38 FLORIDA GEOLOGICAL SURVEY-NINTH ANNUAL REPORT. 
TYTO PRATINCOLA (Barn Owl), Stratum 3. 
Plate I., Figs. 7 and 8. (Fig. 7 fossil). 
No. 6934. This is the distal moiety of a right tibiotarsus of an 
adult specimen of the Barn Owl ( Tyto pratincola) . It agrees, with 
surprising exactness, with the corresponding part of a tibiotarsus of 
this species of owl in a skeleton in the collection of bird skeletons 
in the Division of Birds, of the U. S. National Museum (No. 
19,636), with which I have compared it. 
LARUS ? (sp. ?), Stratum 3. 
(Plate I., Fig. 12.) 
No. 6773. In the lot at hand there are two fossil bones of birds 
bearing this number, one of whicii has already been described above 
(Fig. 5, PI. L), and the present one, which is the distal moiety of 
the right tarso-metatarsus of some water bird, and possibly, if not 
probably, of a gull (Lancs), or some form related to the gulls. It is 
about the size of the corresponding bone in the skeleton of an adult 
Larus atricilla; but its shaft is much broader above, and more com¬ 
pressed in the antero-posterior direction. It should be set aside 
until some material be discovered in the same locality, which may 
throw light upon it. 
ARDEA SELLARDSI, sp. nov., Stratum 3. • 
(Plate II., Fig. 15.) 
No. 7551. This is the distal third of a right tibiotarsus of a 
heron, somewhat smaller than Ardea herodias, and apparently dis¬ 
tinct from it. (3 +). It presents all the characters found in the 
same bone, or part of a bone, which we find in A. herodias, while 
at the same time its shaft is slightly stouter; the anterior tendinal 
groove narrower and more distinct; the anterior intercondylar val¬ 
ley narrower and deeper superiorly, and some minor differences. 
The condyles in the specimen are considerably abraded, and, more¬ 
over, broken off posteriorly. 
This fossil is the type bone of a new species of extinct heron, 
for which I propose the name of Ardea sellardsi, naming it for Dr. 
Elias Howard Sellards, in recognition of the valuable work he is
