RANA. 325 



Lines of muciferous crypts very distinct, as in 

 R. agilis. 



The colour of the upper parts varies from reddish- 

 brown to blackish-brown ; belly greyish or whitish ; 

 caudal crests brownish, the upper darker than the 

 lower, with brown dots and large blackish spots, 

 which are also present on the muscular part. 



Total length, 49 mm.; body, 17; width of body, 

 12; tail, 32; depth of tail, 11. 



Habitat. — Rana iberica, hitherto observed only in 

 Portugal and North-western Spain, is principally 

 bound to the mountains, where it is fouud up to 

 4500 feet or even higher. It has been obtained in 

 Galicia and New Castille ; in the Serra de Gerez, the 

 Valle Passos, near Coimbra and Beira, the Serra de 

 Soajo, near Lisbon, and in the Serra de San Mamede ; 

 it is thus on record from all the provinces of Portugal 

 with the exception of Algarve. 



This species has also been recorded, with some 

 doubts as to the correctness of the identification of 

 a single specimen, from the Lac d'Aubert, Hautes 

 Pyrenees, by Belloc (C. R. Assoc. Franc., Pau, 1892, 

 ii, p. 520). This specimen was probably nothing but 

 an aberrant and badly preserved half-grown Rana 

 temjwraria. 



I am indebted to the kindness of Mr. F. A. Moller, 

 of the Botanic Gardens, Coimbra, for the specimens 

 figured on PI. XXIII. The specimen to the right is 

 a male, that to the left a female.
