VARIETIES OF THE WALL-LIZARD. 149 
Lacerta muralis reticulata Eimer, Arch. f. Naturg. 1881, pp. 325 & 357, pl. xiii. fig. 12. 
Lacerta muralis neopolitana, var. insulanica Bedriaga, Bull. Soc. Nat. Moscou, lvi. 1882, p. 101. 
Lacerta muralis neapolitana, subvars. g et h (part.), Bedriaga, Abh. Senck. Ges. xiv. 1886, 
pp. 288 & 229. 
“Le Lézard des murailles provenant de l’ile de Pianose laisse voir sur un beau fond 
vert des bandes noires transversales et ondulées. Les parties inférieures du corps sont 
bleudtres. Les séries longitudinales de plaques ventrales qui confinent aux flancs 
sont d’un beau bleu marin tacheté de noir. Les formes de ce Lézard offrent des 
caractéres nouveaux. Sa téte est déprimée, le cou est fortement renflé et beaucoup 
plus large que la téte; son trone est tres-épais. Par ses formes, cette sous-variété 
parait étre trés-voisine du Lézard oxycéphale de Fitzinger [read L. bedriage 
Camerano].” Bedriaga, 1879, p. 205 (italics mine). 
I had quite independently arrived at the same conclusion on examining a specimen 
from Pianosa, near Elba, received after my first contribution (Tr. 1905) had been set up 
in type, and to which I thus alluded in a footnote (p. 384) :—‘ I have received from 
Prof. Camerano a male specimen from Pianosa, which may well be regarded as inter- 
mediate between the vars. brueggemanni and bedriage.”’ 
Before having seen the specimens referred to the var. nigriventris (or ventromaculata 
Bedr.) from the Scuola islet, near Pianosa, alluded to by Bedriaga *, I felt much 
inclined to think that they would prove to be only a darker form of the var. insulanica 
of Pianosa, a supposition which has been fully confirmed by the examination I have 
been able to make of one of Dr. de Bedriaga’s specimens, forming part of his private 
collection, and of several in the Florence Museum. ‘This variety is directly connected, 
through the var. brueggemanni, with the typical LZ. muralis, not with the varieties 
grouped together as subspecies neapolitana. It may be regarded as a form evolved on 
parallel lines with the true var. nigriventris, from the province of Rome, of which I 
had the pleasure of seeing fine, specimens running on the old outer walls of Rome 
in December last. I had a few captured for me, and two were exhibited last winter 
in the Reptile House of the Zoological Society. Some had the spots yellow, others 
had them of a bright green, and a few had the sides of a beautiful lapis-blue between 
the meshes of a black network. 
Before describing the var. ¢nsulanica, I will give particulars of sex, size, and scaling 
in the 14 specimens examined, two being the types, in Dr. de Bedriaga’s Collection 
(Pl. XVIII. fig. 1); the third is the male from Pianosa, received from Prof. Camerano 
and mentioned in 1905, the next eight from the same locality, presented to the British 
Museum by Count Peracca (Pl. XVIII. fig. 2); the first specimen from the Scuola 
islet is in Dr. de Bedriaga’s Collection (Pl. XVIII. fig. 3), and the last two are in the 
Florence Museum. 
* L. c.—By an oversight, I previously referred to this lizard as being from a rock near Pianvsa in the 
Adriatic.
