XVII. Some Observations on the Habits and Character 

 of the Natter-Jack of Pennant, with a List of 

 Reptiles found in Cambridgeshire.

It is observed by Dr. Fleming, in his British Animals, 

 that " the history of the Natter- Jack, like that of many of our 

 native reptiles, is involved in obscurity." Under the sanction of 

 such a remark from one of our first Naturalists, I am induced 

 to offer a few observations which I have had an opijortunity of 

 making upon the habits of this species, and to record it as a 

 native of Cambridgeshire. 



This animal does not appear to have been often noticed in 

 this country. Its first discoverer, I believe, was the late Sir 

 Joseph Banks, who found it near Revesby Abby in Lincolnshire, 

 and sent an account of it to Pennant, stating that it was known 

 in the above district by the name of Natter-Jack. This account 

 was afterwards published by Pennant in his British Zoology, 

 (Vol. III. p. 19.) who also says that it occurs on Putney Com- 

 mon. — I am not aware that it has been mentioned by any other 

 British writer, otherwise than with reference to Pennant's original 

 description.
