reversed. But I want more data before I can bring forward 

 much that is of value on tlie important subject of migi'atioii of 

 birds. Cypselus galilaensis (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 Ixus 

 chrysorrhoides, 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. DrymoBca gracilis (p. 82), I 

 before pointed out, is not a typical Drymaca, 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 Drymcecce 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 7'ed. 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 " 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 w^as a cock Eujjlocamus 

 swinhoii, which had its second long central tail-feather ivhite 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
