THE ALGERIAN SAHARA. 61 
reckon the Garganey Teal; albeit, I flushed a brace of 
Ducks on April 4th, which looked uncommonly like them, 
ADDENDUM. 
In the Ornithological Journal—the “Ibis”—edited by 
Salvin, and published by Van Voorst, I have given at pages 
68, 289 of the Ist vol. of the 3rd series, an extended account 
of all the species I positively identified. The following 
slight rectifications require to be made. 
No. 31. Ciuclus aguaticus should be Cinclus albicollis 
(Vieill). 
No. 36. Dromolewa leucopygia is to be united with No. 37, 
D. leucocephala.

a female at Berryan, on the 30th of April, 1870.

Gardaia oasis, 26th of April.”

be “Common in Spring.”

Laghouat,” should be “one shot at Laghouat, May 4th, 
1870.”

a female between Tibrem and Laghouat, May 3rd.

Tibrem and Medea.
