778 REPORT OF THE HARVARD AFRICAN EXPEDITION 
Bufo togoensis Ahl. 
1 ex. (M.C.Z. 11983) Banga. 
It is interesting to find this species, so recently described from T ogoland, 
occurring in Liberia. ‘‘In the forest by a brook.”’

Rana occipitalis Ginther

Rana mwanzae Loveridge, 1925, Proc. Zool. Soc., London, pp. 772-774, Pl. I. 
1 ex. (M.C.Z. 11937) Ghanga. 
1 ex. (M.C.Z. 11938) Monrovia. 
3 ex. (M.C.Z. 11939-41) Paiata, St. Paul’s River. 
Dr. G. K. Noble, who has examined the type of R. scherert in Berlin, informs 
us that it is a synonym of Rana occipitalis with which species, indeed, the author 
compares it. We now add to the synonymy Rana mwanzae from near Lake 
Victoria. The creation of this species is in part due to the somewhat incomplete 
and faulty original description of R. occipitalis. The types of mwanzae are 
enormous individuals. 
Rana alleni (Barbour and Loveridge) 
Pseudoxenopus alleni Barbour and Loveridge, 1927, Proc. New Engl. Zodl. Club, x, p. 14.
