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 formule 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.

Though known by many fossil forms this order contains but a 
single living family which I call the Psallisostomatide (==Lepia-
