form of this element is very characteristic among the Talpide, the spe- 
cies may be determined from it with considerable precision. Its form 
is less stout than in Talpa europea and Scalops aquaticus, but consider- 
ably more so than in Condylura cristata. In the uncertainty as to 
whether it can belong to Scalops brewert, I leave it without a name. 
? VESPERTILIO, Linn. 
Numerous slender bones referable to this or an allied genus, are found 
in the cave deposit. 
Mastropon, Cuyv. 
MASTODON AMERICANUS, Cuv. 
Numerous fragments of teeth, cranium, vertebre, and extremities, of a 
large individual, with tusks measuring five to six inches in diameter. 
Some three-crested, and several primary or two-crested molars, indicate 
a second, smaller animal. 
Tapirus, Briss. 
TAPIRUS AMERICANUS, Auct. 
Numerous teeth from all positions in both jaws indicate several indi- 
viduals of different sizes. Some of them are of the size of the existing 
species of South America, and do not exhibit any differences of specific 
importance.

Holmes’ Postplioc. Foss. 8. Ca., Pl. xvii. figs. 4, 5, 7, 8. 
Four superior and six inferior moiars do not differ in any respect from 
those of the preceding species. excepting in size. In this they exceed the 
latter, having about twice the superficial area. Leidy appears to have 
proposed this species on account of size only, and the specimens may in- 
dicate a valid species. Two superior molars, perhaps referable to the 
T. americanus, differ less in size, exceeding a little those of our recent 
specimens. 
Dimensions of three superior molars of the largest (Z. haysti), medium 
and smallest (7. americanus) size are given. Thelast two are worn, the 
first had not protruded through the gum.

In addition to the teeth, there are numerous bones of the extremities,

Equus, Linn. 
Numerous phalanges of two species of slender proportions and smaller 
Size than the recent domesticated horse. Neither the species nor genus 
are determinable as yet, from the remains.
