which equals once and a half the distance between the 

 nostrils ; tail acutely pointed, twice as long as the body. 



The descriptions I gave of R. iberica and R. Latastii in 

 1879 were taken from a small number of specimens. I have 

 rewritten the following, which I append for comparison with 

 R. grcnca, upon the rich material which is now in the British 

 Museum, viz. fourteen specimens of R. iberica (Coimbra, 

 Serra de Gcrez, Murqa in Tras os ^lontes) and thirty-five of 

 R. Latastii (Novara, Varese, Venice, Corduvado, Monte 

 Lessini, Padua, Calcinaro, Castelfranco, Treviso, Florence, 

 Bertonico, Turin). 



Rana iberica^ Blgr. 



Head as long as broad or a little broader than long, mode- 

 rately depressed. Snout short, obtuse, rounded ; loreal 

 region not very oblique, slightly concave ; nostril equidistant 

 from the eye and the end of the snout, or slightly nearer the 

 latter; the distance between the nostrils a little greater than 

 the interorbital width, which equals the width of the upper 

 eyelid. Tympanum distinct, its diameter one half to three 

 fifths the diameter of the eye ; the distance between the eye 

 and the tynqjanum equals two thirds to three fourths the 

 diameter of the latter. 



Fore limb nearly as long as the body. First finger not 

 extending, or extending but very slightly, beyond second. 

 Subarticular tubercles of fingers moderately developed. 



Hind limb very long, the tibio-tarsal articulation reaching 

 beyond the tip of the snout in the adult, to the tij) of the 

 snout in the young. Tibia but slightly shorter than the fore 

 limb, and nearly as long as the foot. Toes three fourths or 

 even nearly entirely webbed, the web more or less crescentic- 

 ally notched; subarticular tubercles moderately large and 

 prominent. Inner metatarsal tubercle small, soft, oval, 

 measuring about one third the length oi the inner toe ; a 

 small and more or less indistinct tubercle is usually present 

 at the base of the fourth toe. 



The skin may be perfectly smooth, or the back rough with 

 granules and small round warts; hinder side of thighs 

 granular. Dorso-lateral fold narrow but rather prominent, 

 running straight from the tenq)!e to the groin ; the distance 

 between the dorso-lateral folds on the scapular region equals 

 two ninths to one fourth the length from snout to vent. 



Coloration very variable. Upi)cr parts yellowish brown, 

 greyish brown, i)r reddish, with or without dark brown spots ;
