Nairobi frogs, being juvenile, lack the brown dorsal patch which is 

 present in the Ulukenya, Guaso Nyiro, Sagayo, and Faradje speci- 

 mens. Having no topotypic Angolan L. anchietae its specific distinc- 

 tion from L. hocagii must be left an open question for the present. 



Through the courtesy of Monsieur Angel I have been able to 

 examine the 40 mm. frog (P. M. 04-360) which ho recently recorded 

 under the name of H. viridis, a species which Boulenger referred to 

 the synonymy of H. hocagii in 1906. Structurally, this frog agrees 

 perfectly with the 42 mm. example from Sagaj^o, a little to the south 

 of Kisumu; the throats of both are granular and the amount of rudi- 

 mentary webbing between the toes is the same.

1 (U.S.N. M. 57726) Ukami, T. T. (Hurter) N. D. 

 This 43 mm., practically topotypic, specimen has been compared 

 with the type with which it agrees, even to the irregular spotting of 

 the back, the orange fading to white on preservation. It was labeled 

 L. rufus, a species with which it has long been confused though in 

 reality it is much more closely related to L. auhryi from which it can 

 be distinguished by the half-webbed outer fingers which in auhryi are 

 but a third webbed.

The largest example (No. 22096) of this widely distributed species in 

 the above series measures 48 mm. The variations of these specimens 

 have already been dealt with by Stejneger in the citation given.

 1 (U.S.N.M. 43092) Nairobi, K. C. (Sm. Afr. Exped.) 1909. 



The largest (No. 40755) of these three narrow-mouthed frogs meas- 

 ures 52 mm. from snout to vent. No. 43092 has a darkly pigmented 

 throat which Noble has stated is characteristic of breeding males.
