APPENDIX. 
Tue following pages are intended to be filled up by the 
field naturalist as specimens come under his observation, 
thus providing a permanent record of the relative fre- 
quency and average lengths of the various species in the 
locality referred to, and a means of comparison with the 
observations of others. 
(The author would be grateful if observers would com- 
municate to him the result of their observations from time 
to time.)
