ZOOLOGICAL LITERATURE. 
peared at intervals so irregular that it is impossible for us to say 
precisely how much of the whole belongs to the period to which 
this ^ Record ^ properly refers. However, the volume was com- 
pleted last year, and a very valuable one it is, besides being quite 
unique of its kind. It contains a series of plates, by Mr. Erxle- 
ben, over 110 in number, with figures of skeletons, or parts of 
skeletons, of birds, and so well selected from the author's rich 
and well-authenticated eollection, that nearly all the principal 
forms of bird-structure are represented; but it is a drawback 
that the plates are numbered or lettered in such a manner as 
to render reference to them awkward. The letterpress eonsists 
of short descriptions of the osteology of upwards of 450 species, 
systematically arranged, interspersed with general remarks at 
the end of each order. Mr. Eyton's classification is founded 
almost entirely on osteological characters. He divides birds 
into thirteen orders, as follows : —
