of Giinther and the H. unifasciatus of all the American local 

 lists. The H. roherti of Cuvier and Valenciennes is very scantily 

 described. It is, however, related to H. unifasciatus, and is said 

 to have the lower jaw longer than in H. richardi or H. picarti. 

 We therefore identify it with this species, with this element of 

 doubt, that there is no other record of the slender form 

 south of Central Florida. This species occurs also in the Gulf 

 of California. Specimens from Charleston and from Mazatlan 

 are described by Jordan and Gilbert, as having the anterior rays 

 of dorsal and anal, and the upper and lower rays of caudal jet- 

 black, but no other difference from the usual form was noted.
