Assistant keeper at the Bosn.-Herc. Governm. Museum in Sarajevo. 
(With 2 text-figures.) 
When G. A. Boulengeb prepared his excellent work on „The 
Tailless Batrachians of Europe" nothing was known of the habits and 
development of Rana Carrier ani Blge. 
Dr. A. Lendl travelling in the interior of Asia Minor in the year 
1906, has collected many specimens of the above named frog and he 
was lucky enough to find the tadpoles of Rana Camerani on the Bos 
Dagli, at an altitude of 1400 m. on the 16 th of August 1906. 
1 describe now the well-preserved tadpoles as follows: 
Width of body contained 1*4 — 1*6 -times in its length, the 
latter 1*3 — 1*8- times in the length of tail. Nostrils decidedly nearer 
to the eyes than to the end of the snout. Eyes ou the upper surface, 
somewhat nearer to the end of suont than to the spiraculum. The distance 
between the eyes one and a half as great as that between the nostrils. 
Spiraculum directed a little upwards and backwards, much nearer to 
the eye than to the anus, visible from above and from below. Anus 
opening on the right side, close to the lower edge of the subcaudal crest. 
Tail thrice or four-times as long as deep, successively narrowing towards 
the end and bluntly pointed ; upper crest moderately convex, a little deeper 
than the lower, not extending upon the back. The depth of the muscular 
portion is contained, at its base, twice or two and one third-times in 
the greatest total depth. The upper crest takes its origin somewhat behind 
the vertical line drawn at the opening of the spiraculum. 
The muciferous crypts are indistinct. 
The mouth of the tadpole is exactly the same as in Rana 
arvalis Nilss.
