African moiintain race which separate it from the South African 

 species have been recently discussed *^ and so need not be repeated 

 here. 



Monsieur Angel's specimen shows us that this frog occurs on 

 Kilimanjaro as well as on Mount Meru and in the Usambara range; 

 all three are situated in northern or northeastern Tanganyika Terri- 

 tory. I have not seen the frog from Kilimanjaro which Angel *^ himself 

 refers to R. merumontana. 



Genus PHRYNOBATRACHUS Giinther 



PHRYNOBATRACHUS NATALENSIS (Smith) 



Stenorhynchus natalensis Smith, 1849, lUustr. Zool. S. Africa, vol. 3, Appendix, p. 



24. (Port Natal.) 

 Phrynobatrachus natalensis Boulenger, 1882, Cat. Batr. Sal. Brit. Mus., p. 112.

 1 (U.S.N.M. 41366) Fort Hall, K. C. (Sm. Afr. Exped.) 1909.

 3 (U.S.N.M. 49321-3) Mt. Sagalla, K. C. (Heller) 1911. 

 14 (U.S.N.M. 66910-23) Abyssinia to K. C. (Mearns) 1912. 



The series consists of 10 males, ranging from 24 to 33 mm. in 

 length, with an average of 29 mm., and 9 females, ranging from 25 to 

 34 mm., with an average of 29.4 mm. The largest series is so poorly 

 preserved that conclusions drawn from them would be doubtfully 

 reliable. 



PHRYNOBATRACHUS ACRIDOIDES (Cope) 



Staurois acridoides Cope, 1867, Journ. Acad. Nat. Sci. Phila., vol. 6, p. 198. 

 (Zanzibar.) 



Phrynobalrachus acridoides Boulenger, 1882, Cat Batr. Sal. Brit. Mus., p. 113. — 

 Stejneger, 1893, Proc. U. S. Nat. Mus., vol. 16, p. 738. — Barbour and 

 LovERiDGE, 1928, Mem. Mus. Comp. Zool., vol. 50, p. 203. 



2 (U.S.N.M. 20101-2) Tana River, K. U. (Chanler) 1892. 



1 (U.S.N.M. 39481) Gondokoro, Uganda. (Sm. Afr. Exped.) 1910. 



2 (U.S.N.M. 42186-7) no locality. (Sm. Afr. Exped.) 1909-10. 

 1 (U.S.N.M. 63533) Victoria Falls, Zambezi. (Raven) 1919. 



The series is comprised of three adults, ranging from 24 to 26 mm., 

 and three young, all 17 mm. It is surprising that more specimens 

 of this common species were not obtained by the expedition. The 

 explanation is probably to be found in the fact that little collecting 

 was done at the coast, where it is most numerous, the above localities 

 would seem to indicate that it penetrates inland along the river 

 valleys.
