 fluttering white flags. 



25. Uganda Cob (adenota kob thomasi) .—This animal 

 is reported in a small German handbook from the east 

 shores of the lake and the country adjoining. Perhaps on

 in their distribution map. We looked into this matter 

 thoroughly, and are fairly certain cob are not to be found

 p. 563 — should be extended eastward to the heights above 

 Lake Natron. 



28. Steinbuck (raphicerus campestris neumani). — Com-
