of mouth 2.75 in head, the maxillary extending a distance behind orbit 

 equal to length of snout; eye 18 in head; dorsal origin almost exactly 

 midway between vent and gill opening, the fin very low anteriorly; tail 

 tapered to a sharp point, tipped with short caudal fin continuous with 

 dorsal and anal; no pectorals; gill openings a distance behind eye equal 

 to 2.25 times length of maxillary; vomerine teeth in two rows; teeth in 

 jaws uniserial. Color in spirits light brownish, everywhere finely specked 

 with darker, except on belly, which is pale. 



This species is known to us from a single specimen, 3.75 inches long, 

 collected in Manila Bay by Dr. J. C. Thompson, of the United States 





The type 



In its large mouth and in many other features this eel resembles 

 Muramichthys macrostomus Bleeker, but the insertion of the dorsal is 

 different. 



In the description cited above the statement "depth equal to 

 distance from tip of snout to back of orbit" is evidently an error, 

 since the figure shows the ratio to be altogether different. I have 

 not been able to recognize this species among the specimens of 

 Murssnichthys at my disposal.

Depth 8H to 5% in head and 21.5 to 39 in length; head 1_75

 eye from two-thirds to three-fourths the length of snout and 11
