" Le Lezard ties murailles provenant de I'ile de Pianose laisse voir sur un beau fond 

 vert des bandes noires transversales et ondulees. Les parties inferieures du corps sent 

 bleuatres. Les series longitudinales de plaques ventrales qui confinent aux flancs 

 sont d'un beau bleu marin tachete de noir. Les formes de ce Lezard ofFrent des 

 caracteres nouveaux. Sa tete est deprimee, le cou est fortement renfle et beaucoup 

 plus large que la tete; son tronc est tres-epais. Par ses formes, cette sous-variete 

 paralt etre tres-voisine du Lezard occycephale de Fitzinger [read L. bedriagoe 

 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 ray 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 specinaen from Pianosa, which may well he regarded as inter- 

 mediate between the vars. brueggemanni and bedriagse." 



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 L. mitralis, 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 wei"e 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. insulanica, I will give particulars of sex, size, and scaling 

 in the 14 specimens examined, two being the types, in Dr. de Bedriaga's Collection 

 (PI. XVIII. fig. Ij; 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 (PI. 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 Pianosa in the 

 Adriatic.
