species are stated to have occurred in the county ; but the 
evidence as to some of them is not very satisfactory. 
Cara, Gaetano. Osservazioni al Catalogo degli Uccelli di Sar- 
degna pubblicato dal Dotf® Tommaso Salvadori. Cagliari : 
1866. 8vo, pp. 152. 
The author seeks to refute the charges of inaceuracy brought 
against him by Dr. Salvadori (Zool. Rec. i. pp. 44, 45), and 
criticises, in some cases very severely, the work of that naturalist.

The species, with few exceptions, are only designated by their 
native names ; and the author, not being a professed naturalist, 
has failed to distinguish the characters of most of the others so 
as to make them recognizable. 
Degland, C. D., Gerbe, Z. Ornithologie europeenne on Cata- 
logue descriptif, analy tique et raisonne des Oiseaux observes 
en Europe. Deuxieme edition, entierement refondue. 
Paris : 1867. 8vo, 2 vols. pp. 610 and 637. 
The first edition of this work was published in 1849, and has 
long been known. The author. Dr. Degland, intended to bring 
out a supplement, in which he should refute the many charges 
brought against him by Bonaparte ; but dying before this labour 
was performed, his papers devolved upon M. Gerbe, who has 
preferred bringing out a new edition of the whole, entirely re- 
cast, so as, indeed, to become almost a new work. M. Gerbe 
has undoubtedly taken a great deal of trouble, and the new 
edition is thereby much more satisfactory than the old one ; but 
still so vast is the amount of literature relating to European 
ornithology that the present work is still very far from being 
up to the mark. Most foreign journals are ignored or quoted 
at second hand ; and even some important independent works are 
passed over; while some of the original statements of Degland 
have been left untouched, without reference to the time which 
has elapsed since they first appeared *. The number of Euro- 
pean species described is 531. It is much to be wished that a 
competent person would write a careful commentary upon this 
work. {Cf. Compt. Rend. Ixiv. p. 169 ; Ibis, 1867, pp. 240-242; 
A. von Homeyer, J. f. O. 1868, pp. 52-57.) 
Drake, C. F. Tyrwhitt. Notes on the Birds of Tangier and 
Eastern Morocco. Ibis, 1867, pp. 421-430. 
After briefly describing the locality, 142 birds are named, 
short notes being added. Otis arabs is the most interesting of 
them. 
* A remarkable instance of this is in vol. ii. p. 615, where an expression, 
^^il y a line qiiinzaine d’ann^es,” which may or may not have been correct 
when Degland in 1849 published it (1st ed. li. p. 529), still remains.
