This species, apparently one of the commonest of 

 the Leptocephalids met with near Messina, is repre- 

 sented by no less than twenty two individuals in 

 the collection, all from that locality, some of them 

 procured by Prof. Theel and Dr. Appellof, some by 

 Dr. Bovallius. It might perhaps seem superfluous 

 to record the dimensions of so many individuals be- 

 longing to one and the same species, but since the 

 proportions of the different parts of the body to one 

 another are of such great importance in differentiating 

 the species, particularly in the family of the Leptoce- 

 phalids, it cannot but be of great interest and mo- 

 ment, seeing we have at our disposal a large selec- 

 tion of individuals belonging to the same species, to 

 observe how constant these proportions in reality 

 prove to be.
