LACEETA MUEALIS IN WESTEEN EUEOPE AND NOETH AFEICA. 375 



in spirit, as they are now, such specimens cannot be distinguished from ordinary 



Minorca lizards. 



The Ayre Island specimens are described by Giinther (Zootoca lilfordi) as uniform 



deep shiny black above and of a beautiful sapphire-blue beneath. But some specimens 



from the same island sent to me alive by Sr. Ferrer are only of a very dark brown, with 



the dark markings (lines and spots) of the main island form perfectly distinguishable ; 



pale bluish-green or turquoise-blue spots on the sides of the lapis-blue belly, which 



may bear small black spots. Now that they have been in spirit for many years, Lord 



Lilford's specimens also show very distinctly the dorsal markings. Some of the black 



specimens from La Guardia Island, near Majorca, collected by Senor E. Bosca, have 



numerous pale bluish-green spots on the sides of the body and on the limbs. The 



young of these melanotic insular forms are described by Braun as brown above, 



with dark spots and lines, dark brown or black on the sides, with numerous blue spots, 



the tail dark green ; the belly is greenish in the middle, black spotted with blue 



on the sides l .
