192 FROM THE GANGES TO THE GODAVERI. 



is an absolute record, either in, the published or manuscript 

 lists which have been available for the purpose. It would 

 doubtless not be incorrect to enter the names of all the local- 

 ities under the headings of many of the common species of 

 known wide range throughout the Peninsula; but if this 

 practice were once entered upon it would be difficult to draw 

 the line. 



I make no attempt here to indicate, by signs or otherwise, 

 the comparative rareness or abundance of different species in 

 the respective districts, since the information available is quite 

 insufficient for doing so with any degree of uniformity. 



The original tabular form in which I arranged my materials 

 for this Paper has one advantage over that, which, at the desire 

 of the Editor, has been adopted for publication. It is, that 

 under the heading of each district the species known to exist 

 within such limits respectively can be seen at a glance. This, 

 however, though an undoubted convenience to local observers, 

 has perhaps little other advantage than that the eye can more 

 readily grasp the main features of the distribution in the case 

 of certain species. On the other hand, error is very apt to 

 creep into a long and somewhat complicated table. It is apt 

 to be misquoted, and the printing is cumbrous and expensive. 

 The present arrangement admits more readily of supplemen- 

 tary remarks being made after each species. 



Before commencing the list it will be. necessary, in order to 

 avoid repetition, to enumerate the authorities which have been 

 quoted in the case of each district. 



Appended to the list will be fouud some remarks on species 

 which have been stated to occur within the area, but which 

 I have not included, deeming the evidence of their occur- 

 rence as insufficient. The most remarkable species met with 

 just beyond the limits of the sub-province are also enumerated. 

 Some of these illustrate very markedly the value of the sub- 

 province as a natural area of distribution. 



Birds mentioned by Dr. Jerdon as coming from ,l Central 

 India" and the " Eastern Ghats" are not necessarily included, 

 as these geographical expressions are of too vague or too loose 

 an application for the present purpose.
