254 Mr. C. H. B. Grant on a Collection of 



individual variation occurs in this little Owl, and I cannot 

 see any constant character sufficiently "well marked to 

 ■warrant separation into races, and therefore, without more 

 convincing proof, I must place Gunning & Roberts' names 

 as synonyms. 



The other named races of this Owl are t — Pisorhina 

 c. vgandcs Neum. J. f. O, 1899, p. 56 : North Uganda ; 

 P. c. leucopsis Hartl. Rev. Zool. 1849, p. 496 : Island of 

 San Thome ; P. c. icterorhyncha Shelley, Ibis, 1873, p. 138 :

 the head. 



[Irides rich yellow ; bill greenish horn ; feet dirty grey. 

 Stomach contained mice. This was the only specimen 

 seen, and was perched in a stunted thorn-tree.] 



In the * Ibis ' for 1906, p. 660, Mr. Ogilvie-Grant says that 

 Erlanger renamed the typical form, which statement is not 

 quite correct, and at the same time Mr. Grant gives a new 

 name to tlie southern race. 



I have carefully examined the series in the National 

 collection and agree with Mr. Grant that two races cer- 

 tainly exist, and 1 am by no means sure that a third will not 

 have to be recognised. 



The races are as follows :— 



Otus leucotis leucotis Temm. : Senegal. Represented 

 in the Museum by specimens from Gambia. 



Range. Gambia, Sierra Leone, Nigeria, White Nile, 

 Khartoum to Somaliland, and British East Africa.
