to middle of eye, anterior ones tubulate, close to the tip of the 

 snout. Mouth wide, ending below posterior part of the eye or 

 not so far. Lips rather thin or greatly developed. Teeth acute, 

 in jaws in bands or in a few series, gaining in size posteriorly, 

 not so closely set as in Conger and not forming a cutting edge. 

 These series are increasing anteriorly into a band. On the 

 vomer a short patch of larger teeth or a patch of small teeth,

Key to the indo-australian species of Congrellus. 



1. Teeth on the intermaxillary plate enlarged, in a patch 



situated outside the mouth (Bathycongrus Ogilby) . . C. roosendaali p. 261.

situated inside the mouth (Congrellus Ogilby) . . . . C. anago p. 262.

 maxillary plate extending forwards beyond the mandibles and lying outside the 

 mouth as Bathycongrus Ogilby.
