The Broad-Tailed Lizard

LACERTA PLATURA

L. cauda depresso-plana lanceolata, margine subaculeato, corpore griseo-fusco scabro.

Ungues quasi duplicati. Lingua brevis, lata, integra, seu non forficata; apice autem leniter emarginato.

L. with a depressed lanceolate tail, almost spiny on the margin; the body of a dusky grey colour, and rough.

The claws appear as if double; the tongue is short and broad, not forked, but slightly emarginated at the tip.

This Lizard is strikingly distinguished by the uncommon form of its tail, which is of a depressed or flattened shape, with very thin edges, and gradually tapers to a sharp extremity. This depressed form of the tail is extremely rare in Lizards, there being scarcely more than two other species yet known in which a similar structure takes place. One of these is the L. caudiverbera of Linnæus, in which the tail

appears to be not only depressed, but pinnated on the sides. Another species with a depressed tail has been figured by the Count De Cepede, in his History of Oviparous Quadrupeds.

The present species is about four inches and a half in length. The head is large in proportion; and the whole upper surface of the animal is beset with small tubercles, which in some parts, especially towards the back of the head and about the tail, are lengthened into a sharpened point. The lower surface is of a pale colour, or nearly white.
