The plumage and markings of this bird seem generally to accord with 

 those detailed in Dr. Latham's description of his Perdix Cambaien^is, 

 with the exception of their being deeper in colour. The dimensions, 

 however, are very different. Of several specimens contained in the col- 

 lection of the Zoological Society, that from which the above description 

 has been taken is the smallest, and the length of its body rather exceeds 

 10 inches, while that of the Perdix Cambaiensis is represented to be 6 

 inches. With such a difference in the dimensions of these birds, I do 

 not hesitate, even in the absence of all means of actual comparison, to 

 rank them as different species.
