11 rare. In the five specimens of var. oudrii there are only 7 lamellae. In the next, 
var. ragazzi, 16 out of the 32 specimens have 10 lamellae on hoth limbs, nine have 
9 — 10, four have 9, and three have 8 — 9. A glance at the accompanying table will 
show that the lamella? of this variety start at a higher figure than those of either the first 
or second Phalanx, and that the highest number 10 is much more frequent than in either

of them. In this variety the formula 8 — 9 occurs only in two specimens from Alali, 
13 miles N. of Assab, and in one from Shoa, whereas in the four other geckos from the 
last locality the formula is 9 — 10. The presence of 8 — 9 brings these Alali and Shoa 
geckos very close to the geckos of the typical form in number of their lamellae. 
The labial shields (see table, p. 74) yield results much akin to those of the lamellae, 
in this respect: that the upper labials of the first and also of the second Phalanx are 
generally more numerous than they are in var. oudrii, whereas in var. ragazzi they 
never fall so low as they do in these two groups. In the case of the lower labials, they 
are sometimes quite as few in the second Phalanx as they are in the former variety ; 
but this is not so in var. ragazzi, in which, like its lamellae, they start at a higher 
number than do any of the others. Two of the geckos of the second Phalanx with 1 
and 11 lower labials may be taken as representing P. puiseuxi, Boutan (PI. VII. fig. 8). 
They are also distinguished by a low number of lamellae, viz. 8 ; and in connexion with 
this and the low number of labials the fact is borne in upon us that these Galilean 
geckos are more intimately related to those of Algeria than are any of the others. 
The eye, like every other part of the economy of these lizards, is subject to variation. 
In the first and in the second Phalanx it is larger than in the two varieties.
