Announced by the author as a second edition of his * Mono- 
graph of the AnaVidm^ (published in 4to, with plates, 1838), with 
additions bringing his “ knowledge of that family down to the 
present time,^^ and printed in the present form for the use of 
travellers and students ; it, however, gives a very poor idea of the 
knowledge now possessed by most ornithologists of this family, 
and we would fain let its deficieneies pass in silence. The author 
has been most unfortunate in his printer, and we have seldom of 
late years seen a work of scientific pretension brought out with 
so many errors.

* Some years ago we were told of a very similar case which had been 
observed in the Zoological Garden at Amsterdam ; whether the particulars are 
anywhere recorded we know not. It seems very likely that the supposed 
species C. immutahilis, Yarr. (P. Z. S. 1838, p. 19), has thus originated, though 
when once established the breed is often perpetuated, as happens with so many 
other white varieties of birds and beasts.
