REPORT OF PUBLICATION COMMITTEE. 



Hall of the Academy of Natubal Sciences, 1 

 Philadelphia, Dec. 3d, 1868. j 



The Publication Committee of the Conchological Section re- 

 spectfully reports its operations for the current year, as follows : 



Part 4 of Vol. 3 American Journal of Conchology, containing 

 "* 25 pp. and eleven lithographic plates, was issued in April, 

 completing the volume. 



Three Parts of Vol. 4 have been published, containing 172 

 pp. and several plates. The fourth Part is now in press, and 

 Part fifth, (completing the 4th Volume) will be made up from 

 the papers and reports presented this evening. Your committee 

 estimates that the current volume will include about 400 pp. of 

 text. All the accompanying plates, twenty in number, have 

 been drawn, and most of them are printed ; seven will be colored. 



In addition to the " Journal,'' your committee has issued 

 Parts 5 and 6 of the " Monograph of Terrestrial Mollusca of 

 the United States," completing that work. These Parts con- 

 tained 50 pages of text, illustrated by four lithographic plates. 



The circulation of the Journal has increased by fifteen addi- 

 tional subscribers and exchanges during the year, and that of 

 the Monograph was also slightly increased. 



In our last report we stated that we were engaged in examin- 

 ing and collating the copies of " Haldeman's Monograph of 

 Fluviatile Mollusca," presented to the Section by the author. 

 We have since concluded to issue a few copies of this work, 

 together with a continuation of the subject, so that the entire 

 work shall exhibit our present knowledge of these families. The 

 expense of this contemplated publication is already covered by 

 subscriptions received, so that there is good reason to believe 

 that the Section will realize a handsome addition to its trust 

 funds from Prof. Haldeman's donation. 



All of which is respectfully submitted, 



Geo. W. Tryon, Jr., Chairman.
