records them under the name of var. lilfordi. I have not seen these specimens, but 
I have no doubt that if they were examined as to their scaling they would be found to 
agree entirely with the typical form, which grows to a large size on the Glenan Isles, 
whilst the true var. lilfordi, from the Balearic Islands, can be recognised at once by its 
much smaller scales. I have exhibited before one of the meetings of this Society * 
a totally black individual of the typical form from near Florence, apparently similar to 
others from Bordeaux and the Italian Lakes district, reported upon by Lataste f and 
by Kammerer {, thus showing that these black so-called varieties are not, as generally 
believed, only produced by isolation on small rocks. 
Basing likewise his identification on colour and markings, M. M. Mourgue § has 
recorded the vars. nigriventris Bp., and latastii Bedr., from the Riou Isle, off Marseilles. 
But the specimens he has been so kind as to send me, proved, as I expected, to belong 
to the typical form. I append particulars of these two specimens :—

Now, the var. nigriventris, from Rome (see Tr. 1905, p. 3884), has 55 to 71 scales 
across the body, and 27 to 31 lamellar scales under the fourth toe, and the var. latastii 
(var. serpa, from Ponza, p. 397), 66 to 71 of the former, and 30 to 33 of the latter. 
I have before me a large male specimen from St. Lunaire, near St. Malo (Pl. XVI. 
tig. 1), which still more resembles in its coloration the var. nigriventris of Italy. Its 
upper parts are black, with numerous round lemon-yellow spots, and the pinkish-white 
belly is spotted with black. It is further remarkable in having the anterior nasal in 
contact with the anterior loreal, above the posterior nasal. Along with its particulars 
I give those of a female specimen from the same locality, which has a large transverse 
shield in front of the anal, and a round black spot on almost every ventral shield 
(Pl. XVI. fig. 2).

Here, again, the low number of subdigital lamellie (23) shows that this lizard cannot 
be referred to the var. nigriventris, however much it may resemble it in coloration and 
in size. The latter agrees exactly with that of the Glenan Isles specimens (J. ¢. p. 357), 
which were hitherto regarded as among the largest of the typical form. As size is
