EAST AFRICAN REPTILES AND AMPHIBIANS

The measurements ol the various types are significant and I imagine 

 that an examination of the vomerine teeth of the young macrops 

 wouJd show them to be rounded as in albescens and not in obhque 

 rows as in the adults of macrops. In the series of the Museum of 

 Comparative Zoology the development ot these teeih is well shown. 



The other differences contained in the lengthy descriptions are too 

 obviously trifling variations to warrant detailed discussion.

In all respects a typical male, it measures 49 mm. The tibiotarsal 

 articulation of an adpressed hind limb reaches the tympanum which 

 is quite distinct. The very distended stomach holds two solpugids. 



Ahl has described from Togoland a young (22 mm.) frog which he 

 states is "related to L. bocagii and L. verrucosus from both of which it 

 differs in (1) longer tongue, (2) broader interorbital space, (3) some- 

 what longer hind limb" (translation). The material in the Museum 

 of Comparative Zoology exhibits the following variations: 



The localities from whence these specimens came are Guaso Nyiro 

 district, Kenya Colon}^; Faradje, Belgian Congo; Nairobi, Kenya 

 Colony; Sagayo, Mwanza, Tanganyika Territory. 



Noble has already foreshadowed the probability of L. ancMetae 

 (Bocage) having to be united with L. bocagii and I entireH agree 

 with his remarks.^'' His material, however, was undoubtedly iden- 

 tical with Nairobi specimens identified for me by Miss Procter; one of 

 his Faradje frogs is now M.C.Z. No. 6614 referred to above. The
