[Plates XVI.-XXIII. and Text-figures 1-4.] 



In pursuance of the plan followed in the paper published in these Transactions in 

 1905 *, I will now deal with the Lizards of South-Eastern Europe and the adjacent 

 parts of Asia, thus bringing to a completion the account of the various forms of 

 Lacerta muralis so far as the material at my disposal will permit. But as I have 

 continued to amass material from the parts of Europe dealt with in the first contri. 

 bution, I will first add supplements embodying the results of an examination of such 

 material as seems likely to advance our knowledge. 



The hope which I expressed that Dr. Werner, Dr. Lehrs, and Prof. L. von Mehely 

 would bring out the results of their investigation of the Eastern forms of this difficult 

 group of Lizards has only been partly fulfilled by the last author, and I do not think it 

 desirable to wait any longer. Dr. Werner has for the present abandoned his intention, 

 and most generously handed over to me, for description, his valuable collection, on which 

 I have largely drawn, and he has further allowed me to keep duplicates for the British 

 Museum. I wish to express publicly to him my hearty thanks. Much further help 

 in various directions has been received from Dr. de Bedriaga and Count Peracca. A 

 visit to Florence last winter, in company with Count Peracca, has enabled me to survey 

 rapidly the beautiful collection, from all parts of Italy, brought together by the late 

 Prof. Giglioli, to whose successor, Prof. Giglio-Tos, I beg to convey my thanks for 

 facilities granted on that occasion. 



My thanks are also due to Prof. Ehlers, of Gottingen, for the loan of the types of 

 L. hieroglypliica, and to Dr. Gaillard, of Lyons, for the loan of Lizards from Asia Minor 

 and the Caucasus. 



The discussions which have arisen between Prof. Mehely and myself concerning 

 the characteristics and relationships of these Lizards have appeared in the following 

 publications : —
