along the back near the tail, by its smaller teeth, and the 

 slighter difference between the jaws. It appears on our shores 

 at the same time as the gar-fish, and is perhaps found more 

 frequently among the pilchards, often hampering the netsmen 

 by frightening those timid fish. It eggs are said to have the 

 same filaments as those of the gar-fish, and also to develop in 

 much the same way, and the larval forms of both are also 

 compared ; but little study appears to have been given to 

 either. A skipper of 18 in. would be a large example, and 

 in Cornwall one meets with more of about half that length.
