402 CLASS REPTILIA. 



Some subgenera have been recently separated 

 from that of the toads ; thus, 



The BoMBiNATOR, Mer., 



Do not differ from the others, but because their tym- 

 panum is concealed under the skin. Such is in our 

 country, 



Tlie Yellow-bellied Toad^ {Rana Bombina, Gm. Roes. 

 xxii. Daud. xxvi.) 



The smallest and most aquatic of our toads, greyish 

 or brown above, black blue with orange spots below. 

 The hind feet completely palmate, and almost as 

 elongated as those of the frogs ; accordingly it leaps 

 nearly as well as they do. It continues in marshes 

 and couples in the month of June. Its eggs are in 

 small pellets, and are larger than those of the pre- 

 ceding species.* 



OXYRHYNCUS, Spix, 



Have the muzzle pointed in front.f 

 We should approximate to them, 



Spix, X. 1 ; 5. Bengalensis, id. xxxv. 1 ; B. Musicus, id. xxxiii. 2. ; B. Cine- 

 tus, Pr. Max. trois liv.; the B, Agua of the Prince of Wied. Sept. liv.; 

 does not appear to be the same as that of Spix. 



* Add Biifo Ventricosiis. Daud. xxx. 2. A species represented with an 

 exaggerated swelling. 



f Bufo Froboscideus, Spix, xxi. 4, the neighbouring species represented 

 in the same plate, B. Semi-lineatus, B. Granulosus, B. Acutirostris, and 

 those of pi. xiv. Nasicus and Nasutus, connect, too intimately, this sub- 

 genus with the common toads, to be easily preserved.
