The following annual reports were read and referred to the Pub¬ 
lication Committee:— 
REPORT OF THE RECORDING SECRETARY. 
The Recording Secretary respectfully reports that the meetings 
of the Academy during the greater part of the year have been un¬ 
usually well attended and that the communications have been varied 
and interesting. The improvement is due in great measure to the 
plan of joint meetings of the several Sections with the Academy 
which was first carried into operation in March. A programme of 
the meetings was issued to the members with the effect of materially 
increasing the attendance. While communications from members 
of the Section to which the night is assigned have precedence, they 
do not exclude those from other members of the Academy and 
while there have been few meetings without some matter of special 
interest no difficulty has been experienced in affording opportunity 
to all who wish to obtain a hearing. Verbal communications have 
been made by Messrs. Leidy, McCook, Meehan, Ryder, Heilprin, Ives, 
Binder, Morris, Wingate, Goldsmith, Pilsbry, Foote, Koenig, Perot, 
Horn, J. B. Brinton, Rex, Hall, Woolman, Wilson, A. H. Smith, 
Hartzell, Willcox, Redfield, Dollev, Rothrock, Ford, U. C. Smith 
Campbell, Sharp, Jefferis, Skinner, Baker, Thomas, D. G. Brinton, 
Leffman and Aaron. 
Two hundred and twenty-eight pages of the Proceedings for 1888 
and three hundred and thirty-six for 1889 have been issued since 
the last report. The current volume will be illustrated by thirteen 
plates. In connection with the Academy’s regular publications 
mention should also be made of the Manual of Conchology which, 
since the death of Mr. Geo. W. Tryon Jr., in Feb. 1888, has become 
the property of the Conchological Section and has been promptly 
issued in two series under the editorship of Mr. H. A. Pilsbry. Of 
the Marine Series three hundred and twenty pages of text and 
seventy-five colored plates, and of the series devoted to Land Mol- 
lusca two hundred and seventy-nine pages and seventy plates have 
been issued during the year. It is gratifying to know* that the high 
standard established for the work by Mr. Tryon has been main¬ 
tained and that the subscription list is sufficient to more than pay 
the expense of issuing the w*ork.
