342 MR. E. G. BOULENGER ON THE 



Bocognano (now in the British Museum), but we must remember 

 that such a correlation is by no means constant in Corsica, for the 

 figure of the type of /S. cot'sica, in Bonaparte's ' Fauna Italica ' 

 shows the number of spots not to be in excess of that of a typical 

 specimen from Italy, figured in the same work. The spots on the 

 Bocognano specimen, although more numerous, are not smaller 

 than is usual in specimens from Hungary, Bosnia, Roumania,, &c., 

 or, for instance, the one from Italy, so beautifully figured by 

 Rusconi. It is also to be borne in mind that Savi in his original 

 description of /S. Corsica ascribes to it fewer spots than to 

 iS. mactdosa.^ 



Where there is much yellow this is usually also strongly 

 intensified (dark straw- or orange-yellow), whilst scanty yellow is, 

 apart from i-are exceptions, pale (pale sulphur or lemon)*. 



[I cannot agree in the least with this statement, as out of over 

 50 specimens from the Harz Mts. which were recently received 

 at the Zoological Gardens, those in which the yellow constituted 

 the ground-colour were, as a rule, of a paler yellow than those in 

 which the black predominated. Again, in some specimens from 

 Dresden, as my father informs me, and in others from the 

 Harz, with the spots few and of small size, the colour was 

 decidedly orange, whilst in specimens from Brittany and Belgium 

 with much yellow, the latter varied from pale lemon to chrome. 

 A large number of specimens received alive from Hungary 

 (N. Becskeret), mostly with small, or very small spots, few in 

 number, had these orange, not yellow.] 



The author then enumerates, with reference to his own 

 material and some indications in the literature, the local 

 differences in connection with the geographical distribution : — 



1. In specimens from the hilly districts (Riva, Tyrol, 70-120 

 m., Schandau on Elbe, Saxony, 130 m.), and in those from the 

 North-German plain (Minden in Prussia, 50 m.) and from the 

 South of France and Spain {fide Bedriaga), the yellow is dis- 

 tributed in great profusion, the spots of the upper surface being 

 often confluent into broad longitudinal bands, or even becomes 

 the predominant colour, and in the S. French and Spanish Sala- 

 manders the dark ground-colour disappears almost entirely. 

 Besides, the under surface of such specimens is strongly spotted 

 or even entirely yellow, 



2. In specimens from Portugal (var. 7nolleri Bedriaga) red spots 

 formed of a special pigment appear in addition to the mostly 

 numerous yellow spots, which here also invade the ground-colour. 



3. The same remarkable appearance obtains likewise in many 

 specimens from the neighbourhood of Vienna (Hiitteldorf, 

 Modling, Puckersdorf, Hadersdorf, Unter-TuUnerbach), in which 



* " Wo viel Gelb vorhanden ist, da ist es gewoliiilich aucli stark gesattigt 

 (Duiikelstroh oder Orangegelb), wahrend sparliches Gelb, von seltenen Ausiialimeii 

 abgeseheii, blass (Lichtscbvvefel odei- Citrongelb) aussieht. Eei einer raassigeu 

 Quaiititat Gelb treten dieFlecken bald in dunkleren, bald in helleren Schattirungen 

 aaf, jedoch in der Kegel niclit bei ein und demselben, sondcrn bei verschiedenen 

 Exemplaren."
