* Mr. Ogilvie Grant has recently proposed to rearrange the species of this 

 genus (Bull. B. O. C. xii, p. 36, 1901). He recognises three species in South 

 Africa I. erythrorhynchus found in west and north-east Africa, and 

 extending to Natal : I. viridis also in Natal and the Colony : I. dama- 

 rensis from Damaraland. They are distinguished by him as follows : 



a. Back metallic green. 



a 1 . Tail longer, 9 to 10 ins ; white spot on the 



quills, 0-9 to I'l in width ........................ I. erythrorhynchus. 



b 1 . Tail shorter, 7 to 8 ins ; white spot on the 



quills, about 0'5 in width ........................ I. viridis. 



b. Back sooty-black, with a purplish-bronze gloss ... I. damarensis.
