Herewith is issued Part IV. of Volume III. It contains the remaining portion of the Order 

 Accipitres, the Order Striges, and the commencement of the Order Steganopodes. The 

 figures of eggs, which are of the natural size, were reproduced by the heliotype process at 

 the Government Printing Office, from photographs of the specimens taken under the direction 

 of the Government Printer and the supervision of Mr. A. E. Dyer. As in the previous Parts, 

 the illustrations of birds are reproduced from drawings made by the late Mr. Neville Cayley, 

 who was also responsible for hand-colouring the Plates of Eggs in the coloured copies.
