30 Messrs. L. A. Lantz and O. Cyrén on 
subspecies is found practically only in countries draining 
towards the Black Sea*—a fact which induced us to 
choose for the latter the name pontica. Julginz from 
several specimens from Mehadiaf, the Hungarian L. prati- 
cola also belongs to this form. 
‘The two subspecies may be distinguished by the following 
characters :— 
1. Lacerta praticola praticola, Eversm. 
Head and limbs comparatively short. Proportion, 
length of pileus ; ; 2 ; 
lengtu of head and body * O22-0°23-0°24 7 in the J (8 spec.)

tow of superciliary granules incomplete and generally 
reduced to a few granules. Occipital generally very small, 
narrower than, or as broad as, the interparietal, and pene- 
trating only a little between the parietals. Always a single 
postnasal, in contact with the internasal. Masseteric siield 
moderate, rarely reaching the first supratemporal, and 
separated from the tympanic by 2, seldom by 1 or 3, rows 
of rather small temporals. 5, seldom 6, dower labvals. 
5 pairs of chin-shields, the first 2 forming a median suture, 
On a line between the suture of the chin-shields and the 
collar 16-19-22 gular scales (21 spec.). Dorsal scales com- 
paratively broad and short, rather feebly keeled, and imbri-

35-39-43 scales (19 spec.). In the ¢ 26-26-27 (8 spec.),

plates.

Valley), Novorossiisk, Sotshi, mountains near Adler, Gagry, Gudaut, 
Suklum, Ananur (valley of R. Aragva); the latter locality only belongs 
to the Caspian Sea. basin.
