M. fcae should be removed from the genus Megaiophri/s , and, 

 notwithstanding its vomerine teetli and ' liorns ' , be transferred 

 to Leptobrachmm. If I am justified in so doing, there is of course 

 no reason for maintining the genus Xenophrijs, which ditiej's 

 from Leploh rack turn in no otlier character l)ut tlie presence of 

 vomerine teeth. 



The genus Leptobrachmm may be defined as Pelobatidae wilh 

 procoelous vertebrae, strongly dilated sacral diapopliyses, coccy- 

 geal style articulating with sacral vertebra by a single cotyle, 

 sternum with a bony style, hidden or indistinct tympanum, 

 vertical pupil, nearly free or shortly W('l)l)ed toes, and large, 

 free, cordiform or py rifornì tongue. And tlie five species at 

 present known may ))e distinguished as follows : 



A. Tibio-tarsal articulation reaching the eye, or beyond. 



Vomerine teeth 1, monticola, Gthr. 



Vomerine teeth none 2. gracile, Gthr. 



B. Tibio-tarsal articulation not reaching the eye. 

 Vomerine teeth none ; no palpebral 



appendage .3. hasseltii , Tsrhudi ('). 



Vomerine teeth none ; several pal- 

 pebral appendages 4. carinoisc , Blgr. 



Vomerine teeth ; a single palpebral 



appendage 5. [eoe, Blgr.
