 The Cepedeas are known from but one species each of the families 

 Discoglossidae and Pelobatidae; have been found in five species of 

 Hylidae; are well represented in the Bufonidae; are poorly repre- 

 sented in the Gastrophrynidae-(2 species only) ; are not known from 

 the Leptodactylidae and Dendrohatinae; and are abundantly repre- 

 sented in the Raninae. 



The geographic distribution of the Cepedeas may similarly be 

 summarized (fig. 249). From Europe four species are known (in 

 Discoglossus, Bufo [2], Rana), three of which extend to temperate 

 Asia; from eastern Asia, including Japan and Formosa, thirteen 

 species and subspecies are known (from Bufo [6], Kaloula [1], and 

 Ranidae [7] ^^), of which one extends into Formosa and two extend 

 into the East Indies; from Australasia none are known; from north- 

 ern Africa one is reported in Rana esculenta ridibunda; from west- 

 ern Africa two species are known (from Bufo and from Hyperolius, 

 a Eanid) ; from southeastern Africa we know one species (from 

 Phrynom^antis^^di Gastrophrynid) ; from Madagascar and the Sey- 

 chelles Islands two species are reported (from Megalixalus, a Eanid 

 genus) ; from central South America one species is known (in a 

 Hyla), another is reported from Brazil and from Central America 

 (in a Hyla) ; from tropical Central America we know five species 

 (from Hylidae [3], 5m/<9 and Rana) one of which extends into Brazil ; 

 from southwestern North America, including northern Mexico, which 

 belongs to the same geographical region, we know two species (from 

 a Hylid and from a Rana) ; northwestern North America gives us 

 two species (in two Ranas) ; and from southeastern North America 

 we know two species (in a Pelobatid and a Bufo) ; from northeastern 

 North America no Cepedeas are known. 



" These numbers do not total 12, for one of these species of Cepedea is found in botli 

 Bufo and Rana.
