reversed. But I want more data before I can bring forward 
much that is of value on the important subject of migration of 
birds. Cypselus galilceensis (shown subsequently by Dr. Sclater 
to be no other than our Indian friend C. affinis ) in habits 
corresponds very nearly to our own C. subfurcatus. The Bulbul 
of Palestine is a fine songster (p. 81) ; so is our affine locus 
chrysorrhoideSj and I suspect all of this plain-coloured group, 
which are, in most of the species, adorned on the crissum with 
carnation or saffron. The green-tinted Bulbuls, on the other 
hand, are simply noisy chatterers. Drymceca gracilis (p. 82), I 
before pointed out, is not a typical Drymceca , but a Suya. I see 
Mr. Blyth (p. 44) identifies it with his S. (Burnesia) lepida of > 
India. The colour of its eggs alone would appear to separate 
it. The typical Drymceca have bluish eggs, with brown and 
claret-coloured blotches and streaks. 
I am told that some consider my Oreoperdix crudigularis (Ibis, </ 
1864, p. 426) an Arboricola. That this Formosan bird is allied 
to Arboricola I am prepared to allow, but I cannot admit it 
into that genus, at least not into the genus which includes 
A. torqueola of India, the only species of the group that I have 
by me. The specimen of A. torqueola that I have here was 
kindly sent to me by Dr. Squire (of Pheasant fame) ; and 
O. crudigularis certainly differs from that a good deal in the 
form of the head and the bill. Ours has a much more rounded 
or concave wing, with the quills obtusely ended instead of 
pointed, and its tail is shorter, not surpassing the wings. The 
legs of the two species are somewhat similarly formed, but those 
of ours are red. I am sending home skeletons of this bird, and 
I think there will be found a good deal of difference between 
the osteology of the two. The two species differ from each 
other far more than many other types of distinct genera. I 
hate the “ furor genericus 39 so called, but still my conscience at 
present tells me that I am right in separating these two birds. 
On the 23rd of July my northern collector sent me a box of 
skins from Tamsuy. Among these was a cock Euplocamus 
swinhoii, which had its second long central tail-feather white in 
its inner or upper web instead of black ; the rectrices were, as 
usual, sixteen in number. There were also a pair—but a pair
