VIVIPAROUS LIZARD. 39 
nearly similar. The feet are more slender, and the toes 
longer in proportion. The femoral pores, which vary less 
in number than in the other, being generally nine or ten, 
are placed in scales which are very different from the 
corresponding ones in LZ. agilis. Instead of being broad, 
flat, and triangular, and much larger than the orifice of 
the pores, as in that species, they are small, rounded, and 
so little larger than the pores, as to appear merely as the 
sides of atube. This is a very tangible character, though, 
I believe, not before observed. ‘‘ The following,” says 
Mr. Jenyns, “are sexual distinctions :—In the male, the 
tail and legs are longer in proportion to the body; the 
former is nearly (in some specimens quite) two-thirds of 
the entire length: the hind-leg applied to the side of the 
abdomen reaches to, or passes beyond, the carpus of the 
fore-foot ; the ante-anal lamella is shorter, and broader, or 
more transverse; the under side of the base of the tail is 
flattened with a slight longitudinal depression of the 
middle just behind the vent; during the season of sexual 
excitement, the base of the tail is much dilated at the 
sides, appearing swollen.* In the female, the abdomen is 
longer and the tail shorter, the latter being often not more 
than half the entire length: the hind-leg barely reaches to 
the tips of the claws of the fore-foot ; the ante-anal lamella 
is longer in proportion to its breadth, and of a more de- 
cided hexagonal or pentagonal form; the base of the tail 
is rounded, and never dilated at the sides.” + 
The colours and markings of this species vary greatly. 
The general ground colour of the upper parts is a greenish 
* Tt is in this state undoubtedly the Lacerta edura described by Mr. Shep- 
pard in the seventh volume of the Linnean Transactions, as having the tail 
bulging out a little below the base, as if it had been cut off and set on again. 
This was first detected by Mr. Gray, and published in the Proceedings of the 
Zoological Society for 1654. + Jenyns, Brit. Vert. p. 293.
