EELS OF THE GENUS CONGER — KANAZAWA 255 



Diagnosis: Two rows of teeth in jaws; pectoral rays 19 to 21; 

 origin of dorsal fin from 10 percent behind pectoral tip to 40 percent 

 anterior to pectoral tip; length of head 163 to 184; ossification not 

 bridging across sensory canal of preorbital bone. 



Description: Tip of snout to origin of dorsal fin 199 to 222; length 

 of pectoral fins 48 to 60; upper jaw (to rictus) 52 to 59; dorsal rays 

 288 and 300, anal rays 217 and 229 in two specimens; vertebrae 137 

 to 147 (50 precaudal and 87 caudal in one specimen) ; two rows of 

 teeth in jaws laterally, inner row from one-half to whole length of 

 outer row; 39 to 53 compressed teeth in upper jaw, 40 to 52 in lower 

 jaw; premaxillary tooth-patch wider than long; one supratemporal 

 pore; upper edge of gill opening near midpoint of pectoral base, 

 slightly closer to upper edge than lower; rictus of jaw below middle 

 of eye; length of head into trunk 1.10 to 1.39, head and trunk into 

 tail 1.48 to 1.60; ossification not bridging over sensory canal of 

 preorbital bone. Additional counts and proportional measurements 

 are recorded, in tables 1 to 6. (Counts and measurements of the types 

 were made by Dr. J. Bohlke at Stanford Museum.) 



Geographical range: From Sagami Bay southward to Hakata, 

 Kiushu, Japan, to Fusan, Korea. 



Kemarks: Jordan and Snyder (1901, p. 849) had two other species 

 mixed with the type series of Leptocephalus erebennus : one specimen of 

 Conger myriaster and three of C. jordani. Jordan and Snyder recog- 

 nized the differences in the head and trunk proportions in theh* key; 

 however, in their description the proportional measurements were 

 mixed. 



This species is closely related to C. esculentus from the West Indies. 

 For differences see key (p. 231). 



The number of pectoral rays distinguishes this species from the 

 others found in Japanese waters. It differs further from C. myriaster 

 by having a longer head and without white areas around sensory 

 pores and pits. It differs further from C. jordani by having two rows 

 of teeth in jaws, the origin of dorsal fin situated more anteriorly, and 

 ossification not bridging over sensory canal of the preorbital bone.
