332 AMERICAN JOURNAL 



REPORT OF PUBLICATION COMMITTEE. 



Hall op the Academy of Natural Sciences, \ 

 Fhiladeljy/na, Dec. Isl, 1870. / 



The Publication Committee of the Conchological Section 

 reports its transactions for tlie year 1870 : 



Parts 3 and 4, Vol. Fifth, American Journal of Conchology, 

 containing together 125 pp. and four colored plates, were issued 

 Feb. 3d and May 5th respectively. Of the current (6th) vol- 

 ume, two Parts have been published, the dates of issue being 

 July 7th and Nov. 3d. These two parts contain 290 pp., illus- 

 trated by nine plates and numerous wood engravings. The 

 aggregate number of pages of the Journal issued is 415. 



Vol. 6th, Part 3d, is now in the printer's hands, and Part 4th, 

 completing the Sixth Volume, will embrace the papers and 

 reports presented for publication this evening. 



Besides the Journal, jonr Committee has published : 



" Catalogue of Recent Mollusca," Part 5, containing Margi- 

 nellidse, by John H. Redfield, and Melanidce, by Aug. Brot, 

 M. D. 110 pp. Nov., 1870. 



Monograph of the Fresh-water Univalve Mollusca of the 

 United States, by Geo. W. Tryon, Jr., Part 1, 82 pp., 6 colored 

 plates. July, 1870. 



The subscription list of the Journal has again increased, so 

 that it is nearly or quite self-sustaining, and, in congratulating 

 the Section upon this very satisfactory evidence pf the impor- 

 tance and value to oonchologists of its official publication, we can 

 reasonably anticipate that in the early future a reduction of the 

 subscription price will become practicable without involving the 

 Section in loss. 



Quite a number of complete sets of the Journal have been 

 sold during the year, so that our supply of the early volumes 

 has become scant. We recommend that the price for complete 

 sets be increased to six dollars per volume.
