Chapter II: Introduction

In the first volume will be found an account of the _Lemuroidea_, and the _Anthropoidea_ as far as the group of the Macaques of the family _Cercopithecidæ_. The second volume continues with the latter genus, and contains the rest of the Monkeys, and the Apes, as well as a summary of the geographical distribution of the species of the Order Primates.

I have not attempted to write a complete synonymy of the species of Monkeys. The literature is scattered over many, often obscure, periodicals, and without seeing the actual specimens described by some of the older writers, it would be easy to introduce a great deal of confusion into the synonymy. I have, therefore, only attempted to give the principal references.

I must express my obligation to Dr. Günther, F.R.S., the Keeper of the Zoological Department in the British Museum, for the facilities of study afforded to me in that institution. To Mr. Oldfield Thomas I am likewise greatly indebted for much assistance, and for many a kindly hint.

Dr. Forsyth Major, who is well-known as one of the foremost authorities on the Lemurs, not only gave me valuable information as to the species and literature of the _Lemuroidea_, but was even so good as to furnish me with the descriptions of several new species.

Lastly, to my friend the Editor, I have to return my sincere thanks for the patience with which he has revised my MSS., and for the verification of numbers of references, only to be found in the great libraries of London, and inaccessible to an author dwelling in the provinces.
