 because it has no canines. Though its inner enlarged mandibular teeth 

 are smaller and less cauinirorni than in the typical species of Gobiodon, 

 thev are nevei'theless similar in both structure and position, and we do not 

 regard them as sufficiently characteristic to justify the maintenance of 

 the genus. EUeri/a, Castelnau, is iuaccui-ately and superficially defined, 

 but is evidently based upon a species of Gohiudoit (see notes under 

 (7. vertical is).
