THE OOLOGISTS' HAND-BOOK 



FOR 1891. 



IT WILL CONTAIN OVER 150 PAGES OF VAL- 

 UABLE INFORMATION. 



It is with great pleasure that I am able to announce that the Mss. 

 for a new Oologists' Hand-Book is nearly ready for the printer and, 

 that under ordinary circumstances it will be ready for delivery 

 early in June. The new Hand-Book, for the money, we think will be 

 •one of the most valuable works for one interested in birds, ever pub- 

 lished. Our old '85 edition was issued as our catalogue — Our new '91 

 edition will not be a catalogue at all, but simply and purely a Collec- 

 tors' Hand-Book in the fullest sense of the word, and will contain, at 

 least 150 pages, each teeming with valuable information. It will also 

 contain two or three full page plates and many illustrations. The size 

 of the pages will be about 6x4 inches, making a volume that can be 

 conveniently carried in the pocket. Two editions will be issued, one 

 in paper covers at 50c per copy, and the other in flexible leather 

 at 75c. 



WHAT IT WILL CONTAIN. 



It will give the common and scientific name of every North Amer- 

 ican bird known at the date of going to press. These names will be 

 numbered, arranged and given according to the A. O. U. nomenclature, 

 they will also be divided and sub-divided into the orders and families 

 which they belong. It will give the numbers of each species as used 

 in Bidgway's nomenclature of 1881 and those uSed by Coues' in 1883. 

 It will give the value of the eggs of over 600 species and sub-species of 

 North American birds, as fixed by some, of the most competant Ameri- 

 can Oologists, at date of going to press, this fact alone making ic inval- 

 uable to collectors, as a basis on which to make exchanges. It will 

 give the breeding range of each species. It will give a considerable 

 information about the nest of each species. It will give the shape, 

 color, markings and size of the eggs of each species and will also state 

 the number usually found in a set. It will also mention some of the 

 more common local names by which each species is known in different 

 localities. It will also give a considerable information on the collecting 

 and preparing of specimens for the cabinet and will have something to 

 say about making cabinets, making exchanges, packing, etc., etc. It 

 will also tell how to make a good bird skin, and many other useful 

 hints and items, most of which will be well illustrated.
