A single specimen, a gravid female, was found in the 

 Chirinda Forest, S.E. Mashonaland, altitude 4500 feet, by 

 ]\Ir. Guy H. K. Marshall, and presented by him to the 

 British Museum. 



The discovery of a species of the genus Rhampholeon south 

 of the Zambesi is one of very great interest. The Chiriuda 

 Forest, ]\Ir. Marshall informs me, has a tropical insect-fauna 

 quite dif^tinct from that of the surrounding districts. Its 

 reptile and batiachian fauna, when explored, is likely to afford 

 further startling additions to South-African herpetology.
