PACIFIC SCIENCE, Vol. IX, October, 1955 
Ventral surface of snout with a median 
groove that contains teeth; caudal fin well 
developed; dorsal origin a little over a head 
length behind head (cf., Schultz, et al., 1953: 
71). 
I have dealt elsewhere (1950: 312-314; 
1952: 300-306) at some length with the rea- 
sons why Leptenchelys , Muraenichthys , and 
Schultzidia should be placed in the Ophich- 
thidae. 
Muraenichthys cookei Fowler 
12 specs., 103-173 mm., 1951. 
Posterior rim of orbit about over rictus; 
dorsal origin from 2 to 5 eye diameters ahead 
of anus; vomerine teeth uniserial (cf., Schultz, 
etal., 1953: 71, 72). 
These specimens are discussed in section 2. 
Muraenichthys gymnotus Bleeker 
3 specs., 52-118 mm., 1951. 
Dorsal fin originating about half a head 
length behind the anus; rear margin of eye 
slightly ahead of rictus; teeth on front of 
maxillary and dentary at least double-rowed; 
snout sharp, the distance from its tip to the 
rictus contained about 3.7 times in the head 
length (cf., Schultz, et al., 1953: 71-73). 
Muraenichthys schultzei Bleeker 
3 specs., 106-117 mm., 1951. Fowler and 
Ball, 1925, 12 specs. 
Dorsal origin about two-thirds of a head 
length behind anus; snout bluntly rounded; 
vomerine teeth two-rowed (cf., Schultz, et al., 
1953: 71-73).
