44 TROPIDONOTUS SIRTALIS. 



Now Linntcus himself gave the specific name sirtaHs to one; and many years 

 after that, of saurita to the other, well knowing both; of the latter animal there 

 can be no doubt, as his only references are to Catesby and Garden; consequently 

 the specific name sirtalis can only be applied to the serpent now under considera- 

 tion. 



SchoepfT, doubtless, had the Tropidonotus sirtalis in view when describing his 

 Coluber taenia (Die Band Schlange); but his name cannot be retained, as that of 

 Linnaeus has the right of priority.
