NO. 7 WADE: EASTERN PACIFIC APODAL FISHES 185 



5b. Teeth of vomer extending backward in a single series to 

 below middle of eye; labial canal sending two or three 

 long bony processes downward and backward to support 

 the very extensible upper lip . . . JJroconger Kaup 



Genus GHILOGONGER Myers and Wade 



Chiloconger Myers and Wade, 1941, p. 65 (type by original designation 

 C. labiatus Myers and Wade). 



Body elongate, head roughly cylindrical. Body and especially the 

 tail compressed. Tail much longer than head and trunk. Dorsal origin 

 slightly behind gill-openings, confluent with anal around tip of tail. 

 Pectoral fins well developed, ventral fins absent. Snout abruptly de- 

 curved, slightly shorter than eye. Upper edge of gill-opening reaching 

 upper edge of pectoral base. 



Flange of upper lip developed into a short, broadly rounded flap, the 

 highest part of which reaches or covers the posterior nostrils. Maxillary 

 teeth in a narrow band of small, close-set, pointed teeth, closely united to 

 vomerine teeth anteriorly. Prernaxillary teeth separated from vomerine 

 teeth by a narrow groove. 



Labial canal present, extending backward above edge of upper lip to 

 beneath eye and upward around its posterior edge. Inferior, superior, and 

 interior walls bony, external surface covered by skin only. No bony 

 processes extending downward into lip from inferior edge of labial canal.
