Acanthodactylus boschianus, Bonap. Faun. Ital. 
Snout obtuse. Two supraoculars, the first and fourth being 
broken up into small scales or granules ; subocular usually bordering 
the lip ; temporal scales smooth ; front edge of the ear not or but 
feebly denticulated. Dorsal scales smooth, or more or less distinctly 
keeled, small, rhomboidal, feebly imbricate on the back. Ventral 
plates much broader than long (the largest nearly or quite twice 
as broad as long), in straight longitudinal and transverse series ; 
8 or 10 plates across the middle of the body. A median 
series of broad preanals, posterior largest. The hind limb reaches 
usually the collar or the tympanum, sometimes not beyond the axil. 
Digital denticulations very feebly developed, about equally on both 
sides. Upper caudal scales strongly keeled; basal subcaudals smooth 
or feebly keeled. Young longitudinally streaked black and white 
on the body, with round white spots on the limbs. Adult greyish 
or brownish, with more or less distinct traces of light and dark 
longitudinal lines and longitudinal series of black and pale spots; 
sometimes with large blue ocelli on the sides.
