EAST AFRICAN REPTILES AND AMPHIBIANS 67 



Admittedly, the two lizards present a strikingly different appear- 

 ance as regards color, but it hardly seems advisable to recognize 

 reptiles as full species without anything more tangible than a color 

 pattern to distinguish them. On the other hand it would be prema- 

 ture to place zecU in the synonymy of major and it seems advisable 

 to leave its present status uncertahi until we arc in possession ot more 

 adequate eeries and distributional data. 



In passing it might be remarked that while the Kenya hzard 

 m S N M 42216) might be matched in its belly coloring by typical 

 major, the Dodoma reptile (M.C.Z. 18313) has a dusky belly with 

 light lateral Imes precisely similar to a Transvaal specimen oiG^ 

 grandis in the Museum of Comparative Zoology. This species which 

 Boulenger described from a Zululand example, is distinguished by 

 possessing two scale rows more than G. major has across the back. 

 The dorsal coloring of the Dodoma lizard is also intermediate between 

 that of the Kenya and the Transvaal reptiles for m the latter the 

 "yellow spots," such as one finds in typical zecU, have so spread over 

 the scales as to ehmmate the browa in extensive areas.
