{nodulosus, having nodules.) 



Family X. GONORHYNCHID^. 



Head and bodj^ entirely" covered with ctenoid scales; a barbel present 

 under the elongate, pointed snout; margin of upper jaw formed by 

 the short premaxilliary, which is continued downward as a thick lip, 

 in front of the maxillary. Jaws toothless; lips thickly fringed with 

 barbels. 



Doi'sal fin far back, opposite ventrals, short, like the anal. 



Pseudobranchite present; gill openings narrow. Air bladder absent. 



Branchiostegals four. 



A single genus with two or three species known among living fishes. 

 Several extinct genera are placed near Gonorhynchus. It difl:ers 

 strongly from all other herring-like fishes in having the head closely 

 scaled. 



18. GONORHYNCHUS Gronow. 



Gonorhynchus Gronow, Zoophylaceuin, 1763, (No. 199=6'. gonorJiynchus) . 

 Rhynchana Richardson, Voy. Erebus and Terror, 1846, p. 44 {greyi=gonor- 

 hynchus). 



The characters of this genus are included above. The single Japa- 

 nese species differs from Gotiorhynchus gotiorhynchus of the Cape of 

 Good Hope and neighboring waters in the deeper bod}^, longer head, 

 and a smaller number of fin rays. Gono7'hy/ichHS goiiorkynclms is 

 said to have the head about 5f in length, the dorsal 11 to 13, and the 

 anal rays 9. Gonorhynchus hrevis Kner, slender and short-headed, is 

 probably the same.
