Bujo mocquardi Angel, 1924, Bull. Mus. Hist. Nat. Paris, p. 270 (Mt. Kenya, 

 Kinangop and vicinity, K. C); 1925, Reptiles et Batraciens in Voyage de 

 Ch. AUuaud et R. Jeannel en Afrique Orientale (1911-12), p. 56, pi. 3,

4 (U.S.N.M. 40975-6, 41676, 43007) Mt. Kenya, K. C. (Mearns and 

 Loring) 1909. 



1 (U.S.N.M. 41793) Wambugu, K. C. (Mearns) 1909. 



All five toads are females and were taken at 5,300 feet at Wambugu 

 and between 8,500 and 10,000 feet on Mount Kenya on October 4, 

 11, and 22, at which time they have the ovaries very distended wdth 

 spawn. The species is a very distinct one though so recently described. 

 While three exhibit markings similar to those in Monsieur Angel's 

 figure, those of another are somewhat reminiscent of the markings 

 of B. regularis, while a fifth is colored uniformly muddy brown. 

 Only the most trifling variations from the original description are 

 presented in this series; thus the snout is slightly longer than the 

 orbital diameter; the interorbital space is narrower than, or equal 

 to, as well as "broader than," the upper eyelid. The stomach of 

 the only specimen examined held many reddish ants and the remains 

 of a few beetles.

A very dried 35-mm. frog with typical markings and characteristics. 

 The species has an extensive range from South Africa to Eritrea. 



" Noble has proposed (1927) the name Polypedatidae for certain genera of frogs here included under 

 Ranidae as the proposed division appears to be an unnatural one. Polypedatidae would include 

 Megalixalus, Hyperotins, Chiromantis, and Leptopelis mentioned in this paper.
