EAST AFRICAN REPTILES AND AMPHIBIANS 33

 my beUef, without verifying my impression by a search through the 

 somewhat voluminous records of tliis species. 



Mid-body scale rows, 17; ventrals, 153 to 169; subcaudals, 96 to 

 111; labials, 8, the fourth and fifth entering the orbit. The largest 

 snake (No. 49217) measures 1,185 (791+394) mm.
