VERTEBRATA AT VERO.

remarkable for its simplicity of construction. Besides the four 
principal cones there is a heel consisting of two minute tubercles. 
No other tubercles appear anywhere. A faintly developed ridge 
descends from the summit of the metacone and meets a similar 
hardly perceptible ridge which descends from the summit of the 
protocone. There is no cingulum. A slight ridge descends from 
the paracone to the front of the base of the protocone. 
Mr. I. M. Weills, of Vero, sent the writer a small collection of 
fossils which were found along the drainage canal at Vero. Among 
these was a remarkably small upper left canine (pi. 3, fig. 3) of a 
peccary. This also the writer refers to T. lenis. It was found 
near the top of No. 2. The front border is worn away from whet¬ 
ting against the lower canine. Its original height cannot be deter¬ 
mined. Root and crown together now are 26 mm. high; the crown 
itself, 14 mm. The fore and aft diameter of the base of the crown 
is 7.2 mm.; the thickness, 5.2 mm. On the abraded surface the 
pulp cavity is exposed. A second upper left canine, from stratum 
No. 3, catalogue No. 6944, is much less worn on the front edge. 
The root and crown together measure 32 mm.; the crown above, 
13 mm. The fore-and-aft diameter at the base of the. crown is 
7 mm. The thickness is 5 mm. These teeth are very small when 
compared with those of the existing pecaries. 
On the page just cited of the Extinct Mammalia, Leidy referred 
to a remarkably small canine tooth of a peccary which Cope had 
originally described as Cynorca proterva. This canine had a .fore- 
and-aft diameter of 9.4 mm. and a thickness of a little more than 
6 mm. It thus resembled the canine found at Vero. 
One of the two teeth of Tayassu lenis originally figured by 
Leidy was a lower molar, probably a second. It measured 7 by 
5.75 lines; that is 14.6 mm. by 12 mm. In two existing peccaries 
measured the length of the second lower molar is almost exactly 
that of the uppermost hinder molar. In one of them the width of 
the second lower molar is somewhat less than that of the upper 
hindermost; in the other it is greater. It is seen from the above 
measurements that the length of the Vero tooth is almost the same 
as that of the second lower molar described by Leidy. The width 
of the Vero last molar is less than in Leidy’s second molar. The 
lower hindermost molar which Leidy described had a length of 
about 17 mm.
