The cleft of the mouth extends to, or nearly to, and in old examples 

 behind, the hind margin of the eye, which is small. Tail consider- 

 ably longer than the body. The band of mandibiilary teeth divided 

 by a longitudinal groove. Brown mottled with black, or uniform 

 blackish.

I have long hesitated to unite the Murcena manillensis of Blocker 

 with this species ; but after having examined all our examples, I 

 came to the conclusion that the relative position of the eye and 

 angle of the mouth is evidently subject to some variation in this 

 species ; and especially an example from the Philippine Islands, 

 which in all other respects agrees most closely with M. manillensis, 

 has the mouth cleft at least to below the hind margin of the eye. 

 The principal character by which this species may be recognized is 

 the advanced position of the dorsal fin.

The length of the head is nearly equal to the distance of the gill- 

 opening fr^om the origin of the dorsal fin, or one-half of that from 

 the origin of the anal fin. Lips broad and fleshy. The cleft of the 

 mouth extends scarcely behind the eye, which is small. Tail con- 

 siderably longer than the body. Mandibulary teeth divided into 

 two strips by a longitudinal groove.

3. Anguilla fidjiensis. 



The length of the head is more than the distance of the gill- 

 opening from the origin of the dorsal fin, and more than one-half of 

 that from the origin of the anal fin, equal to the distance between 

 the origins of the dorsal and anal fins. Lips broad and fleshy. The 

 cleft of the mouth extends to below the hind margin of the eye,
