98. *Rhynchops flavirostris (Vieill.). 
This remarkable-looking bird was first seen at Wad- 
Habushi on March 18th, and a few arrived at Shendi on 
their northward journey on March 23rd. During the day- 
time they sit on an isolated sandbank or on a rock in the 
middle of the river ; in the early morning and evening they 
fly rapidly over the water with a very graceful skimming 
action. They are very wary, and we did not succeed in 
obtaining a specimen. 
99. Chenalopex iEGYPTiACA (Briss.). 
395 c?,407 c?,408 ?. 
Egyptian Geese were very common all along the river, 
generally being seen in pairs. They make a great noise 
Avhen they come out of the crops in the early morning. 
100. *Dafila ACUTA (Linn.). 
Pintails were often seen in large flocks flying down the 
ri ver. 
101. "^Nettion crecca (Linn.). 
Three Teal were once seen. 
102. Pterocles senegallus (Linn.). 
213 c^,214 c^,215 ?,379 ?. 
This large Sand-Grguse was very rare at Shendi com- 
pared with the next speeies. It was never seen in company 
with P. exustus, and seemed to prefer thick bush rather than 
the more open desert. The natives distinguish between the 
two birds, and call this one " Gutta Dahowi.^^ 
103. Pterocles exustus Temm. 
157 6, 216 6 , 218 6 , 261 6 , 310 6 , 156 ?, 217 ? ,

Our Shendi specimens may be regarded as being typical 
Pterocles exustus ; they do not agree with the form found on 
the White Nile by Mr. Witherby, and called by Mr. Hartert 
P. e. somalicus (^Nov. Zool. vii. p. 28) ; the latter is a much 
brighter, more sandy, and smaller bird. 
This Sand-Grouse was found in extraordinary numbers. 
It flies down to certain spots on the river to drink with
