with a scanty lining of grass. They were just such as 
this bird might build; but while we saw only fonr or 
five birds in a day, we were certain to see at least five 
hundred of these nests. In no instance did they contain 
eggs.

Shendi must be very nearly the northernmost limit reached 
by this species, as at the Pyramids of Meroe, about forty 
miles further north, though the country is admirably suited 
to it, not an individual was to be seen. It is a conspicuous 
and noisy bird, in habits very like the Raven, but rather 
more gregarious. A nest containing three fresh eggs was 
found in an acacia in the desert on March 23rd. The 
eggs resemble those of Corvus corax, but are much smaller, 
measuring only 44*5 by 30'5, 44 by 305, and 41*1 by 32'5. 
26. *CoRVUS uMBRiNus Suud. 
This Crow was rarer than the preceding species, and very 
much more shy in its habits. 
A nest containing one hard-set e^g was found on March 8th, 
The egg resembles that of C. scapulatus, but it is not so 
green and the markings are paler. It measures 44 by 
3] "5 mm. 
27. "^CoRVUs AFFiNis Rtipp. 
A few pairs of these Crows were occasionally seen on the 
rocky hills in the desert; but they were always very careful 
to keep out of range of a gun. 
28. Lanius nubicus Licht.

The Nubian Shrike was common at Shendi. It was 
generally to be seen in pairs, and was exceedingly bold in 
resenting the approach of any intruders. On two occasions 
we observed the old birds feeding the young, which Avere 
scarcely able to fly, but no nests were found. 
29. Lanius isabellinus Ehrenb.

Only three specimens of this Shrike were seen ; it is a shy
