48 FLORIDA GEOLOGICAL SURVEY-NINTH ANNUAL REPORT. 
bral scute, in front, 39 mm. The nuchal scute area is not as narrow 
as it is in the. type and not as wide above (5mm.) as it is 011 the 
underside of the bone (6 mm.). The area of the first vertebral 
scute is marked by strong lines of growth. 
FARANCIA ABACURA (HOLBROOK). 
In the collection made by Dr. Sellards in stratum No. 3, at Vero, 
is the articular bone of a snake which seems to have belonged to 
this species. The bone has a length of 41 mm., but a small piece 
is broken from the front end. It has been compared with an artic¬ 
ular of a skull which belongs to Dr. R. W. Shufeldt, and which, as 
he reports, he took from a Farancia 6 feet and 3 inches long, found 
near New Orleans. This bone is 44 mm. long. Three other bones, 
considerably smaller, belonging to the National Museum, have been 
used for comparison. 
In the New Orleans specimen the two plates which enclose the 
insertion of the masseter muscle are of equal height, 7 mm. In all 
the other bones, including the fossil, the outer plate is much lower. 
In the fossil the inner plate is 8 mm. high. While the fossil presents 
some peculiarities, they are probably due to individual variation. 
The snake which possessed this bone was probably about 6 feet long. 
The lower jaw of Abastor is similar to that of Farancia, but the 
dentary extends backward only a short distance behind the front of 
the articular; while in Farancia the dentary, with teeth, is carried 
back more than half-way to the groove for the masseter muscle. 
TAYASSU LENIS (LEIDY). 
Plate 3- Figs. 2, 3. 
While at Vero, November 1, 1916, the writer found in the 
stratum of sand, No. 2, 460 feet west of the railroad bridge, a finely 
preserved upper left hindermost molar of a small peccary. An 
examination of this seems to show that it belongs to Tay assn lenis, 
originally described and figured by Leidy (Holmes Post-pliocene 
Foss. S. Car., p. 108, pi. XVII, figs. 13, 14) as Dicotyles fossilis. 
In 1869 (Ext. Mamm. N. A. p. 389) Leidy narrie.d this D. lenis. It 
is now referred to the genus Tayassu. 
The length of the crown of the molar (pi. 3, fig. 2) found at 
Vero is 14.8 mm.; the width in front is 10.2 mm. The tooth is
