Lophocoelus Ameghino 
Lophocoelus Amegh., 1904, Anal. Soc. Cient., Rep. Argen., t. 58, p. 245. 
Lophocoelus Amegh., 1904, Anal. Mus. Nac., ser. 3, t. 3, p. 352. 
The genus is founded on a single upper third molar from 
Mazaredo, which is distinguished by a feeble style on the 
external face, by the anterior lobe being obliquely placed, 
and by the presence of a small secondary bay on the 
posterior side of the great internal basin. 
L. macrostomus Amegh., loc. cit. above. 
This species is the only one described, and has the 
generic features, the upper m. 3 being 21 mm. long, by 25 
mm. wide. 
Henricofilholia Ameghino 
Henricofilholia Amegh., 1901, Bol. Acad. Nac. Cordoba, t. 16, p. 404. 
The type species is /7. cingulata, based on a single upper 
molar. In general the upper molars are similar to those 
of Leontinia, but more brachydont, and with the internal 
cingulum well developed and tending to be crenulated. 
Four species have been made, all based on isolated upper 
molars.

This is based on an upper molar 1 of which I reproduce 
Ameghino’s figure. It measures 28 mm. long by 29 mm. 
wide.
