HERPET0L0GY OF THE GRAND DUCHY OF BADEN. 181 



Black Forest, but only on such as are near the rivers mentioned 

 by Dr. Paulus (I. c). At Heidelberg I never observed it, and I see 

 Bedriaga notes it has become rarer there of late years. Near 

 the Katzenbuckel mountain, further up the Neckar, I could not 

 detect it, nor yet at another point in the south of the country 

 equally interesting to geologists, the Hohentwiel near Constance, 

 where it is stated to occur. 



In the Bavarian Palatinate L. muralis is considered the 

 commonest lizard, being found both in the mountainous parts, 

 and in the towns and vineyards of the Rhine valley. In the 

 northern districts — near the Donnersberg, for instance — it 

 seemed scarcer, while on all the romantic castles of the central 

 and southern Palatinate — at Dahn, Trifels, Madenburg, Lindel- 

 brunn, Drachenfels, Fleckenstein (of the Niebelungenlied), Weg- 

 lenburg — it is extremely abundant. On the ramparts of the old 

 fortress of Landau it may be seen in great numbers, and in the 

 lanes throughout the whole country it is found promiscuously 

 intermingled with L. agilis. In Elsass it is no doubt also 

 universally distributed. I observed it on the fortifications of 

 Weissenburg,* and along the fine road to Klimbach. 



Specimens from Baden seldom exceed 17 centimetres in 

 length. The males are generally speckled black on dark brown 

 ground, and display a slight greenish iridescence in the light. 

 The females incline more to the immature longitudinal striation ; 

 one or two specimens, indeed, exhibit four unbroken parallel 

 lines along the back. The lower surfaces are usually of a pure 

 white, or delicate pink colour, in very rare cases (in the male sex) 

 assuming a more coppery tint. Throat sometimes, as with 

 L. agilis, with black markings. Palatinate specimens are of 

 greater size and colour-variability. Males with black-spotted 

 throats become more numerous, and the under parts are 

 frequently of a bright orange, which in the corresponding female 

 form turns to a brick-dust colour. It may be observed that with 

 German individuals of this variety the blue spots on the outer 

 ventrals are, as a rule, inconspicuously small, and of greenish 

 appearance, which suggests a sort of compensation on the part of 



* A female specimen from this locality was of a uniform black colour 

 (above) when caught, but in alcohol the markings, revealing the usual 

 characteristics of this race, came out more strongly.
