sex; as we find in the Common Lizard that the body of 
the female is longer than that of the male. 
The general colour is brownish grey with a silvery 
glance ; and there are generally several parallel longitu- 
dinal rows of little dark spots along the sides, and, more 
constantly, one along the middle of the back. In some 
individuals the upper part is wholly without spots or lines; 
the sides only being marked with an obscure band. The 
belly is of a bluish black colour, with whitish reticulations. 
The young ones are very light yellowish grey above; the 
sides and belly quite black ; and there is a black dot on 
the vertex, and another on the occiput,—which latter 
gives origin to a slender longitudinal black line down the 
back. 
The total length is from ten to twelve, or even fourteen 
inches: the head half an inch, or a little more. The vig- 
nette gives a representation of the under part i the tail, 
and of the upper part of the head. 
The Anguis Erya« of Linneus, the Aberdeen Snake of 
Pennant, communicated to them by Dr. David Skene, and 
said to have been taken in Aberdeenshire, was certainly 
nothing more than the common Slow-worm ; and, from the 
description, can scarcely be considered even as a variety of 
it, so little does it differ, if indeed it can be said to differ at 
all, from its normal appearance.
