Both species of Herring-Gulls are occasionally seen on the 

 river at Giza, as well as on the flooded country. At a distance 

 it is not always possible to distinguish them, especially as 

 L. cachinnans is often as light on the mantle as L. argentutus, 

 but I have at times positively identified both forms, 



249. Larus fuscus. 



Larus fascus Shelley, p. 304. 



The Lesser Black-backed Gull is frequently met with 

 from autumn to late spring.

 Podiceps minor Shelley, p. 314. 



On February 14th, 1908, I saw a Grebe, which I believe 

 to have been of this species, on a pool close to the railway 

 between Cairo aud Helwan. 



Since the publication of the first part of this paper a 

 certain amount of additional information has come to hand, 

 and examples of several species not included in it have 

 been obtained by myself or my friends in the Province of 

 Giza. A few corrections in nomenclature are also advisable. 

 During June last I was enabled, by the kind permission of 

 the Hon. W. Rothschild and Dr. E. Hartert, to compai-e the 

 majority of my birds with the fine and well-cared-for 

 collection in the Tring Museum, and thus had the oppor, 

 tunity of comparing several of my skins with the types in 

 the Brehm collection. For this privilege, and also for their 

 kind help in identifying many birds which I have been 

 vmable to examine personally, I wish to record my best 

 thanks to Mr. Rothschild and Dr. Hartert. My best thanks 

 are also due to Dr. Sharpe and Mr. Ogilvie-Grant, who have 

 given me much help while working at my collections in the 

 British Museum. 



With the Editors' permission, 1 hope, at some future time, 

 to write an Appendix to the Birds of Giza, and thus bring 

 the list " up to date " as far as possible.
