feebly denticulate. Dorsal scales oval-hexagonal, feebly but distinctly keeled, larger 

 than tibials ; caudals obtusely keeled, 40 in the fourth whorl.

This seems to be the form, supposed to be from Dalmatia, described by Bedriaga, 

 Arch. f. Naturg. 1878, p. 274 {L. muralis fusca aus Dalmatien). 



The specimens from Bosnia, Herzegovina, and Bulgaria have shorter hind limbs, 

 reaching the axil in the males, the wrist or the elbow of the adpressed fore limb in 

 the females, and the foot is not or but slightly longer than the head, sometimes even 

 slightly shorter. This difference can be appreciated by a comparison of the measure- 

 ments of the Bassovica specimen with those of specimens from Bosnia : —

The suture between the internasals is usually extremely short, and the series of 

 granules between the supraoculars and the supraciliaries is incomplete f . The dorsal 

 scales are roundish, or roundish hexagonal, sometimes very distinctly keeled, some- 

 times nearly smooth, always larger than the tibials; in a female from Livno, the caudal 

 scales are very feebly keeled, and the whorls are alternately longer and shorter in a 

 very marked manner; the caudal scales are always truncate or indistinctly pointed, 



* Reproduced. 



t Except in one specimen from St. Peter, Carniola, and in one from Korito, Herzegovina ; in other speci- 

 mens from the latter locality (in Dr. Werner's Collection), these granules may be reduced to 3 to 5, thus 

 showing the absolute worthlessness of this character for distinguishing species in the L. muralis group.
