THE SCINCOID, or SKINC^FORMED LIZARD. 
Lacerta Scincoides., 
This Lizard comes nearer to the Seincus than any I am 
acquainted with, but is ftill a difl:in<ft fpecies. 
In the two fpecimens fent over by Mr. White, one had 
a procefs on the upper part of the tail, near the top, almoft 
like a fupernumerary or forked tail, but which I rather con- 
ceive to be natural; and as this one was a male, I am inclined 
to think that this is peculiar to that fex, which would in 
fome degree have been more clearly made out, if the other^ 
which had not this procefs, had proved a female ; but as 
its being gutted and ftufFed before I faw it, prevented my 
examination, this remains flill to be proved : but what 
makes the conjedlure very probable, is, that it is mentioned 
by Mr. White that fome are without, and fome with this 
procefs. Now if it was a monfter, arifing either from acci- 
dent, or originally fo formed, it would hardly be fo com- 
mon as to be taken notice of. The tail is longer than that 
of the Scincufes, and not fo taper ; the animal is of a dark 
iron-grey colour, which is of different fliades in different 
parts, forming a kind of flripes acrofs the back and tail.
