NEOCONGER, Girard 



Gen. Char. — Pectoral fins present ; dorsal and anal fins mostly reduced to a membranous ridge, uniting with the caudal, where 

 they are better developed. Snout tapering ; lower jaw shorter than the upper ; maxillar teeth exiguous, disposed upon multiple 

 series. A patch of similar teeth on the front of the vomer, and one series along its median line. Gill apertures lateral, rather 

 large and vertical. 



NEOCONGER MUCRONATUS, Grd. 



Spec Char. — The largest specimens observed are about twelve inches in total length. The head is small, slender, narrow, 

 and pointed; the upper jaw projecting beyond the lower. The gape of the mouth is horizontal, its angles extending beyond 

 the orbits. The eyes are very small, sub-elliptical. 



The posterior nasal aperture is placed near the anterior rim of the orbit, whilst the anterior 

 one is situated on the side and near the apex of the rostrum. The vent is situated somewhat 

 nearer the extremity of the snout than the posterior edge of the caudal fin. The dorsal fin 

 commences a little way in advance of the vent, and, like the anal fin, it constitutes a mere 

 membranous ridge until about an inch and a half from the posterior extremity of the body, where 

 it expands, fin-like, and unites with the anal. The pectorals are small, sub-elliptical in their 

 outline, and broad at their base. 



The color is dark reddish brown above ; light reddish or dull white beneath.
