286 NEW GENERA AND SPECIES OF FISHES, 



Differs from the two preceding species in the much larger head 

 and at the same time much slighter projection of the upper jaw 

 beyond the lower. It is more closely allied to G. loyigicauda than 

 to C. hcbbenata. 



4. CoNGBRMURiENA HETEROGNATHA. 



= Myrophis heterogaathis, Bleeker, Act. Soc. Sc. N^erl. 

 Ind. V. p. 9, pi. iii. f. 1. 

 Hab. — Japan. 



5. CONGERMUR^NA NEOGUINAICA. 



= Conger neoguinaicus, Bleeker, Act. Soc. Sc. N^erl. Ind. 



vi. p. 22. 



Hab. — Dorey, New Guinea. 



Pr. Giinther's suggestion that this species " may be identical 



with C. hahenata " cannot be accepted if Bleeker is correct in 



describing the jaws as of equal length, the snout as 4^ in the 



length of the head, and the vomerine teeth as biserial and 



" bluntly conical "; indeed, in view of the latter character, I am 



not fully satisfied that the species properly belongs to the present 



group.

 Eyes large. Dorsal originating above or nearly above the base 

 •of the pectorals, which are well developed. Vent usually but 

 little in advance of the middle of the length. (A little conger; 

 diminutive of Congrus, a related genus, = Leptoceplialus).
