A female specimen is figured on Pl. XXIX. fig. 9. 
Var. QUADRILINEATA. 
Camerano long ago (Atti Acc. Torin. xiii. 1877, p. 87) recorded the occurrence 
of this form, described by him under the name of JL. tiliguerta, in the vicinity of 
Tunis, where two specimens are reported to have been collected by the late Marquis 
O. Antinori in 1865. These specimens, preserved in the Turin Museum, have been 
kindly entrusted to me for study by Prof. Camerano, and I find one of them to agree 
in every respect with specimens of the var. guadrilineata from Sardinia and Corsica, 
while the other is referable to the Sardinian var. tiliguerta, as pointed out to me by 
ount Peracca. ‘The association of these two specimens points to Sardinia as their 
country of origin, and as, since 1865, no one has ever found either of the Sardinian 
varieties in any part of Tunisia, I cannot help regarding it as highly probable that 
some mistake has taken place in the labelling of the specimens in the Antinori 
Collection. 
It may perhaps be useful to give particulars of the two specimens preserved in the 
Turin Museum :—

The Lataste Collection contains three specimens, belonging to the var. guadrilineata, 
received from M. Ed. Taton as from Cyrenaica. ‘These lizards agree entirely with 
Corsican specimens, and the fact that a Lacerta vivipara bearing the same indication 
of locality was received along with them makes me regard the information as doubtful, 
to say the least. 
I have thus been unable to convince myself of the occurrence of either the var. 
quadrilineata or the var. tiliguerta in North Africa, and I consider the report of their 
presence there as based on erroneous indications of localities.
