EAST AFRICAN REPTILES AND AMPHIBIANS 29 



of No. 16755) entering the orbit. Stejneger has ah-eady discussed 

 in detail the variations presented by the two uniformly brown 

 Kilimanjaro reptiles. 



Uniformly black snakes are listed above from Budonga Forest, Ug., 

 Kaimosi, Kakumega, Kenya and Mbunyi in Kenya Colony. Those 

 with rhombic pattern are from Guaso Nyiro and Aberdare Moun- 

 tains in Kenya and from Morogoro in Tanganyiki Territory. A very 

 pinkish form with transverse dorso-lateral stripes from Morogoro, 

 T. T., and Lumbo, Portuguese East Africa. 



The Mbunyi snake, measuring 867 (763 + 104) mm., appears to be 

 the largest.

4 (U.S.N.M. 62908-11) Morogoro, T. T. (Loveridge) 1916-17. 



Mid-body scale rows, 191; ventrals 204 to 229; subcaudals, 67 to 

 75; labials, 8, the third, fourth, and fifth entering the orbit except 

 on the right side of No. 62908, where there are 9 labials, with the 

 third, fourth, and fifth entering the orbit. In No. 62910 the upper 

 temporal is divided on both sides. For size see reference given above. 



These snakes, as also others from Lumbo, were captured in dry 

 scrub country on reddish volcanic soil (Morogoro) or absolute sand 

 (Lumbo); they are not associated with forest, nor have I even seen 

 one in a bush, though they can undoubtedly climb. As one might 

 suppose, they are nocturnal, emerging just after sunset.
