30 Messrs. L, A. Laiitz and 0. Cyren on 



subspecies is found practically onl}'^ in countries draining 

 towards the Black Sea* — a fact Avliich induced us to 

 choose for the latter the name pontica. Judgiu'^ from 

 several specimens from Mehadia f^ the Hungarian L.prati- 

 cola also belongs to this form. 



Tlie two subspecies may be distinguished by the following 

 characters : — 



1. Lacerta praticula praticola, Eversm. 



Head and limbs comparatively short. Proportion,

Row 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 shield 

 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, lower labials. 

 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-yp-22 gular scales (21 spec). Dorsal scales com- 

 paratively broad and short, rather feebly keeled, and imbri- 

 cate ; in a transverse row across the middle of the body 

 35-59-43 scales (19 spec). In the ^ 26-26-27 (8 spec), 

 in the ? 28-^9-30 (10 spec), transverse rows of ventral 

 plates.

* The specimens examined are from Georgievslro-Osetinskoie (Kuban 

 Valltiy), Novorossiisk, Sotslii, mountains near Adler, Gagry, Gudaiit, 

 Bukliuni, Ananur (valley of E. Aragva) ; the latter locality only belongs 

 to the Caspian Sea basin.
