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 fragilis, Linn. (Blind Worm.) Common in many local-ities in North Wales, particularly on the hills in the neighbourhood of Barmouth. Matrix 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. Rana temporaria, Linn. (Frog.) Common. Rana esculenta, Linn. (Edible Frog.) Found on the Weald Moors in Shropshire. During the war, some French emigi-ants who 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,^oii2i^. (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-
