. British birds. Birds. KfWW5 A Synoptical List of the Accipitres {Diurnal Birds of Prey). By H. Kirke Swann, Parts I. and II. (Wheldon & Co.) 4s. per Part. This List, which is clearly and well arranged, and contains much information in a compressed form, should prove of much use to ornitho- logists. The arrangement is systematic and much in the form of Sharpe's well-known Hand-LisL with the addition of a precis of the main characters of each genus and each species and subspecies. As in Sharpe's Hand-List, the general distribution of each form is given in a separate column. Part I.
. British birds. Birds. KfWW5 A Synoptical List of the Accipitres {Diurnal Birds of Prey). By H. Kirke Swann, Parts I. and II. (Wheldon & Co.) 4s. per Part.

The arrangement is systematic and much in the form of Sharpe's well-known Hand-LisL with the addition of a precis of the main characters of each genus and each species and subspecies. As in Sharpe's Hand-List, the general distribution of each form is given in a separate column. Part I. treats of the Vultures, Harriers, Gos- hawks and Sparrow-Hawks. In this part there is not much of special interest if we confine ourselves to the British List, but we note that Mr. Swann omits England as a place of accidental occurrence for the Egyptian Vulture, although he includes it under the Griffon. We may also note that he separates Goshawks generically from Sparrow- Hawks and that he treats A. atricapillus (recently added to the British List) as a separate species and not as a subspecies of ±he typical Goshawk. In Part II. we have Buzzards and Eagles. In a footnote under Buteo biiteo zimmermannce, the eastern European rufous form of the Buzzard, we find the interesting statement that of eight rufous British-taken specimens in the British Museum six appear to belong to this race and two to Buteo rufiventer {^desertorum), the south-eastern Europe and western Asian form, which Mr. Swann treats as a distinct species. If, therefore, Mr, Swann's conclusions were accepted, both these birds would have to be added to the long list of casual visitors to the British Isles.
