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 //. 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 I of which I reproduce 

 Ameghino's figure. It measures 28 mm. long by 29 mm. 

 wide.
