^lNN ALS 



OF THE 



NEW YORK LYCEUM OF NATURAL HISTORY. 



With the present Number, — the concluding part of the Eleventh Volume,— 

 the publication bearing this name will close, in consequence of the change 

 recently made in the official name of the Society. It will at once be continued, 

 however, under the same management, with the title of the 



ANNALS OF THE NEW YORK ACADEMY OF SCIENCES. 



Volume I of the new Annals will begin with the year 1877. 



It is proposed, as before, to issue four numbers every year, each number 

 to consist of not less than thirty-two pages (octavo), with or without plates. 

 Price of Yearly Subscription, Two Dollars, payable in advance. 



The Academy has for sale a number of back volumes of the Annals of the 

 Lyceum, each containing twelve or more numbers ; the price per volume is 

 $4.00 with uncolored plates, or $5.00 with colored plates. 



The Academy has established a Publication Fund, contributors to which, 

 in the sum of $100 at one time, are entitled to all the Scientific Publications 

 of the Academy appearing subsequently to the payment of their contri- 

 butions.

N. B. All subscribers and correspondents are requested to inform the Chair- 

 man of the Publication Committee of any breaks or omissions existing in their 

 sets of the Annals of the Lyceum. Wherever it is possible to do so, the Acad- 

 emy desires to fill such omissions and complete such broken sets ; aud with 

 certain exceptions in some of the earlier volumes (I, II, and III), it can in 

 most cases readily be done.
