Clarke/ 5 and Mr. Barrington hastens to disclaim any idea of 
the kind. For ourselves, we had read the Preface before this 
slip was issued, without the slightest suspicion of an amari

106. Bianchi on the Genus Tetraogallus. 
[Uebersicht der Arten der Gattung Tetraogallus Gray. Von V. Bianchi. 
Aus dem Russischen iibersetzt von Michael Harms. J. f. 0. 1899, 
p. 421.] 
Herr Harms has translated from the Russian original 
BianchPs revision of the species of Tetraogallus, published 
in December 1898 in the ‘ Annuaire du Musee Zoologique 5 
of the Imperial Academy of Sciences of St. Petersburg. 
The species of Tetraogallus usually recognized are six : — 
TT. caucasicus , caspius } him,alayensis, altaicus, tibetanus, and 
henrici. To these M. Bianchi proposes to add two new sub¬ 
species of T. himalayensis , namely, T. h. grombczewskii

Altyn-tagh, Western Nan-schan, and Southern Koko-nor 
chains). All the eight forms are carefully diagnosed and 
their ranges are fully described.

Among the meritorious works issued of late years on the 
birds of counties or areas the present volume takes very high

traneous matter, but a plain record of observations. The 
announcement that our M.B.O.U., Mr. Frank Nicholson, 
has read the proofs is in itself a guarantee of the quality 
of the field-notes, for his acquaintance with the districts 
surrounding Cheshire, as well as the county itself, must be 
almost unrivalled. The physical features of the areas into
