392 MR. G. A. BOULENGEE ON THE VARIETIES OF 



spots, while in adult males they are spotted with black and white, the spots often 

 forming ocelli ; a large black spot or an ocellus with blue or green centre often present 

 above the axil ; black spots on the upper surface of the head present or absent ; white 

 black-edged spots on the hinder side of the limbs. Large male specimens have the 

 upper surface of the head bright green. Lower parts white, greenish, yellowish, or 

 reddish, without spots or with a series of black spots on the outer row of ventral 

 plates, which may also bear blue or green spots, usually of small size. The young 

 are always very distinctly streaked, and the two green dorsal stripes are narrower in 

 proportion to the brown ones (text-fig. 6 c, p. 399). 



Further specimens answering to the above description are in the British Museum 

 from Bologna, L. Trasimene (Perugia), Florence, Ancona, Castelfranco near Ostia, 

 Elba, and Corsica. De Betta himself had recorded his var. campestris from Corsica 

 and Borne. More aberrant specimens are the following : — 



Green colour absent 1 , or reduced to a narrow streak on each side of the vertebral 

 stripe (males and females from Turin and Trieste). 



Olive above with three reddish-brown stripes, but no spots (female from Turin). 



Pale brownish grey, with a pale green stripe on each side of the vertebral line ; a 

 trace of a whitish dorso-lateral line ; no spots (female from the sandy shore at Ostia, 

 near Castelfranco, Borne). 



Five black stripes along the back, with narrow light streaks between them (var. 

 multifasciata Positano Spada, from Ponte Salario, near Borne). 



Green above, with a dorso-lateral series of large black spots ; another lateral series 

 of large black spots from axil to groin, and a third on the outer row of ventral plates, 

 which are blue ; no vertebral stripe or series of spots (var. livomensis Bedr., from 

 Colambrone, near Leghorn).

1 One cannot, however, too much insist on the chameleon-like changes that take place in these and other 

 lizards. We know how the male L. agilis may entirely lose its green colour towards the end of summer, 

 and I have observed a brown lizard of the var. campestris, which in life showed no trace of green, turn to 

 pale green on the anterior part of the back after a few hours' immersion in spirit.
