Winwood (Capt. Tyler having recently died), and that the new 

 members of Council be the Rev. R. A. Bullen, Rev. A. Fuller, 

 Dr. W. Hind, and Mr. J. E. Marr, F.R.S. (The Report was adopted 

 nem. con.) 



Referring to the past publications issued by the Society, it appears 

 that they give to the annual subscriber more than an average of 

 280 pages of quarto letterpress, accompanied by an average of 

 38 quarto plates, with 700 figures in the plates and text, and yield 

 an average of 134 described species to each volume. This is 

 far and away beyond what has yet been accomplished by any 

 Continental Palasontographical Society for a subscription of one 

 guinea annually. 



If anyone desires to know how so much valuable scientific matter 

 can be obtained for so small a sum, we will reveal to the anxious 

 inquirer and would-be annual subscriber the secret. 



(1) The Authors of monographs are not paid for their contributions. 



(2) The Officers cheerfully give their services, so that the cost of 

 management is reduced to a mere bagatelle. 



(3) The Geological Society of London most generously gives to the 

 Palgeontographical Society room for their stock in its apartments at 

 Burlington House free of charge, and also allows them to hold their 

 meetings in its rooms. 



(4) So that almost the entire cost of the volumes issued is 

 confined to the drawing and printing of plates, to the setting up and 

 correcting the letterpress, and the printing, paper, and binding of 

 the annual volumes. 



We sincerely trust that, with the new volume, will also come 

 many new members, who will eagerly desire to obtain, not onhy the 

 newly printed "annual" as it appears, but ask for and secure the 

 back volumes, some of which may still be had (with a liberal 

 allowance for taking a series) on application to the Honorary 

 Secretary, the Rev. Prof. Wiltshire, M.A., F.G.S., 25, Granville 

 Park, Lewisham, near London, S.E.

 M.A., D.C.L., F.R.S., F.G.S., ; Prof. John Morris, F.GS. ; F. E.

IN the present review of the Dinosaurs, I have confined myself 

 mainly to the type specimens which I have described, but have 

 included with them other important remains where these were
