PREFACE. 



The object of the present Catalogue is to give a list of all the genera 

 and species of the Monkeys, Lemurs, Colugoes, and Frugivorous Bats 

 in the British-Museum Collection,- with references to other species 

 described from other collections. The letters B.M. after a specific 

 name denote the species that are now contained in the Collection ; 

 and the absence of those letters indicates the species which are desi- 

 derata, and therefore desirable to be procured for the Collection. 



The woodcuts arc the same as wcro prepared to illustrate papers 

 published in the ' Proceedings of the Zoological Society,' which are 

 kindly lent by the Council of that Society for the purpose. 



These sheets were printed in 18G7, when the printing was inter- 

 rupted by my ill health, and have been detained in the hope that I 

 should be able to revise the remainder of the manuscript, which I 

 still hope to print in a separate part at a future time.
