556 Recently 'published Ornithological Works. 
some more parts of this work, which may be said to be well 
planned but rather slowly executed. Part 9 *, recently 
received, is devoted to the Pipridse, a well-known Neotropical 
family of Dentirostral Oligomyodan Passeres, generally of 
small size and of very brilliant colouring in the male sex. 
The author, who is well acquainted with his subject and the 
latest literature on it, recognises 20 genera as appertaining 
to the Pipridse, and gives us excellent a keys 33 to the species 
of each genus. The largest is typical Pipra with 29 species 
and sub-species. The rarest species is Sapayoa (enigma , based 
on a single specimen in the Tring Museum. 
Three well-drawn coloured plates illustrate this excellent 
memoir. 
60. Macoun 3 s Canadian Birds . 
[Catalogue of Canadian Birds. By John Macoun and James M. 
Macoun. 1 Vol. 8vo. 761+xviii pp. Ottawa, 1909.] 
This is a reprint, with corrections and additions, of 
Mr. J. Macoun's ‘ Catalogue of Canadian Birds/ which was 
published in three parts in 1900-4 +. In addition to the 
Dominion of Canada, the authors have included in the 
present edition notices of the birds of Newfoundland, Green¬ 
land, and Alaska, as Nature is not limited by political 
divisions. The classification and nomenclature adopted are 
nearly those of the American f Check-list/ The species 
included in the list are 768. The greater part of the new 
material of the present edition has been written by Mr. J. 
M. Macoun. In the case of the first edition of this useful 
work, we are told that the stock was exhausted almost 
immediately after publication. In consequence of the rapid 
augmentation of the population of Canada now going on, 
we cannot doubt that the same will be the case with the 
present edition.
