NO. 7 wade: EASTERN PACIFIC APODAL FISHES 187 



and the fourth pore at the anterior end of the labial flange. A short 

 series of pores behind posterior edge of eye. Three pairs of pores below 

 tip of mandible, followed by a series of eight pores along underside of 

 lower jaw and throat. Inner lip with a finely fringed edge extending 

 longitudinally between outer lip and maxillary tooth band. 



Maxillary teeth in a narrow band anteriorly, tapering to three irreg- 

 ular rows laterally. Laterally two outer rows of maxillary teeth closely 

 appressed, and separated from the third and inner row by a narrow inter- 

 space. Teeth of outer row pointed, straight, slender, mostly hidden in 

 membrane at base of second row of teeth. Teeth of second row close set, 

 slightly enlarged, pointed, and a little curved. Teeth of inner row small, 

 blunt, irregularly placed. Vomerine teeth in an ovate patch of small, 

 pointed teeth. Maxillary teeth closely united to vomerine teeth at the 

 head of the patch. Premaxillary teeth numerous, similar to vomerine 

 teeth but slightly larger, placed before symphysis of lower jaw, and 

 separated from maxillary teeth by a narrow interspace. Mandibular 

 teeth similar to maxillary teeth. Tongue well developed, edges free 

 laterally and anteriorly. 



Color in alcohol dull olive bufif dorsally, shading into olive buflf along 

 mid-line of sides; underside of head and abdomen dark gray. Dorsal 

 and anal fins light olive bull. Pectoral fins pale. Opercle and nape 

 shaded with darker. 



This species differs from C. labiatus in the more anteriorly inserted 

 dorsal fin, shorter pectoral fin, more anterior insertion of the posterior 

 nostril, narrower isthmus and different placement of the lateral maxillary 

 teeth. The development of the labial flange of the upper lip is greater 

 than in C. labiatus, and the hollowed-out area beneath the flange is not 

 divided into two parts by a vertical partition. 



Genus ALLOCONGER Jordan and Hubbs 



Alloconger Jordan and Hubbs, 1925, p. 195 (type by original designation 

 Leptocephalus flavirostris Snyder) . 

 Body elongate, tail much longer than head and trunk. Head large, 

 subequal to trunk. Dorsal origin width of gill-opening before pectoral 

 base; well developed, confluent with anal around tip of tail. Pectoral 

 fins well developed; ventral fins absent. Snout projecting only slightly 

 beyond premaxillary teeth. Anteroventral mid-line of snout smooth, 

 without a keel or pocket. Anterior nostrils tubular, directed downward, 

 placed on lower surface of snout beside premaxillary teeth, just within
