Recently published Ornithological Works. 
We do not quite understand why the articles are headed 
by trinomial appellations, whereas the names on the plates 
are binomial, and we do not like the spelling Dromaius 
for Dromceus. This can hardly be called a case of following 
the earliest spelling, but of foreswearing the practice of the 
Latin language itself. Are we to call iEneas Aineas, or 
Cyrus Kuros ?

22. Pycraft on Birds.

Diagrams. London, 1910: Methuen & Co. 8yo, pp. i-xxx, 1-458.] 
Mr. Py craft’s latest work, while it is of a somewhat popular 
nature, is the first of its kind to be written from the point of 
view of evolution. The idea is, of course, far from being new 
to scientific men, but books written for the general public 
have heretofore either treated the subject from a systematic 
standpoint or at least have not taken evolution as the main 
subject of their discourse. A glance at the table of contents 
will shew the wide scope of the present treatise, which, be¬ 
ginning with an essay on the general structure of Birds, 
their gradual development and relationships, proceeds to give 
a most excellent account of them as they are at the present 
day, their distribution, the effect of their surroundings, their 
migration, and their life-history in general. Their inter¬ 
relations with other animals and plants and their social habits
