ZOOLOGICAL LITERATURE. 
last year (Zool. Rec. iv. pp. 60^ be published. Mr. Gurney 
has worked into his notes many of the observations made by 
Vierthaler and Dr. A. E. Brehm (Naumannia, 1852, 1853, 
1855-57, and Journ. fiir Orn. 1853-58) in North-eastern Africa, 
besides much else that is of interest, especially in the way of 
rectification of nomenclature. In the first portion of this paper 
one new species (belonging to Hirundinidee) is described and 
figured j and in the second the southern form of Ostrich (see 
Struthionidee) i some peculiarities of which have long been known, 
is treated as distinct from the northern. The second plate re- 
presents Glareola nordmanni.

In continuation of the article noticed last year (Zool. Rec. iv. 
pp. 59, 60) . The families comprehended in this series are Co- 
raciidcBy Oriolidee, Ploceidce, Pt'ingillid(Ey EmberizidcBy Alaudidce, 
and Corvidcc] and the more important features will be found 
noticed under those heads.

1868, pp. 119-121, 242-248. 
The first of these consists of remarks on migration and on the 
species of Gi'aculus found at the Cape (see F elecanidce) . The 
second is more important, and contains notes on some 29 species, 
supplementary to the account of them given by the author in his 
^ Birds of South Africa,^ and having regard especially to their 
mode of breeding and eggs. Another new species (see Laridce) 
is added to the fauna of the Cape. 
Marno, E. Ergebnisse einer Reise in Nord-Ost-Afrika. Zoo- 
log. Garten, 1868, pp. 212-216, 239-242. 
These two papers form part of a series giving the results of 
Herr Casanova^s expedition to obtain live animals in North- 
eastern Africa, and contain the ornithological portion. The 
first treats of the Ostrich, the second of the Birds of Prey, 
Ilornbills, and Marabou.

of South Africa.^ Ibis, 1868, pp. 265-271. 
Some 26 species found by Sir Andrew Smith north of lat. 
26° S., and not hitherto recorded as occurring to the south of 
that parallel, though included by Mr. Layard in his work (Zool. 
Rec. iv. pp. 60, 61), are mentioned, as well as about 6 more 
which would seem to have equal right with the former to a 
* In this notice we mentioned only one new species as having been de- 
scribed by Mr. Layard. We overlooked a second, belonging to the TuV'- 
didee and recorded in the present volume.
