 prove to be really new, I would name it after Mr, R. M. Adam, who 

 first sent me numerous specimens in various stages of plumage 

 from Tirhoot. 



597. PiPASTES ARBOREUS. 



In a late number of ' The Ibis ' I mentioned that, in my 

 opinion, Pipastes agilis, maculatus, and arborens were one and 

 the same species. Previously to writing this I had sent home 

 specimens picked out by Dr. Jerdon from my collection as 

 typical maculatus and typical arboreus, the one being of a greener 

 tint everywhere, the other browner or yellower. I have an 

 enormous series of this species from all parts of India, southern 

 and northern, plains and hills ; and I think I can safely say that 

 they one and all unquestionably belong to the same species as 

 the two typical forms which were sent home. In reference to 

 these M. Verreaux furnishes the following remarks: — "The 

 careful comparisons that I have made prove that your birds are 

 both nothing more than Anthus arboreus, a species very common 

 with us here, I had already in my possession a large number 

 of specimens of these birds from India ; and I had already come 

 to the same conclusion as you have done, that all are referable to 

 this species. This is another of those birds which undergo con- 

 siderable local modifications according to climate and country.-" 



602. Agrodroma campestris. 



Our Indian specimens of this bird appeared to me to differ 

 somewhat from specimens received from Europe, especially in 

 the entire absence of spots. M. Verreaux, while confirming the 

 identity of the species, remarks that the absence of the spots is 

 due to advancing age, and that the same is sometimes observable 

 in old European specimens, and is by means uncommon in 

 those from Northern Africa. 



605. Anthus cervinus. 



Having no European specimens to compare with, and feeling 

 by no means satisfied of the distinctness of the supposed A. 

 rosaceus, I sent a good typical specimen of our Indian form to 

 M, Verreaux, pointing out that A. rosaceus was said to differ in
