The white-cheeked turaco is one of the two species of its genus 

 entirely restricted to northeastern Africa, the other being T. ruspolii, 

 known from only a single specimen. T. leucotis has two very dis- 

 tinct races, the typical form found in Eritrea, central Ethiopia, and 

 Shoa; and an eastern race donaldsoni found in western Somaliland 

 and eastern Ethiopia from Harrar to the Webi Web and the Webi 

 Shebeli. In the typical form the crest feathers are bluish black 

 distally, while in doiialdsoni they are reddish terminally. Of the 

 latter subspecies I have seen but a single example; of the former, 

 11 have been examined. The measurements of these birds are as 

 follows: Male, wing 171-175, tail 183-186.5, culmen from base 

 23.5-25.0; female, wing 170-177, tail 175-188, culmen from base 

 22-24 millimeters. Reichenow "^ gives the following n^easure- 

 ments: Wing 175-185, tail 200-210, culmen 23-25 millimeters. It 

 will be noted that the data he gives for the tail length are consid- 

 erably different from tliose afforded by the series before me. I 

 can not account for the discrepancy, but can only suggest that 

 Reichenow 's figures are wrong.
