Neoconger, GIRARD, U. S. Mex. Bound. Surv., Ichth., 77, 1859, (mucronatus). 



Body moderately elongate, not whip-like. Pectoral fins present ; verti- 

 cal fins rudimentary, passing around the tail, towards the end of which 

 they are more developed; dorsal beginning just before vent. Cleft of 

 mouth extending beyond the small eye ; maxillary teeth slender, in several 

 series ; vomerine teeth uniserial, forming a patch in front ; tail not much 

 longer than rest of body. Gill openings vertical, rather large. Two 

 species, (vtoc, new ; Conger.) 



a. Pectoral small ; Gulf of Mexico. MUCRONATUS, 593. 



aa. Pectoral well developed, 3^ to 4 in head ; Pacific Ocean. VERMIFOHMIS, 594. 



593. NEOCONGER MUCRONATUS, Girard. 



Head small, slender, pointed; upper jaw the longer; dorsal fin begin- 

 ning just in front of the vent, forming a membranous ridge until near the 

 tail, where it expands and becomes fin-like ; pectorals small. Dark red- 

 dish brown above, paler below. Coast of Texas. (Girard.) One speci- 

 men known ; the imperfect description not distinguishing it from N.
