REFftLIA. 247 



Myobatrachus ScHLEG. (Is this its place?) 



Note. A genus imperfectly known from a single specimen, not 

 very well preserved. Two subulate teeth in palate (vomer); no 

 maxillary teeth. No tongue seems to be present. Feet short, im- 

 mersed in trunk. 



Sp. Myobatrachus paradoxus SCHL. Mus. L. B, from New Holland. 



B. Tongue distinct. 



a) Teeth in upper jaw. 

 + Points of toes not expanded. 



Bombinator MERE, (in part), DuG^S. Cavity of tympanum 

 none. No glandular tuberosities behind eyes. Tongue orbicular, 

 affixed on all sides. 



Sp. Bombinator igneus MERR. Rana Bombina L., Bufo bombinus DAUD., 

 R(ESEL Ran. Tab. 22, 23, CUVIER R. Ani., ed. ill., Rept. PI. 39, fig. i; a 

 small species, dirty brown above, below yellow or orange-coloured with 

 irregular blue-black spots. Bombinator fuscus FITZING., Bufo fuscus 

 LAUR., Pelobates fuscus WAGL., DUM. et BIBR., RCES. Ran. Tab. 17 19, 

 Cuv. R. Ani., ed. ill, Rept. PI. 38, fig. i; this species diffuses an odour re- 

 sembling garlick ; the larvae retain the tail a long time, until they are already 

 very large, much like the Rana paradoxa of Surinam; see below, pp. 250, 

 251. The granular uneven surface of the cranial bones also is peculiar in 

 this species. The hind legs present on the inside of the tarsus a flat, sharp- 

 edged process, covered with hard horny skin; here also belongs a species 

 from the south of France and Spain, named by CUVIER Rana cultripes 

 (Cultripes provincialis MUELL., Pelobates cultripes TSCHUDI). The transverse 

 processes of the sacrum are triangular plates, broad at their extremity, as 

 in the two preceding genera. 



Alytes WAGL. (Spec, of Boinbinator MERR.). Membrane of 

 tympanum distinct. Glandular tuberosities above tympanum. 

 Tongue orbicular, affixed on all sides. Toes of posterior feet joined 

 by membrane at their base alone. 



Sp. Alytes obstetricans WAGL., Bufo obstetricans LAUR., BROKGNIART Essai, 

 &c., fig. 9, STURM DeutscJd. Fauna, Amphib. Heft 4. This small species, 

 which is found in France and Southern Germany, Switzerland and Italy, 

 produces a shrill sound, like that of a bell (the true Rana campisona of 

 GESNER, which LINNAEUS confounded with Rana bombina). It is still 

 more celebrated for the assistance which the male affords the female when 

 laying her eggs, which causes them to adhere to his hind legs by small 

 pedicles. The eggs have a yellow colour; they remain attached to the 

 male, until the embryo is sufficiently developed; then he leaves his place of 

 concealment underground and betakes himself to the water; except at this
