Phrynobatrachus acridoides Cope.

 elephant-tracks 2,500 m. above the sea-level. 25 /a 1911. 22 — 17 mm. in length. 



When trying to identify these specimens I found that they came nearest to Phry- 

 nobatrachus acridoides Cope, though they differed from the description of that species 

 in several points. In some the tympanum was hidden, in some others more or less 

 indistinct, but not in a single one it was distinct, as it, according to the descrip- 

 tions, ought to be in the species mentioned. The skin is smooth or minutely prick- 

 led, without »weak tubercles and plicae above*. Besides, all the specimens have a 

 distinct dark temporal spöt, which I have not seen mentioned in the descriptions nor 

 seen in other specimens of this species, examined by me. The differences mentioned 

 appeared to me to be rather important, and I was very doubtful whether my spe- 

 cimens ought to be considered as Phr. acridoides or perhaps as a new species. To get 

 the question solved, I took the liberty of sending some specimens to Dr. G. A. Bott- 

 in knger, and he kindly answered that they, according to his opinion, were to be 

 determined as Phrynobatrachus acridoides Cope. 



The diagnosis of this species is then to be widened in several points : Tympanum 

 distinct, indistinct or quite hidden. Skin with weak tubercles above etc, sometimes
