Var. TILIGUERTA. 
The following are particulars of specimens from Palermo in Dr. Werner’s Collection, 
and from Monte Cuccio and Tarmina, collected by Prof. O. Neumann :—

In 10 out of 33 Sicilian specimens examined, the anterior temporal is in contact 
with the fourth supraocular. 
The coloration varies greatly. Some specimens have black spots disposed longi- 
tudinally, with a more or less regular vertebral stripe, as in the Sardinian specimen 
figured by me in Tr. 1905, pl. xxix. fig. 5; others are reticulate all over, or the 
black markings form more or less distinct cross-bars (var. tigris of Kimer), as figured 
on the same plate, fig. 6. In the pattern of markings the var. téliguerta may approach 
very closely certain individuals of the var. bedriagw, as shown by the specimens here 
figured (Pl. XVIII. figs. 7 & 8). The markings on the tail may be very indistinct. 
And, finally, some specimens are uniformly greyish-olive or brownish, and evidently 
represent the L. olivacea and L. puccina of Rafinesque. 
Dr. de Bedriaga has sent me, alive, three specimens from Pantellaria Island, between 
Sicily and Tunisia, which are unquestionably referable to the var. tiliguerta:—

In both the males the supratemporal is in contact with the fourth supraocular. 
In view of our extended knowledge of the range of the var. tiliguerta, the occurrence 
of this form in Tunisia no longer appears improbable (ef. Tr. 1905, p. 419). The 
question whether or not it is indigenous on Minorca (J. ¢. p. 370) remains unsolved.
