Publications. 
Twelve papers, completing volume 27, and one paper, the first of 
volume 28, of the Proceedings have been issued during the year. 
The large number of plates, twenty-six, illustrating volume 27 is 
noteworthy and is the result of publishing two papers in co-operation 
with the Museum of comparative zoology. 
The separate publication and prompt distribution of each paper 
has proved satisfactory to our contributors and our exchanges.
