158 MR. G. A. BOULENGER ON THE 
VI.—MALTA anp LINOSA (Supplement). 
With insufficient material before me, I referred, in my previous contribution, the 
lizards from Malta and Linosa to Z. serpa, and maintained the var. fi/folensis for the 
larger form from the Filfola Rock, near Malta. I now find that the characters 
for separating the latter entirely break down, but the Maltese and Linosa varieties are 
sufficiently distinguished by their coloration and their average smaller scaling to be 
separated from the var. serpa. I therefore retain the name /i/folensis, but apply it to 
the lizards from the main island and from Linosa, as well as to those for which it was 
originally intended. Much as I regret using so unsuitable a designation, in view of the 
extended range of the variety, | am compelled to do so in preference to the alternative 
of proposing anewname. I can quite conceive these lizards being united with the var. 
quadrilineata from Corsica and Sardinia, from which some specimens are, to my eye, 
undistinguishable. The only characters which can be adduced in favour of their 
separation is that in the var. guadrilineata there are usually fewer than 70 scales 
across the body (56 to 75 being the ascertained range of variation), and the rostral 
usually touches or enters the nostril, and in the var. fi/folensis there are usually more 
scales and the rostral very rarely touches the nostril *. Further, I am not prepared 
to say that I could, in all cases, tell a Maltese lizard from certain specimens of the 
var. serpa from Italy, or of the var. ¢nsulanica from Pianosa, near Elba. I may repeat 
it again, most of these forms are undefinable by the characters to which we have to 
resort, however greatly they seem to differ when only their extremes are compared ; 
and that is why, until they can be properly diagnosed, I refrain from allowing them 
the rank of species. In its very fine lepidosis this variety shows special affinity to the 
Balearic var. lilfordi. 
The Maltese lizard is now represented by a series of 19 specimens, received from 
Mr. Despott (first four specimens in the table of particulars), Mrs. F. H. Pollen (fifth 
specimen, figured, Pl]. XVII. fig. 6), and Capt. H. Lynes.
