Habits. — We know very little yet about the habits 

 of this species. Bosca says it is found in mountain 

 streams and springs and among the grass on their 

 borders, never far from water. Males were observed 

 by him in breeding attire at the end of March, at which 

 time larvas were also to be found. The few specimens 

 I have been able to observe alive made tremendous 

 leaps, and their voice in summer resembled that of 

 B. agilis. A small male in breeding costume, received 

 24th March, 1897, from Mr. Moller of Coimbra, had 

 a rather deeper note, cock, code, code. 



Tadpole (PI. Ill, fig. 5). — This frog is intermediate 

 between B. temporaria and B. agilis in its larval as well 

 as in its perfect state. Width of mouth much less than 

 the interocular space, which equals nearly twice the 

 distance between the nostrils. Series of labial teeth 

 f , rarely f , the second upper series widely interrupted 

 in the middle, the third very short ; first lower series 

 short, hardly half the length of the second, fourth 

 interrupted in the middle. The beak resembles that 

 of B. agilis, and in one of the four specimens before 

 me the upper mandible is likewise provided with a 

 large black tubercle in the middle of its basal portion. 



Tail obtuse, once and a half to once and three- 

 fourths the length of the body, its depth about one- 

 third its length.
