lamented friend Dr. John Anderson, who spared no trouble to ensure its success, 

 and for the interest and advice continued to me by Mrs. Anderson, whose name is 

 associated with her husband's beautiful work on the land Vertebrates of Egypt. 



I beg to thank Lord Cromer for the continued interest he has shown in the 

 Survey, to which he has alluded in several of his Reports. 



To Dr. Keatinge I wish to convey my thanks for all the trouble he has taken 

 in the management of the business part of the Survey, and of the publication of its 

 results, as well as for much personal kindness. 



To Prof. Flinders Petrie I am indebted for assistance in the matter of the 

 representations of fishes by the ancient Egyptians, and for access to the library under 

 his care at University College ; also to Mr. Hilton Price, Mr. F. LI. Griffith, and 

 Mr. W. L. Nash in connection with Egyptology ; and my acknowledgments are due 

 to the Reverend Fathers of the Abbey of Maredsous for allowing me to keep for seven 

 years their (unfortunately incomplete) copy of the rare illustrated book of Rifaud, 

 ' Voyage en Egypte/ the only great work on the Nile fauna, containing many coloured 

 pictures of fishes, not in the library of the Natural History Museum. 



And, finally, my thanks are tendered to my talented artists, Messrs. P. J. Smit 

 and J. Green, for the pains they have taken on the illustrations.
