LA CERT A MURALIS IN WESTERN EUROPE AND NORTH AERICA. 381 



for its pale green coloration with peculiar markings. This he proposed to designate 

 as var. brueggemanni, after his friend the late Dr. F. Briiggemann, and regarded it as 

 unquestionably forming the passage from the typical form to the var. neapolitana. 

 He describes the head as rather strongly depressed, the masseteric disk small or absent, 

 and the caudal scales slightly pointed. The largest specimen measures ISO millim., of 

 which the tail takes up 120. The females are more " simply coloured" and more of 

 a greenish brown than the males, of which he gives the following description from 

 life : — Ground-colour yellowish green or pale green, with fine wavy black cross-streaks 

 forming a network on the sides, which encloses many pale blue spots, the meshes on 

 the shoulder considerably larger and representing the ocellus characteristic of the 

 var. neapolitana. Upper surface of head brown, spotted with green. Limbs grey or 

 green above, with pale green ocelli. Upper surface of tail greenish brown, with dark 

 brown zigzag markings. Belly whitish, spotted with black, one spot to each shield ; 

 the outer series of ventral shields entirely blue ; lower surface of head with white, 

 black-edged ocelli. 



The British Museum now fortunately possesses one of the type specimens (received 

 from Dr. de Bedriaga) from which the above description was taken; and, quite recently 7 , 

 Mr. Bryan Hook presented to the Museum several specimens, captured by him on 

 walls at Lerici, near Spezia, which agree with the types in most respects. Specimens 

 from Genoa, Sestri Ponente, Portofino, Bapallo, and Bologna have also been received 

 from Dr. Gestro, Prof. Camerano, Dr. Wolterstorff, and Dr. Werner. I have besides 

 examined several specimens from Livorno and Bellagio belonging to the Basle 

 Museum; and one from Mount Meta, Terra di Lavoro, belonging to the Museum 

 of Naples University — this being the southernmost point whence this variety has 

 hitherto been reported.
