spaces [apteria], especially (1) the lateral neck-_, (2) the lateral 
trunk-, and (3) the inferior spaces, besides, more or less cominonly> 
(4) the spinal, (5) upper wing-, (6) lower wing-, (7) crural, and 
(8) head-spaces. These tracts and spaces are then treated of 
generally, and subsequently each by itself, after which a chapter 
is devoted to the curious powder- down feathers found only 
in some birds ; and another chapter, on the anal oil-gland, con- 
cludes the first part of the work. 
The second part relates to Special Pterylography and birds 
are taken group by group, the arrangement being based on their 
pterylological characters as follows : — 
AcciPiTRiNiE : (I.) Acc. diurnce. A. Old-world Vultures. B. New-world 
Vultures. C. Falcons. (II.) Acc. nocturnce.

We have not space to indicate the further subdivisions, and it is 
to be regretted that there is no extended paradigm of the classi- 
fication in the work itself; but this want is probably to be ascribed 
to the natural diffidence of the editors, both German and English. 
The volume is most unnecessarily and inconveniently pub- 
lished in folio. To it are added, by way of Appendix, reprints of 
Mr. BartletPs paper On the Affinities of Balaniceps (Proc. 
Zool. Soc. 1861, pp. 131-134) and Mr. Sclater^s On the Struc- 
ture of Leptosoma discolor’^ (Zool. Bee. ii. p. 88), as well as of 
the author’s ^ Observationes de Avium Arteria carotide com- 
muni ^ (Hal^ ; 1829) . (C/. Ibis, 1865, p. 118, 1868, pp. 96-98 ;
