24 Mr. T. C. Eyton on the Fauna of Shropshire. 



IV,— An attempt to ascertain the Fauna of Shropshire and 



North Wales. By T. C. Eyton, Esq., F.L.S. 



[Continued from vol. ii. p, 56.] 



IV. Reptilia. 



Lacerta agilis, Linn. (Sand Lizard.) Two British specimens of 

 this beautiful species are in my collection, one captured by myself 

 in the garden of the Inn at Capel Cerrig, the other on the borders of 

 the Weald Moors. 



Zootoca vivipara, Wagl. (Viviparous Lizard.) Common. 



Anguis frag His , Linn. (Blind Worm.) Common in many local- 

 ities in North Wales, particularly on the hills in the neighbourhood 

 of Barmouth. 



Natrix torquata, Ray. (Common Snake.) Common. 



Vipera communis, Leach. (Viper.) Found in many localities, 

 though not very common, amongst which may be named Rudge 

 Heath and Knocker Heath in Shropshire, and on the sea-shore in 

 the neighbourhood of Barmouth. 



Ranu temporaria, Linn. (Frog.) Common. 



Rana esculenta, Linn. (Edible Frog.) Found on the Weald 

 Moors in Shropshire. During the war, some French emigrants w T ho 

 were at Wellington were highly delighted in finding the true sort in 

 this locality. 



Bufo vulgaris, Flem. (Toad.) Common. 



Triton palustris, Flem. (Warty Eft.") Common in pits in the 

 neighbourhood of Eyton. Is this species distinct from the following ? 



Triton punctatus, Bonap. (Common Eft.) Common both in Wales 

 and Shropshire. A variety is found on the Holyhead mountain in 

 spring, under stones, which differs in being of a much lighter colour, 

 and in having two dark stripes on each side of the dorsal line ; the 

 belly is deep orange with much fewer spots than usual ; the total 

 length three inches : the numbering of the vertebrae however is the 

 same as in the common species. 



V. Pisces. 

 Perca fluviatilis, Linn. (Perch.) A common fish both in the 

 rivers and pools throughout Shropshire, but I know of no lake in 

 North Wales in which it is indigenous ; the deformed variety found 

 in the Thames I have repeatedly taken in the Shrewsbury canal. 

 This deformity is by no means peculiar to perch ; I have in my col- 

 lection the back bone of a tench and also that of a roach exhibiting it. 

 It is I suspect produced by the ungenial nature of the water produ-
