NO. 1239. APODAL FISHES OF JAPAN— JORDAX AND SNYDER. 851 



the maxillary is 3 in head; head and trunk 1| in tail; dorsal and anal 

 pale at base, with hroad black niarg-in; lateral line with the pores pale, 

 the line itself a pale streak; dorsal inserted over tip of pectoral. We 

 have found in Japan no Conger corresponding to the Atlantic species, 

 thoug-h this one conies nearest it. {e'pe/Sevvos^ very l)lack — as Erebus.) 

 We refer with some doubt to this species, a small eel, 5 inches long, 

 f rom Wakanoura. Head If in trunk; head and trunk If in tail; maxil- 

 lary extending to posterior border of eye, 2^ in head; snout 8f in head; 

 lower jaw not nuich shorter; pectoral 2^ in head; dorsal inserted over 

 posterior third of pectoral; 42 pores before vent; lateral line forming 

 a continuous streak. Coloi- light olive; pores of lateral line large, 

 pale, but without white dots; sides with some })lack dots; dorsal with 

 the black margin obsolete except posteriorly w^here it is narrow; anal 

 showing traces of a dark edge posteriorly; tip of tail white; pectorals 

 pale; pores on top of head not evident. 



g. LEPTOCEPHALUS KIUSIUANUS Jordan and Snyder, new species. 



kur(>ana(t<) (bla(;iv conger). 



Head 1^ in trunk; head and trunk H hi tail; lower jaw rather short; 

 snout shortish, li in head; eye If in snout; cleft of mouth moderate, 

 the maxillary 3 in head, extending to posterior margin of eye; pec- 

 toral pointed, 3i in head; dorsal inserted over end of second third of 

 pectoral; insertion of dorsal to gill opening, 4^ in head; dorsal and 

 anal rather high. 



Color dark brown, the dorsal and anal 1>roadly edged with black; tip 

 of tail with a slight white margin. Pectoral dusky, w^tli a pale edge. 

 Lateral line conspicuous, with small pale pores, 38 before vent; no 

 white spots anywhere. Pores on head inconspicuous. 



One specimen, type No. 6467, Leland Stanford Junior University 

 Museum, 2^ feet long, from Hakata, province of Chikuzen, in Kiusiu. 

 It differs strongly from any other species we have seen in the relative 

 shortness of the trunk. The dorsal is inserted anteriorh^, but not so 

 far forward as in Z. nystro//tl, which has also the trunk short. Lepto- 

 ceijliakm marginatum {=n<)ordzickl^ Bleeker) from Polynesia, has higher 

 tins and slenderer body. 



lo. LEPTOCEPHALUS JAPONICUS ' Bleeker. 



Conner jajyo»*"('M6' Bleekek, Enum. Espeoe Ic. Poiss. Japon, 1874, p. 82, Japan. 



This species, according to Bleeker, is characterized b}^ its dentition, 

 its convex anterior profile, by the relative length of its head and trunk, 



1 LEPTOCEPHALUS HETEROGNATHUS (Bleeker.) 



Closely allied to this genus is a young Conger in very bad condition received by 

 Dr. Bleeker from Nagasaki. According to Giinther, the typical example belongs 

 to Congermuriena and is very closely allied to the New Zealand sjjecies, C. habcnata, 

 having a similar dentition ( like that of Comjrellus, except that the teeth are blunt) .
