The ornitliological portion (pp. 643-719) is fairly treated as 
to its extent, and the in troductory remarks on the nature and 
properties of the class are judicious; but not so much is to be 
said for the systematic portion, though the author deals with 
that in considerable detail, giving even the characters of fami- 
lies, and at least the names of the more remarkable species 
thereto belonging. The general classification of Birds is in 
eight orders — Natatores, Grallatores, CursoreSf Gallinacei, Co- 
lumbae, Scansor'es, Ambulatores , and Raptatores.

Some of these are interesting, and from the ornithologist’s 
rather than the entomologist’s point of view.

The autlior discusses the question of the avifauna of the North 
Pole, and gives a list of 28 species which, he thinks, will cer- 
tainly be found there, while 12 more may possibly reach that 
much-desired spot. \Cf. Ibis, 1870, p. 130.]

This, the first part of a work which h/is occupied its veteran 
author for many years, is so certain to be in the hands of every 
working ornithologist that we do not feel compelled to expatiate 
upon it at such a length as its importance would otherwise re- 
quire. Its object is to give a complete list of all the genera 
with their subdivisions, and of all the species under the groups 
to which they are supposed to belong, — sucli genera and species 
as are contained in the British Museum Coll,ection being typo- 
graphically distinguished. In this way about 1500 genera and 
nearly 7000 species are included, the name of the author to 
whom each is due and the date of the genius being given, while 
some of the principal synonyms and the localities are added, as 
well as references to figures of the species, but not to descrip- 
tions. Herein lies the chief defect ; for had references to the de- 
scriptions been included, the value of the book as a help to work-
