TREFACE. 



In order to facilitate reference to this work, a complete alphabetical 

 iudex of the contents of all the three volumes has been appended 

 to the present part. 



This volume concludes the ' Catalogue of Lizards,' a work to 

 which the Author has devoted nearly four years of undivided labour 

 and energy, and the completion of which would have required a much 

 longer time but for his previous acquaintance with the subject. 

 I feel confident that it will give a fresh impulse to the systematic 

 study of Lizards, and serve as the standard work for many years 

 to come. 



The collection is, with regard to arrangement and preservation, 

 in the most efficient state, although many of the specimens have 

 been in the Museum for more than half a century.
