L. GABR. ANDERSSON, BATRACHIANS FROM CAMEROON. 11 



Chiromantis rufescens Gntr. 



Four specimens; one 24 mm. in length, three 54 — 55 mm. 

 See the preceeding species! 



Petropedetes cameronensis Reich. 

 and Petropedetes newtoni Bocage. 



Of Petropedetes neivtoni there are in the collection three 

 specimens, two males and one female, and of P. cameronensis 

 but one example, a female. Beside those I had for compa- 

 rison a specimen, also a female, of the third species P. jon- 

 stoni, lent to me from the Royal Museum. 



Of the table below appears that the male of P. newtoni 

 has longer limbs than the female; moreover, as previously 

 shown by other authors, the tympanum of the male is con- 

 siderably larger and provided with a central dermal horn. 

 The large glands on the thighs at the male are absolutely 

 wanting in the female specimens. 



Phrynobatrachus plicatus Gntr. 



21 specimens, 14 males and 7 females. 

 They agree completely with Boulenger's description and 

 figure of Phrynobatrachus auritus in Proc. Zool. Soc. 1900, p. 



^ Each specimen is 37 mm. in length.
