Heroibranchs with the four anterior vertebrae much lengthened; 

 bony plates anteriorly and especialh^ about the back ; an elongated 

 tubiform mouth ; abdominal ventrals with a spine and several 

 rays ; a small distinct spinous dorsal about the middle of the 

 body ; with the branchihyals and pharangeals mostly present, the 

 fourth superior branchihyal, and first and fourth superior pharyn- 

 geals only wanting.

Macrorhamphosids with an oblong body, graduating into the 

 caudal peduncle, straight back, and about seven dorsal spines. 



Type, M. scolopax = Gentriscus scolopax Linn., 1766. 



As Messrs. Jordan & Gilbert have recently shown (Proc. U. S. 

 Nat. Mus., V. 5, p. 575, 1883), the only species referred by Linnaeus 

 at first to the genus Gentriscus, was the G. scutatus (afterwards 

 taken as the type of Amphisile) , a.nd consequently Gentriscus can- 

 not be properly used as the designation of the present genus. The 

 name Macrorhamphosus, being the first applicable, although 

 imposed by mistake, may be used for it. It is unfortunate that 

 the change should have to be made, and, although fully con- 

 versant with the status years ago, I hesitated to propose it. 

 Nevertheless with such excellent authorities as Messrs. Jordan 

 & Gilbert to recognize its necessity, I no longer refuse to 

 accede to the change.
