tapering rapidly, becoming very slender toward tip, much as in Uroconger lepturus ; 
head notably large, occipital region elevated; snout long, 1.5. times eye, 3.75 in 
head, projecting beyond lower jaw a distance equal to two-thirds of eye; eye 5.3 in 
head ; anterior and posterior nostrils with low raised flaps; cleft of mouth reaching 
to middle of eye; teeth in jaws all pointed, closely set.in broad bands in both jaws; 
vomerine patch subtriangular, rounded anteriorly ; a few scattered, pointed teeth 
slightly longer than the rest in the front portion; the posterior (vomerine) teeth 
short and blunt; circular part of patch of teeth on vomer exposed when mouth is 
closed ; tongue free ; pectoral 3.3 in head; dorsal beginning over gill-opening, dis- 
tinetly in front (one-half width of pupil) of pectoral ; thirty-one pores before vent, 
Color in spirits light olive brown, paler below; top and sides of head more 
heavily punctulated with dusky ; dorsal and anal black edged, the whole of both 
fins tending to blackish on last third or half of tail ; pectorals plain; tip of tail 
black. 
Described from two excellent specimens eighteen and nineteen inches long 
from Takao. 
This species seems to bridge the rather slight distinction heretofore made 
between Leptocephalus and Congrellus, having the long tail of the former and the 
anteriorly inserted dorsal of the latter. 
We may note that Myrophis (Gnathophis) heterognathus (Bleeker) seems to be a 
young specimen of Leptocephalus nystromi Jordan and Fowler, both species being 
described from Nagasaki. The species should stand as Leptocephalus heterognathus. 
Family OPHICHTHYIDZ. 
61. Ophichthus evermanni sp. nov. (Plate LXVII, upper figure.) 
Two specimens from Takao, seventeen and twenty-one inches long, seem to 
agree fairly well with the “variety” Ophichthus cephalozona recorded by Dr: 
Giinther from Japan (Catalog of Fishes in the British Museum, Vol. WANE 9). TOY, 
having the body very distinctly marked with numerous blotches resembling cross- 
bands. The nuchal band is scarcely less distinct than in the figure by Dr. Bleeker. 
The dorsal of one specimen shows no distinct white edge, while in the other (nine- 
teen inches long) the white margin shows plainly. In both specimens the dorsal 
partakes more or less of the mottled coloration of the body. The pectoral is 34 or 
4 in head; the dorsal begins in front of the posterior fourth of the reflexed pectoral. 
This species is recorded as Ophichthus cephalozona from Hokoto, by Jordan & 
Evermann.
