PALJEOBATEACHID^;. 131 



According to Wolterstorff l , the skeleton figured by Meyer in the 

 i Paloeontographica,' vol. vii. pi. xviii. fig. 1, may be regarded as a 

 characteristic specimen. The variety elegans, Wolterstorff 2 , is of 

 small size. 



Hob. Europe (Germany). 



35549. Fragment of lignite showing the impression of a young 

 larva ; from the Lower Miocene of Rott, near Bonn, Sie- 

 bengebirge. This specimen accords with the one figured 

 by Meyer in the ' Palseontographica,' vol. vii. pi. xx. 

 figs. 1, 3, which is referred by Wolterstorff, in the ' Jahrb. 

 nat. Yer. Magdeburg' for 1885, p. 51, to this species. 



Presented by W. J. Neville, Esq., 1859. 



49464. Fragment of lignite with the impressions of two similar 

 larvae ; from Rott. Purchased, 1877. 



30271. Four fragments of lignite showing impressions of similar 

 larvae ; from Rott. Purchased, 1855. 



Palseobatrachus gigas, Meyer 3 . 

 The largest species ; nearly the dimensions of Bana adspersa. 

 The transverse process of the 8th vertebra joining the sacral process. 

 Eab. Europe (Germany). 



R. 61. Fragment of lignite showing the impression of a larva which 

 may belong to this species ; from the Lower Miocene of 

 Rott, near Bonn, Siebengebirge. This specimen corre- 

 sponds very nearly in size with the one figured by 

 "Wolterstorff in the * Jarhb. nat. Yer. Magdeburg' for 

 1886, pi. x. fig. 3, and provisionally referred to this 

 species. 

 Transferred from the Museum of Practical Geology, 1880. 



Palseobatrachus meyeri, Troschel 4 . 

 Somewhat more slender and smaller than P. diluvianus, with a 

 peculiarity in the structure of the coracoid. The structure of the 

 sacrum is not fully known in the type, but in a specimen pro- 

 visionally referred to this species by Wolterstorff it seems that tho 

 transverse process of the 3rd vertebra alone joined the sacral process,
