I48 FLORIDA GEOLOGICAL SURVEY-EIGHTH ANNUAL REPORT. 
maining species, Psertdemys floridana persimilis, is regarded, by 
Hay as a variety of the modern Pseudemys floridana. A nearly 
complete carapace of the extinct species, Terrapcnc innoxia, was 
found in this horizon. 
Bird bones, although by no means numerous, are found in 
greater diversity than in stratum No. 2, and more than one species 
is repreesnted. The large extinct bird, Jabiru ? zveillsi, which 
characterizes stratum No. 2, has not been found in this horizon. 
Mammals in stratum No. 2 as in the older horizon are numer¬ 
ous. The species recognized are given in the list on page 158. All 
of those mentioned in this list were found, in place and in associa¬ 
tion with human remains, flint and bone implements. 
NOTES OX MAMMALS INCLUDING DESCRIPTION OF A NEW CANID 
DIDELPHIS. 
An cppossum is represented in the collection from both strata 
2 and 3 of the section by parts of the lower jaw and by detached 
teeth. The material that has been obtained apparently affords no 
characters upon which the species may be separated from the mod¬ 
ern Didclpliis virginiana. 
MEGALONYX. 
PI. 25, fig. 2; pi. 30, fig. 6. * 
The sloth. Megalonyx jeffersonii, is represented by a part of 
the lower jaw, a right upper canine tooth, molar tooth, hyoid bone, 
axis, astragalus, first median phalanx and the claw of a lateral 
digit. Of these bones the hyoid bone, fig. 2, pi. 25 was obtained 
in association with the first human remains found at \ ero in stra¬ 
tum No. 2 on the south bank 331 feet west of the bridge. 
CHLAMYTHERIUM. 
PI. 28, figs. 4-6; pi. 30, fig. 7. 
The armadillo-like edentate, Chlamytlicriuui scptcntrionalis, is 
found in both strata 2 and 3 of the section and is represented by a 
right lower jaw, part of a left lower jaw, a foot bone and numer¬ 
ous dermal scutes. The dermal scutes and foot bone were found 
in stratum No. 2 near the human remains. 
DASYPUS. 
PI. 29, figs. 1-2. 
The armadillo, Dasypus, is found in both strata 2 and 3 and is 
represented by dermal plates. This armadillo is found also in the 
Pleistocene cave deposits at Ocala, Florida.
