REMARKS ON ADDITIONAL CHARACTERS TO THOSE 
RECOMMENDED BY THE BOARD. 
In Sample II two additional characters to those recommended by the 
Board were examined, namely, the relation of the posterior border of the 
maxilla to the orbit, and the number of pyloric ceeca. In the large sample 
it was found impracticable to examine the former character in addition 
to the Board’s characters, owing to the exigencies of time, but the pyloric 
ceca of all the fish in Samples III and IV have been preserved with their 
proper number, and can be examined and recorded at leisure. 
The examination of these characters 1s considered of equal importance 
to those recommended by the Board, since they are characters in which 
Clupea harengus differs from allied species.
