 slight and some intermediate forms have been noticed. 

 According to Capt. Alexander, our subspecies {d) does not

The P. rueppelli (Riippell's Parrot) is also included. 



3. " On an unnamed Species of Owl from South Africa.'' 

 By W. R. Ogilvie-Grant. 

 The late Von Erlanger separated the northern form of 

 Scops leucotis^Asio leucotis (ranging from Senegal to Abys- 

 sinia and Somaliland) from the southern form met with in 

 S. Africa. Von Erlanger named the northern form Asio 

 leucotis nir/rovertex, but retained the typical name Asio leucotis 

 leucotis for the southern species. Temminck, however, in 

 1824 in naming the typical form originally from Senegal had 

 used the nomenclature Strix Inuvfis. Consequently the 

 northern form must retain the typical name, i. e. Asio (or, as 

 is now recognized. Scops) leucotis, and the southern form 

 must be re-named. The northern form will therefore be 

 known as Scops leucotis and the southern form as Scops 

 erlangeri. The separation of the two species is based upon 

 the southern form having the dark bars on the primary quills 

 and tail-feathers much wider and less numerous than in the 

 northern species and in lacking the uniform black patch on 

 the crown, all the feathers of that part, even in the darkest 

 specimen, being mottled with black and white.
