Occasional Holes. 129 



species are recorded by Sclater as having been found. This 

 list must not, of course, be regarded as in the slightest degree 

 or in any way exhaustive, but is in practically every case 

 only typical of the South African localities in which the 

 bird referred to has occurred, and only refers to actual 

 records, either published or personally handed to Mr. Sclater. 

 Secondly, I give details of all the South African breeding- 

 places of the different species as recorded by Sclater ; this 

 list of breeding-places, unlike the list of recorded localities, 

 probably is, so far as Mr. Sclater's information when he 

 wrote his manuscript some three years ago is concerned, 

 doubtless exhaustive of all the knowledge he had then been 

 able to obtain on the subject. It will be observed that these 

 details and observations are extremely scanty. 



" Below this list I append a few cases which have come 

 under my personal notice, with which I can supplement 

 Sclater's list.
