i 7 2 CRETACEOUS AND TERTIARY FISH. 



These examples all agree with Leidy's account and strongly 

 suggest the teeth of our existing barracudas. 



Formation and locality. Originally from the Miocene marl of 

 Cumberland County, it is very likely my nine examples are from 

 the same formation in Monmouth County (P. D. Knieskern). 

 Cope also had a single anterior tooth from the same formation 

 in the Thomas collection from Charles County, Md. 1 It seems 

 to agree, as much as its fragmentary nature will permit, with the 

 New Jersey material. Also two small teeth from Vincentown 

 [probably the Vincentown limesand or the Manasquan marl, 

 K.] (T. M. Bryan), may also belong to this species, though they 

 are somewhat more curved. 



Sub-Order BERYCOIDEI. 



THE BERYCOID FISHES. 



No suborbital stay. Shoulder-girdle and pharyngeals normal. 

 Vertebrae 24 to 30. Head with conspicuous mucous cavities. 

 Body naked or variously scaled, sometimes scales greatly special- 

 ized. Air-vessel with persistent duct in some forms throughout 

 life. Dorsal fin with few or many spines. Ventrals thoracic or 

 subabdominal, each with spine, usually seven branched rays, latter 

 varying five to ten, and in one group spine greatly enlarged, with 

 rays reduced in number. 



Usually six families admitted, mostly living fishes in tropical 

 seas, and three are also represented by extinct forms. 



Family BERYCID^E. 



Body oblong or ovate, compressed. Eye lateral, usually large. 

 Mouth wide, oblique. Premaxillaries protractile. Maxillary 

 rather large, usually with supplemental bone. Bands of villi- 

 form teeth on jaws and usually on vomer and palatines. Canines 

 sometimes present. Suborbitals narrow, not ensheathing cheeks. 

 Opercular bones usually spinous. No barbels. Gill-rakers mod-
