Dr. Sushkin exhibited some specimens of Jer-Falcons, 

 and other interesting birds, and spoke as follows : — 



" I have much pleasure in being able to exhibit to the 

 British Ornithologists' Club this evening some interesting 

 specimens of birds from Russia. 



" Firstly, on behalf of Professor Menzbier, of Moscow, I 

 exhibit examples of two species of Jer-Falcon. One of them, 

 Hierofulco altaicus, was described by Menzbier in 1892 in his 

 f Ornithologie du Turkestan/ An adult bird was obtained by 

 Eversmann many years ago in the Altai mountains, and was 

 determined by him as H. yyrfalco. 



" More recently Professor Menzbier received from Minu- 

 sinsk a quite young bird of this Jer-Falcon, with the quills 

 still incompletely developed, and he at once detected the 

 differences between it and the Grey Jer-Falcon (H. yyrfalco). 

 Since then some more specimens have been received from 

 the Western Altai mountains, and it is this Hierofalco 

 altaicus which was procured in Turkestan by the Second 

 Yarkand Mission and figured by Sharpe as H. yyrfalco in 

 his report on the birds then collected. The range of the 

 species would therefore appear to be the mountain ranges 

 bordering the plateau of Central Asia on the north and 

 west. 



" I exhibit to-night the young bird mentioned above, as well 

 as a beautiful adult female. It is evident that this bird is 

 more nearly allied to the H. saker group of Jer-Faicons than 

 to the northern Jer-Falcons, as more than half of the tarsus 

 is bare, and the markings on the belly in the adult bird are 

 not transverse, but tear-shaped. 



"A second species of Jer-Falcon is described by Professor 

 Menzbier as 



" Hierofalco lorenzi, n. sp. 

 " H. statura magna, tarsis haud plus quam dimidio plumatis: 

 H. milvipedi propinquus, sed subtiis magis conspicue 

 notatus, notseo multo obscuriore, cyanescente adumbrato, 

 coloreque lateritio-rufo in partibus pennarum expositis 

 oppresso : rectricibus in specimine adulto uropygioque 

 grisescenti- vel cyanescenti-cinereo nee lateritio-rufo
