2 (U.S.N.M. 63511-2) Kafue River, Rhodesia. (Raven) 1919. 



The single spurred male (No. 20075) measures 173 (82 + 91) mm.; 

 the largest (No. 6351 1) of the four large females is 315 (162 + 153) mm. 



Gunther based his description of isahellinus on a single specimen 

 received from Nyasaland which he differentiated from dilepis by the 

 large scutes of the occipital flaps and in the description one notes that 

 "the distance between the commissure of the mouth and the extremity 

 of the casque is considerably longer than the length of the mouth"; 

 also "the scutes on the crown are flat, not tubercular." The second 

 and third points do not distinguish it from dilepis as in any large series 

 from East or West Africa scutation of both types may be found and 

 the relative distances between commissure and casque agree with 

 isahellinus. Werner in 1902 identified Boettger 's ruspolii from So- 

 maliland with isahellinus and specimens of the large scaled type have 

 been recorded from Meru in Kenya by Lonnberg and from Gulwe 

 and Dodoma in Tanganyika by myself.^^ I have recently reexamined 

 part of a large series from Dodoma and found examples with 4, 5, 

 and 6 scutes (isahellinus had three). The difference between these 

 Dodoma and Morogoro dilepis and West African dilepis is well 

 marked, but there seems to be no difference between West African 

 specimens and those from the Tana River, Usambara Mountains,
