Reference : , a — tolerably abundant ; b — scarce, never many on 

 the same clay ; ab — occurring seldom, but abundant when present. 



The letter a does not necessarily indicate that the species is abun- 

 dant, but simply that several specimens were seen on several occa- 

 sions during the month. 



As it was not until the latter part of the year covered by this list 

 that I examined the two species of herring {Clupea) sufficiently to 

 distinguish them at sight, I have marked with an f those months in 

 whicli I think it likely that they occurred. 



The English names given are, when printed in ordinary type, those 

 by which the species is known among the dealers ; when printed in 

 italics they are proposed by the writer.
