APPENDIX 



For the head shields of snakes I have used the names given in 

 Major Wall's book. Nicholson uses a different nomenclature and for 

 the convenience of those who use his book in addition to Wall's or this 

 cue, I append the following list giving Nicholson's names where they 

 differ from Wall's : — 



Wall's. 

 Interuasal. 

 Frae-frontal. 

 Frontal. 

 Parietal. 

 Occipital. 

 Supra-ocular. 

 Supra-labials. 

 Infra-labials. 

 Anterior sublingual. 

 Posterior sublingual. 



Nicholson's. 

 Anterior frontal. 

 Posterior frontal. 

 Vertical. 

 Occipital. 

 None. 



Super-ciliary. 

 Labials. 

 Lower labials.

 Ditto. 



The remainder of the names used for the head shields are the 

 same in each book.
