Cycleptus elongatus (Le Sueur). 



One adult from St. Louis, IVIissouri, and another from Kiskiminitas 

 River, Pennsylvania. 



Genua AMBLODON Rafinesque. 



This name is allowed to supersede Idiohus Rafinesque, now largely 

 in use. Amblodon is based on two species, Amhlodon buhalus Rafin- 

 esque and Amblodon niger Rafinesque. Jordan and Gilbert have 

 designated Amblodon bubcdus Rafinesque ( = in part Aplodinotus grun- 

 niens Rafinesque) as the type,^ and thus Amblodon would become 

 a synonym of Aplodinotus according to their ruling. However, 

 as Amblodon bubcdus Rafinesque, the type species of Amblodon 

 Rafinesque, applies primarily to the small-mouthed buffalo, I 

 cannot accept their contention. 



MEGASTOMATOBUS subgen. nov. 

 Type Sckrognathus cyprinella Valenciennes. 

 Mouth large, oblique, terminal, and upper lip about level with 

 lower edge of eye. Lips thin, nearlj^ smooth. Pharyngeals weak. 



This name is proposed for the large-mouthed buffaloes as Sckrog- 

 nathus Valenciennes, usually attributed to them, has Catostoinus 

 cijprinus Le Sueur (its first species) designated as the type by Jordan 

 and Gilbert,- and is thus a synonym of Carpiodes Rafinesque. 

 (.'^£/'«, large; <TT<i/j.a^ mouth; /5'"j9, buffalo.) 



Amblodon cyprinella (Valenciennes). 



Four from Leavenworth. Kansas; four from Wheatland, Iowa. 



Amblodon bubalus Rafinesque. 



One from Blue River, Indiana; three from near Leavenworth, 

 Kansas; two from ''Western United States"; three without data.
