G. A. ROULENGER 



Fernando Po: Punta Frailes, Musola, 500-800 m. 



FrcMicli Congo: Fernand-Vaz, N'Djolè. 



o. Hymenochirus feae, sp. n. (PI. I, fìg. 1). 



Xevy closely allied to R. boeltgeri, Tornier, and agreeing 

 with it in every respect except that the fingers and toes are fully 

 webbed to the tips. Uniform blackish brown above and beneath. 



The largest male measures 42 millim , from snout to vent , 

 the largest female 4G. 



Six specimens from Fernand-Yaz, French Congo. 



Bixfoiiidae. 



4. Bufo regularis, Reuss. 



Portuguese Guinea: Bolama, Bissau, Farim, Rio Cassine. 

 French Congo: Fernand-Vaz, Lambarene. 



5. Bufo latifrons, Blgr. 

 Fernando Po: Moka, 1300-1500 m. 



This toad, originally described from the Benito River district, 

 and which has since been found in South Cameroon, is quite di- 

 stinct from any of the varieties of B, regularis. Its parotoids 

 may be quite as prominent as in that species; they are long 

 and narrow and parallel throughout in the Fernando Po specimens. 

 The diameter of the tympanum may equal ^/^ that of the eye. 

 The fingers afe longer and more slender than in B. regularis. 

 Up to the present, although large collections have passed through 

 my hands during the last few years, I have not seen a specimen 

 of B. regularis from Cameroon , the Benito River district , or 

 Fernando Po. 



6. Bufo funereus, Bocage. 

 Fernando Fo: Punta Frailes. 

 French Congo: Fernand-Yaz. 



I now regard B. gracilipes, Blgr., as identical with this species. 



7. Bufo tuberosus, Gthr. 



Fernando Po: IMusola, 500-800 m., Bahia de S. Carlos, 400 m. 



8. Bufo preussi, Matschie. 

 Cameroon: Buea. 



This toad, remarkable for its smooth skin, its hidden tympa- 

 num, its very shortly webbed toes, its very indistinct subarticular 

 and metatarsal tubercles, its very prominent, obliquely truncate
