THE FISHES OF NEW JERSEY. 87 



center of former. Before each abdominal fin a small tubercle. 

 Skin above blackish tinged with olive, with oblique bands and 

 other corresponding ones of paler on sides. Deep color of upper 

 parts not extending beyond lateral line of scutes. Sides reddish 

 mixed with violet. Abdomen white. Length 2 feet 9 inches, to 

 fork of tail. The Delaware. (Le Sueur.) 



I have never seen an example from the state. The detailed 

 account by Ryder will supply all our present information of this 

 and the common species. In the short-nosed species, according 

 to Ryder, the snout is proportionately wider at the base and little 

 or no difference between its form in the young and adult; no 

 smooth area on top of head of young, which is also less deeply 

 concave; small dermal plates between dorsal and lateral rows 

 of scutes never tending to form oblique rows; smaller dermal 

 ossifications never tending tO' become lozenge-shaped except on 

 sides of upper lobe of caudal fin; dorsal lateral, and ventral 

 scutes not so closely crowded together/ few in number and with 

 no' preanal plates ; skin almost smooth in comparison ; mouth 

 very wide; fin formulae with much fewer radii; lower caudal 

 lobe long; viscera nearly black when exposed, and general color 

 reddish-brown. 



Dr. Dahlgren has met with small examples, probably this 

 species, nearly 2^ feet in length, in the shallow water at the 

 island by Trenton in the Delaware.

Order RHOMBOGANOIDEA. 



The Gar Pikes. 



Though known by many fossil forms this order contains but a 

 single living family which I call the Psallisostomatidcc {==Lepid- 

 osteidce auct.).
