ANDERSSON, A NEW LIZARD AND A NEW FROG 11 



The male has a large externa! vocal sac below the mouth. 

 The dorsal pouch of the female is small; its opening is placed 

 about at V* of the distan ce between the vent and the nose and 

 its cavity extends to the middle of the back. The pouch 

 carries four eggs as large as pease. Distinct embryoes are not 

 to be seen; the eggs are probably rather new-laid, nevertheless 

 the remaining eggs in the ovary are all small. 



There are two specimens of this beautiful new frog, a 

 male and a female, fomid by Dr. P. Dusen in the forest at 

 Desiro Rivas, Paranå, sept. 1908.

The differences between the measurements of the sexes 

 are, to judge from the table, rather imimportant. The tympa- 

 num of the male is distinctly larger than that of the female, 

 and in these two specimens the limbs are longer in the female 

 but not more than that the difference might be an individual 

 variation. The colour, as weU, is the same in both specimens, 

 but in the male the dark spöts and minute döts on the back 

 are more numerous than in the female.
