better to treat them as families, a rank which is claimed for the 
anthropoid apes by many naturalists. 
As no good systematic work on the genera and species of bats 
has been yet published, I adopt the five families as generally 
used in this country, with the genera as given in the papers of 
Dr. J. E. Gray and Mr. Tomes. A monograph by Dr. Peters 
has long been promised, and his outline arrangement was 
published in 1865, but this will perhaps be materially altered 
when the work appears. 
Order—CHIROPTERA.

Frugivora 
ae ae ... 9. Pteropidee ... Fruit-eating Bats. 
Istiophora 10. Phyllostomide ... Leaf-nosed Bats. 
Insectivora 11. Rhinolophidee ...Horse-shoe Bats. 
Gymnorhini 12. Vespertilionide ... True Bats. 
13. Noctilionide ... Dog-headed Bats. 
The genera of Chiroptera are in a state of great confusion, the 
names used by different authors being often not at all compar- 
able, so that the few details given of the distribution of the 
bats are not trustworthy. We have therefore made little use 
of this order in the theoretical part of the work. 
The osteology of the Insectivora has been very carefully 
worked out by Professor Mivart in the Jounral of Anatomy 
and Physiology (Vol. i1., p. 380), and I follow his classification 
as given there, and in the Proceedings of the Zoological Socrety 
(1871).

The next order, Carnivora, has been studied in detail by 
Professor Flower ; and I adopt the classification given by him in 
the Proceedings of the Zoological Society, 1869, p. 4.
