NEW, EARE OE LITTLE KNOWN SCOMBROIDS. No. 1. 

 BY HENRY W. FOWLER. 



The present paper is one of a series now in preparation, which will 

 be intended to give accounts of the more interesting Scombroids con- 

 tained in the collection of the The Academy of Natural Sciences of 

 Philadelphia. While a few of the species appear to be new, others are 

 rare, and some are of value in establishing identifications of older 

 naturalists. I have framed complete descriptions of some species 

 which have at all times needed elucidation, while a number of others 

 are supplemented with notes. Changes in nomenclature which appear 

 necessary are given. In such cases some are due entirely to a rigid 

 adherence to the original orthography. In the introduction of several 

 new subgenera it may be remembered that where transitional forms 

 occur, like those in the older conception of Caranx, the better defined 

 groups, possibly of different lines of descent, had, at least best be 

 indicated even if only provisionally.
