VOYAGE ON WHITE NILE

are found save in Upper Sudan. Though more than fifty 
years have passed since the existence of these two 
antelopes was first reported, yet little even to-day is pre¬ 
cisely known of their biology; indeed, it was only yester¬ 
day that the first correct details of their status and life- 
histories were partially rescued from chaos by Col. 
Roosevelt’s American Expedition of 1909-10. The two 
Sudan antelopes in question are—(1) The white-eared cob 
(Adenota leucotis) on the steppe; and (2) the saddle- 
backed lechwi (Onotragus megaceros) on the marsh. The 
possible third is a duiker of sorts. 
A Passing Flight of “Whistling Teal.” 
Such a record is creditable neither to British-African 
hunters nor (in yet less degree) to British science; hence 
the author hopes that both hunters and zoologists alike 
will take in good part the little lecture he addresses to 
them on this text on a following page. 
As regards my friends the hunters—that is the 
privileged few who enjoy personal contact with the bigger 
game of the world—I suggest that it is nowadays up to 
them all to bring home—not merely “heads” for their 
private collections—but such critical and accurate informa¬ 
tion as in them lies to collect and formulate; since to 
succeeding generations no such opportunity may be 
available.
