IS94-] 293 [Annual Meeting. 
The total number indexed is 30 serials, 333 volumes ; the 
current volumes of the serials reported on last year are indexed as 
received. 
The new cases in the back library have somewhat relieved the 
overcrowded condition of a part of our shelves and enabled us to 
make a beginning towards a system of shelf classification which

discouraging rearrangement every few years. 
Publications. 
One number of the fourth volume of the Memoirs, containing 
Dr. Charles S. Miiiot's Bibliography of Vertebrate embryology 
(128 pages), was issued last November. 
We have also distributed part 1 of the 2<)th volume of the 
Proceedings, and 104 piiges towards the second part are printed ; 
this includes the copy of all papers in the hands of the Publishing- 
Committee to date. 
The distribution of the first ])art of the new volume of Occa- 
sional papers printed last year was unexpectedly delayed until 
November on account of difficulties in the preparation of the two 
special maps. 
The repairs in the room used for the publications of the 
Society offered an opportunity for their rearrangement and more 
compact storage which is nearly completed. 
Walker Prize. 
The subjects announced for the annual award of the Walker 
Prize were as follows : — 
1. The relations of inflorescence to cross-fertilization illustrated 
by the plants of eastern Massachusetts. 
2. WhaV:, depths of formerly overlying rocks, now removed by 
denudation, may be inferred from the structure of various rocks 
in eastern Massachusetts? 
3. Experiments affording evidence for or against the theory of 
evolution. 
Notwithstanding the greater range in subject thus afforded, 
only one essay has been received, and in accordance with the rules
