serus Cope. It was found in a cave in the northern part of Bexar 

 County, Texas. The tooth belongs to the Scientific Society of San 

 Antonio. It was a far smaller tooth than that of figure 3, 



From the close resemblance existing between the carnassial found 

 at Vero and here referred to Leidy's Machairodus jioridanus and that 

 of Trucifelis fatalis found at Natchez, it is certain that both belong 

 to the same genus. For this genus the writer accepts at present the 

 name Trucifelis. We shaU have, therefore, the two species, Truci- 

 felis atrox and T. jioridanus. 



FELIS VERONIS, new species. 



Plate 28, figs. 5-7. 



When the author was at Vero, in October, 1917, he found along the 

 drainage canal, a short distance above the railroad bridge, in the bed 

 of sand known as No. 2, an upper left fourth premolar of a large tiger- 

 like animal. Views of this tooth are here presented (pi. 28, figs. 

 5-7). On comparing it with the corresponding teeth of the tiger 

 and of the jaguar {F. imraguensis, No. 4128 U. S. Nat. Mus.), and 

 with those of the machairodonts, it can not be doubted that its pos- 

 sessor belonged to a species of Felis. In order to facilitate comparison 

 the following measurements are presented, being those of the speci- 

 men in question, the same tooth of Felis tigris, and of the large South 

 American jaguar, Felis paraguensis HoUister.

Various differences between the fossil tooth and that of the tiger 

 appear other than those shown in the table of measurements. The 

 protocone of the Vero tooth is considerably less reduced than in the 

 tiger, its height and anteroposterior diameter being greater by one- 

 third. Immediately behind the protocone the width of the tooth 

 is reduced more suddenly than in the tiger; the preanterior tubercle 

 is much more prominent than that in the tiger; and the buttress 

 which descends from the principal cone to the protocone is sharp, 

 instead of rounded. In the jaguar the preanterior tubercle is missing 

 and the protocone is relatively more reduced than in the fossil. 

 The height of the main cusp is relatively greater than in either the
