19. Meyer on scarce Varieties o/Tetrao. 



[Ueber einige seltene Exeruplare von Rackel- und Birkwild in Museum 

 Ferdinandeuni zu Innsbruck. Von Dr. A. B. Meyer. Ferdinandeums- 

 Zeitschrift, 1886, p. 225.] 



Dr. A. B. Meyer, who is, as we all know, our chief autho- 

 rity on, the Grouse and their hybrids and variations, now 

 gives us an account of certain specimens belonging to the 

 Museum. Ferdinandeum of Innsbruck, which have been 

 entrusted to him for examination. Five of these curious 

 freaks of nature are here described and commented upon. 

 They are hybrids or varieties of Tetrao urog alius and 

 T. tetrix. 



20. Muirhead on the Birds of Berwickshire. 



[The Birds of Berwickshire, with remarks on their local distribution, 

 migration, and habits, and also on the folk-lore, proverbs, popular rhymes, 

 and sayings connected with them. By George Muirhead, F.R.S.E., 

 F.Z.S., &c. Vol. I. 8vo. Edinburgh : 1889.] 



This is the first instalment of a work which, as the title 

 indicates, is far more than a mere account of birds as ob- 

 served in Berwickshire alone. Its wealth of illustration — ■ 

 nearly every chapter or article having a beautifully etched 

 vignette — makes it quite a drawing-room book ; in fact we 

 remember nothing like it since the publication of Wise's 

 ' New Forest/ some five-and-twenty years ago. The letter- 

 press has evidently been prepared with great care, its style 

 is excellent and scholarly, a vast amount of antiquarian and 

 etymological research is displayed, and altogether the book 

 commends itself to a far wider circle than that of the mere 

 ornithologist. Those who have not subscribed to it are to 

 be pitied, for to them the price is considerably (and justly) 

 raised.

[Notes on Costa Rican Birds, with Descriptions of Seven new Species

 Nat. Mus. 1888, p. 537.]
