latter another shot in the centre of the chest; but the re- 
markably strong beast darted away at an astonishing pace 
on three legs. I could not follow myself, but I sent Karsha 
after him, who gave him a long chase, and was finally 
successful in bringing him to ground, after putting two 
more bullets into him from my .577 express. The horns 
of the first animal measured twenty-two inches and a half, 
while those of the other were an inch shorter. They were 
the best water bucks I saw on Lake Rudolf, and belonged 
to the ordinary dark bristly haired variety, the Codms 
ellipsiprymnus, not to be compared to the splendid speci- 
men of the Codus defassa I shot on the Galana Amara, with 
horns over twenty-nine inches long. There were many 
very pretty and interesting plants growing along the 
eastern shore of Lake Rudolf,-— one of these (Dozaldsonza 
stenopetala, Baker, 77), which I found near the northern end 
of the lake,' proving to belong to a genus new to science. 
Whistling ducks were plentiful, which was very fortunate 
for me, as they were about the only food that I cared to 
eat at the time. Besides these there were countless other 
birds, such as the secretary bird, herons, eagles, pelicans, 
Egyptian geese, cormorants, and the lovely red-breasted 
bee-eaters, which were to be found in flocks, hovering in 
the dense smoke over burning patches of grass, and catch- 
ing insects as they tried to escape from the flames. 
By the 12th of August we reached a very rough, hilly 
country, that made marching very difficuit. We were 
getting into the volcanic region. Camping at the end of 
a little bay, where the beach was stony and the water very 
clear, I tried some fishing, and found here the chromis 
which I had caught on lakes Abaya and Stephanie, and 
which is the best fish of the Nile in point of flavor. They
