I heard one crowing not long since in the gorge through 

 which the river runs about 50 miles above Rajahmundry. 



13. Distribution of the black and painted partridges, Francolinus 

 vulgaris , Stephens, and F. pictus Jerd. and Selby. 



Jerdon, Birds of India, pp. 559, 562, leaves the relative distribution 

 of these two species to the west somewhat undefined. I haye only 

 seen or heard of F. vulgaris in Sind. F. pictus abounds through out 

 eastern Guzerat near Baroda and Surat, and I believe, extends 

 throughout Kattiawar. It also occurs, though less commonly in 

 Cutch, where I have seen it. 



Reptilia. 



The garial (Gavialis gangeticus.) 



This crocodile is generally supposed be confined to the Granges and 

 Brahmaputra with their tributaries. It is found also in one other river 

 running into the Bay of Bengal, the Mahanadi of Cuttack. It does 

 not, however, appear to range further south and is unknown in the 

 Godavery. It is wanting in the Nerbudda and other rivers which fall 

 into the sea on the west coast.* It is also unknown in Burma. 



* I have been recently informed on good authority that it exists in the 

 Indus. Editor.
