318 REPORT OF NEW JERSEY STATE MUSEUM. 
interorbital space 41% ; fourth dorsal spine 2% ; fourth dorsal ray 
2%; second anal spine 3%; third anal ray 244; upper caudal 
lobe 1%; least depth of caudal peduncle 3; pectoral 1% ; ventral 
1%. Body compressed, predorsal region with median keel and 
other edges rounded. Profiles similar, back not elevated, and 
greatest depth falling about base of fifth dorsal spine. Caudal 
peduncle compressed, a trifle longer than deep. Head compressed, 
and profiles similar, or upper a little more inclined than lower. 
Snout a trifle longer than broad. Eye a trifle longer than deep, 
rounded, high, and about midway in head. Mouth small, terminal 
and a little inclined. Jaws about even, when closed. Maxillary 
small, well concealed above by preorbital, reaching front nostril, 
and its expansion equals vertical diameter of pupil, which is a 
little less than horizontal. Lips rather thin. Rami of mandible 
not elevated in jaws. Teeth in jaws minute, in narrow bands. 
No vomerine, palatine or lingual teeth. Tongue small, rather far 
back, short, rounded, fleshy and free. Nostrils separated, and 
close to front of eye. Entire margin of preopercle with weak and 
rather sparse serre. Edges of subopercle, interopercle, opercle 
and preorbital entire. Gill-opening extends forwards opposite 
posterior margin of pupil. Gill-rakers 8-++12, lanceolate, weak, 
and longest about 4 of filaments, which are about same of orbit 
horizontally. Isthmus rather broad and rounded. Scales mod- 
erately small, largest on costal region, and above lateral line in 
oblique series sloping to bases of dorsals. On caudal peduncle, 
both above and below in horizontal series similar to those on costal 
region and abdomen generally. Head, except lips and maxillary, 
more or less completely covered with small scales, in about 17 
series on cheek. Suprascapula covered with small scales. Dorsals 
and anals without scales, except narrow basal sheaths extending 
nearly their entire lengths. Greater portion of caudal, except 
posterior margin, covered with fine scales. Pectoral scaly at base. 
Ventral with’ a pointed scaly axillary keel 3% in appressed fin. 
Scales on chest and prepectoral region minute. Lateral line of 
simple tubes concurrent with dorsal profile and extending well out 
on caudal basally. Origin of spinous dorsal failing about midway 
in vertical between tip of snout and base of last spine, spines
