REPORT OF THE COXCHOLOGICAL SECTION. 
The Recorder of the Conchological Section reports that the more 
important work transacted during the year has been the regular 
issue of the Manual of Conchology and the arrangement of the cab¬ 
inet in connection with the necessary study of mateiial as the several 
families have been reached. Four numbers of each of the two series 
of the Manual have been published, the parts of the marine series 
embracing the Turbinidse, Delphmulidse and portion of the Tro- 
chidie, while the parts of the second series devoted to the land mollusca 
treat of the Helicidae of the West Indies and South America. The 
former consists of 320 pages of text and 75 plates while the latter 
includes 279 pages and 70 plates. The Section has pleasure in ac¬ 
knowledging the efficient services of the editor, Mr. Henry A. Pils- 
bry, to whom belongs the credit of maintaining the standard of ex¬ 
cellence established bv Mr. Tryon. It is gratifying to be able to 
report that the work is more than self-supporting. The meetings 
held in connection with the Academy, in harmony with the sugges¬ 
tion adopted by the latter last spring, have been rendered interest¬ 
ing by communications from Messrs. Pilsbry, Baker, Heilprin, Ford, 
Campbell and U. C. Smith. At the meeting held Dec. 5th, the fol¬ 
lowing officers were elected to serve during the ensuing year :—
