together by 1.28 to 1.37 times the length of head, or 28.3 to 

 31.5 per cent of its own length; dorsal begins exactly over anus 

 in my specimens, though usually it is inserted a little before 

 vent and anal begins a very short distance behind it. 



Upper jaw has a continuous many-rowed band of small teeth, 

 which tapers posteriorly and unites anteriorly with the vome- 

 rine teeth without a delimiting groove at junction; teeth on 

 vomer in an elongate paddle- or pear-shaped band which extends 

 as far back as do the maxillary bands; bands of teeth in 

 lower jaw broadest anteriorly, tapering posteriorly; they are 

 almost separated at the symphysis by a distinct groove, being 

 united and continuous only at the extreme anterior portion. 



Specimens in alcohol uniform dark brown above, merging into 

 very pale brown beneath; anal pale or light yellowish except 

 near tip of tail where it is dark ; in life all the fins were evidently 

 uniform in coloration with back and sides. 



Here described from two specimens, 515 and 600 millimeters 

 in length, collected by Mr. Ale jo Arce at Lake Bato, Camarines. 

 There are two stuffed specimens, collected at Cavite, in the 

 museum of the University of Santo Tomas. There is also a 

 specimen, 320 millimeters long, from Guam in the Bureau of 

 Science collection. This specimen has the eye contained but 

 7| times in the head, and is quite different in several respects 

 though it undoubtedly belongs here. The undersurface and all 

 except the posterior fifth of the anal are clear uniform pale 



yeiiowisn. . 



This eel reaches a length of 1 meter and occurs from Natal 

 and the east coast of Africa to the coasts of India the East 

 Indies, Tasmania, New Zealand, and the islands of the South 

 Pacific.
