^ The names in the following lists represent the species so described in the latest 

 edition of the British Museum Catalogues of Snakes and Lizards, the specimens 

 having been kindly identified for me by Mr. G. A. Boulenger himself. Thus a 

 reference to those Catalogues will tell the reader what animal is meant, if he is 

 in doubt. In some cases, however, I have added, in brackets, commonly used 

 synonyms. 



^ I only give the Snakes which I have myself examined. Some of these have 

 been previously examined for the lungs by Prof. Cope (these I have marked #), 

 and a number of other species will be found in his paper (7). 



^ In these elongated forms, with rare exceptions, such as Pygopus, the other 

 dimensions of the lungs vary roughly in proportion to the length. 



In these lists " rud." signifies that the smaller lung is so small, not more 

 than iV tlie length of the larger, and usually much less, that it can be of no 

 appreciable use. 



Sm. rud. (small rudiment) signifies that extra care will be needed to find the 

 rudiment, as by cutting open the trachea as advised by Cope, (7) p. 224, so 

 as to find its internal orifice. 



A line thus signifies that I have not found a rudiment.
