VERTEBRATES FROM MIOCENE, PLIOCENE AND PLEISTOCENE. IO~ 
cality is described and the mammalian species listed in the subse¬ 
quent pages of this volume in connection with an account of fos¬ 
sil human remains. Although more species are represented the 
fauna at this locality is essentially that which has already- been 
listed as characteristic of the Pleistocene of Florida. 
DESCRIPTION OF A NEW DOLPHIN. 
Plate 14. 
Through the courtesy of Professor John F. Baerecke, 
the writer has been permitted to include in this paper a description 
of an excellently preserved skull of the dolphin, GlobiccpJiahts. 
This skull, which represents apparently a new species, was found 
while excavating for the foundation of the Codrington Building 
in DeLand. It was imbedded in sand at a depth of about 10 feet, 
according to the statement of Professor Baerecke, who was pres¬ 
ent at the time the skull was taken from the ground. 
Pliocene and Miocene shell marls underlie the city of DeLand. 
This skull, however, comes from the sands above these marls, and 
while the skull may be of Pliocene age, it seems more probable that 
it belongs to the Pleistocene, especially as the bones are but slight¬ 
ly mineralized, and on the whole have the appearance of being very 
recent. Furthermore the species is rather closely related to the 
living species of the genus. In addition it may be noted that at 
Orange City Station, a few miles west of DeLand, shell marls are 
found which are regarded as probably of Pleistocene age.* More¬ 
over, in the marl pits at DeLand an unconformity is found at the top 
of the Pliocene shell marl, this break very possibly representing the 
dividing line between the Pliocene and the Pleistocene. 
Globiccphalus bciereckeii sp. nov .—The characters which dis¬ 
tinguish this species from the modern forms are best seen at the 
base of the skull, where the articular condyles are larger and stand 
more nearly vertical than those of the recent species. The fora¬ 
men of the skull is likewise more nearly oval than that of the mod¬ 
ern species. The transverse measurement of the foramen is 66 
mm.; vertical, 55 mm. The total length of the skull is 57 cm.; 
length of rostrum to the maxillary notch, 28 cm,; width of rostrum 
at base, 22.5 cm. The sockets for seven teeth are seen in the 
jaw, and there may have been two or three more teeth as the tip
