NOTES. 501 
sufficient difference exists to warrant its separation, at any 
rate until it can be compared with the type. 
It was procured in the Oudh Terai in October 1865. 
Mr. Manpewtr has obtained specimens of Stachyris rufi- 
Frons, nobis, (S. F., Vol I., p. 479) in the Bootan Doars. This was 
in April last. His specimen agrees precisely with the type. 
In tHE Ibis for 1871, p. 406, I described a Goat-sucker, new 
to our Indian avi-fauna, under the name of Caprimulgus Unwini. 
‘This was reproduced, “ Stray Featuers,”’ Vol. IIL., p. 407. 
When I described the species, I had only one specimen of 
the Huropean Goat-sucker, an English female, a very large 
and dark bird, as unlike my specimens of Unwini, as they 
could possibly be. Not long since I obtained from the Volga a 
Goat-sucker, labelled C. europaeus, which seemed hardly separa- 
ble from Unwini. 
Mr. Blanford, in his excellent work on the Zoology of Persia, 
not having had an opportunity of examining my type, and hay- 
ing only my old meagre description before him, suggested that 
Unwint mizht he identical with mahrattensis. When recently 
he paid me a visit, I protested that this was out of the ques- 
tion, and gave him all the specimens to examine, telling him at 
the same time that my only doubt was, whether Unwint was 
distinct from europeus. 
After examining the specimens, Mr. Blanford informed me 
that he had no doubt that Unwini belonged to the somewhat 
paler and more silvery race met with in Persia, and he 
added that, though possibly many of the Western European spe- 
cimens were much darker and more rufous, he had seen Euro- 
pean specimens, perfectly similar he believed to my bird. 
The fact is, that C. Unwini bears precisely the same relation to 
C. euroepus that C. Kelaarti does to C. indicus. It is a much 
paler, more silvery, and I should say, typically, or possibly 
ought to say on the average, slightly sinaller race. 
Those who mantain Kelaarti must also maintain Unwini. I 
myself believe in neither as specifically distinct, and should sub- 
stitute for OC. Unwini, C. europeus in our Indian lists. 
I have only three undoubted specimens, all from Murree and 
the Agrore Valley, at the extreme north westerly corner of our 
Indian Empire. 
One of these, though sexed a female by Captain Unwin, must, 
I feel now sure, have been a male, and this sadly misled me. 
I have two other specimens, females, one from Sirsa in the 
Punjab, and one from Ktawab, which either belong to the
