442 Mr. B. Alexander —An Ornithological 
being pushed into the water till fish is taken. It is a very 
careful bird and difficult of approach. 
223. Pelecanus onocrotalus Linn. 
Found on the lower reaches of the river below the mouth 
of the river Shire. 
224. Hydrochelidon leucoptera (Meisner & Schinz). 
Migratory on the Zambesi. First observed on Sept. 27 
at Chicowa (a party of five). At Zumbo, on Nov. 11, for 
two days immense flocks kept passing down the river, mottling 
the air white with their bodies. Again, on Dec. 30 and 
Jan. 2, large flocks were observed beating down the river. 
Three females obtained in winter-dress. 
225. Bhynchops flavirostris Vieill. 
Not common. On the Chicowa flats we came across a 
small party breeding on a sandbank (Sept. 27). We found 
a nest containing three eggs (much incubated) in a deep 
capacious hole scratched in the sand. 
Description of the eggs .—Average measurements P57 x 1*2. 
Ground stone-colour, blotched and spotted all over with 
light umber-brown and underlying markings of purplish 
brown. These birds are fond of congregating over some pool 
towards nightfall, flying to and fro catching their prey. 
The flight is steady, the wing-beats being very marked, 
the bird skimming the water the whole time. 
The note is a loud, harsh “ kip,” constantly repeated. 
226. Larus cirrhocephalus Vieill. 
Single individuals frequently observed all along the river. 
On our way up to Chindi we saw big flocks at Durban, in 
Delagoa Bay, and at Inhambane. 
Adult S (Senna, July 25, 1898). Iris straw-colour; bill, 
legs, and feet dark crimson. 
227. Phcenicopterus roseus Barr. 
Flocks seen in July on the Zambesi deltas, but not beyond 
the tide-influence. During our stay, on July 9, at Inham¬ 
bane, Flamingoes were numerous. Towards evening, at low 
tide, a vast tract of land in the bay was the resort for flocks
