50. COTILE MINOR Cab. 
Ill c?,288 c^, 292 (^, 336 c? , 178 (sex?). 
There is a considerable diflPerence in size in these specimens. 
These little Martins were fairly numerous at Shendi, 
frequenting the river-banks either singly or in small parties 
just as our Sand-Martins do. On March 25th a colony of 
from fifteen to twenty pairs was found nesting in a sandpit 
on the brink of the river. The holes were horizontal and 
were about two feet long. One nest contained five eggs 
slightly incubated : the eggs are pure white ; one of them 
measures 16 x 125 mm. 
51. ^CoTILE RIPARIA LiuU. 
Sand-Martins were often seen on the river-bank, sometimes 
in company with the last species. 
52. HiRUNDO RusTicA Linn.

Chimney- Swallows were occasionally seen at Shendi. 
Our specimen was shot on March 26th, when it must have 
been on migration. 
53. HiRUNDO SMiTHi Lcach. 
267 cT, 317 (^,316 ?. 
This beautiful Swallow was very rare at Shendi, two or 
three pairs only frequenting a spot where the mud bank, 
harder than usual, projected as a little cliff into the river. 
A few pairs were also seen in a similar situation at Wad- 
Habushi, fifty miles further south. A shrill wailing cry is 
uttered by both males and females. 
On March 11th a nest containing three eggs was found in 
a crevice between two strata of the low cliff" above mentioned. 
The eggs are pure white. 
54. HiRUNDO ^THiopiCA Blauf.

Our solitary specimen of this Swallow was the only one 
seen.
