YORKSHIRE VERTEBRATE FAUNA. xli 



REPTILES AND AMPHIBIANS. 



The British lists given include nine reptiles and seven 

 amphibians, six of each class being recorded as occurring in 

 Yorkshire. The three British reptiles not hitherto found in 

 the county are the Smooth Snake, a species found only in 

 the New Forest, the Green Lizard, a questionable native of 

 Britain, and the Sand-Lizard, a species not unlikely to inhabit 

 Yorkshire, for which indeed it has been reported, but not 

 sufficiently authoritatively to warrant its being accepted. It is 

 notable that both the Turtles which are however but accidental 

 stragglers from tropical seas have occurred off the Yorkshire 

 coast. 



Of the amphibians all the species occur in Yorkshire except 

 the Edible Frog, only admissible as British on the strength of 

 examples introduced within living memory, and successfully 

 naturalised in the Cambridgeshire and Norfolk fens. The most 

 interesting of the Yorkshire amphibians is the Natterjack Toad, 

 which the present work is the means of adding to the fauna. The 

 distribution of the Newts being imperfectly worked out requires 

 further investigation, when no doubt the range of the Palmated 

 Newt will be found more general than at present appears to be 

 the case. 



Compared with other county-lists, very little difference is 

 observable. Norfolk possesses the Edible Frog, and Northumber- 

 land and Durham the Sand-Lizard, while both are deficient in the 

 two Turtles. 



FISHES. 



This group has been but imperfectly investigated in Yorkshire, 

 very few naturalists having devoted attention to the study of 

 the marine species ; consequently there are but scanty materials 

 for ascertaining the faunistic position, or even the relative abun- 

 dance or scarcity of most of the species. Nevertheless the 

 knowledge already acquired justifies the opinion that Yorkshire 

 possesses a rich and varied pisci-fauna, accounted for by the
