A similar paper to that on mammals before noticed (Zool. 
Bee. V. p. 10), consisting of two Tables — the first showing the 
number of species of birds (104, errore 108) that have bred, 
and the number of times (671) they have produced young; the 
second, the number of species exhibited (720) in comparison 
with those that have bred, being on the whole 1 in 6 '6. *

Tlicsc five parts* complete the work of which wc have spoken 
several times before (Zool. Bee. iii. p. 48; iv. p. 51, v. p. 38). 
All the species included in them arc Neotroj)ieal, and will be 
noticed under the families to which they belong. The entire 
number of speeies figured in the Avhole work is 104, referred to 
51 genera ; and in most cases a systematic list of the other 
American species of the same genus is appended to the final 
illustration of each. All the plates are by Mr. Smit. \_Cf. Ibis, 
1870, pp. 262-264.]

These two parts form the beginning of what will apparently 
be a very good general work on the class, the best of its kind 
that we have seen. The introduction gives a concise notice of 
the chief general works on the subject; and then follows a trea- 
tise on the anatomy of birds, wherein the author shows that he 
is sufficiently acquainted with the latest investigations of foreign 
as well as of German writers. This is still incomplete, but is 
of a very promising character. The subjects of the plates too 
(all at present anatomical) -are well selected and clearly drawn, 
considering their small size, \^Cf. Zool. Garten, 1869, p. 160;

• Part IX., containing pp. 129-144 and pis. Ixv.-lxxii., though hearing 
date “ December, 1808,” was not, we believe, published till 1809.
