and the var. meridionalis, and affords a further argru-

Habitat. — The range of Hyla arborea extends across 

 the Pahearctic region, from Western Europe, North- 

 west Africa, Madeira, and the Canary Islands to Corea, 

 Japan, China, and Hainan. The northernmost points 

 of its habitat are Southern Sweden and Livonia, and it 

 is absent from the British Isles. The typical form is 

 distributed over the greater part of Europe, with the 

 exception of Southern France, and occurs also in 

 Transcaucasia and Asia Minor. The var. intermedia 

 is only known from Italy and Sicily. The var. savignyi 

 is found in Corsica, Elba, Sardinia, Asia Minor, Cyprus, 

 Syria, Lower Egypt, Mesopotamia, Persia, Central Asia, 

 Corea, China, Japan, and Hainan. The var. meridio- 

 nalis inhabits the south of France, Spain and Portugal, 

 Liguria, Emilia, Sicily (?), Tunisia, Algeria, Morocco, 

 Madeira, and the Canary Islands. 



The typical form reaches an altitude of 3300 feet in 

 the Alps, according to Fatio. 



Of the three specimens figured on PI. XIV, two, 

 male and female, belong to the typical form from 

 Belgium ; the third, on the right-hand side, is a female 

 of the var. meridionalis from the Riviera. 



Specimens of the var. savignyi are represented on 

 PI. XV, figs. 1 and 2, from Sardinia (Lataste Collec- 

 tion) ; fig. 3, from Cyprus (Rolle) ; fig. 4, from Wady el 

 Kurm, Syria (Tristram); fig. 5, from Tsu-Shima, Japan 

 (Hoist); fig. 6, from Daibutz, Japan (J. Anderson).
