anv. 16, TWO SQUALODONTS FROM MARYLAND—KELLOGG. 13 
Neosqualodon and Microzeuglodon possess the same peculiar type of 
dentition and, in want of additional material, may be placed tenta- 
tively in the same limited group. 
DELPHINODON? DEBILIS (Leidy). 
Phoca debilis Letpy, J., Proc. Acad. Nat. Sci. Philadelphia, vol. 8, p. 265, 1856; 
Journ. Acad. Nat. Sci. Philadelphia, ser. 2, vol. 7, p. 415, pl. 28, figs. 12, 13, 
1869. 
Type specimen.—Original description was based on three molar 
teeth, but one was withdrawn in 1869 and made the type of Phoca 
modesta. Types, Nos. 10324-10325, are in the Academy of Natural 
Sciences of Philadelphia. 
Type locality —Sands of Ashley River, South Carolina. Edisto 
marl or Upper Miocene. 
Subsequent allocation.—This species was placed in the genus Squa- 
lodon by Cope.* The teeth as figured by Leidy do not bear any 
resemblance to the teeth of squalodonts, and they do not agree sufii- 
ciently with those of Delphinodon to be definitely referred to that 
genus. Even with allowance for variation, it seems probable to the 
writer that they represent some Miocene delphinid, as they are not 
suggestive of any known squalodont. 
PATRIOCETUS DENGGI Abel. 
Cetotheriopsis linziana Branvt, J. F., Mem. Acad. Imp. Sci. de St.-Petersbourg, 
ser. 7, vol. 20, No.1, pp. 42, 43-44, pl. 18, figs. 5b, 5c, 5d, 6b, 6c, 6d, 9b, 10c, 11d 
(lumbar vertebrae); pl. 18, figs. 5e, 5f, 5g, 6e, 6/, 6g (caudal vertebrae), 1873. 
Patriocetus denggi ABEL, O., Denkschr. Kais. Akad. Wiss. math.-naturw. KI]. 
Wien, vol. 90, pp. 160, 194-199, text fig. 13, 1913. 
Type specimen.—Based upon three lumbar and three caudal verte- 
brae. Types in the Museum Francisco-Carolinum at Linz, Austria. 
Type locality—Marine sand in the vicinity of Linz, in the valley of 
the Danube River, upper Austria. Upper Aquitanian or Upper Oli- 
gocene. 
Subsequent allocation.—Although Abel tentatively proposes a new 
specific name for these vertebrae, he remarks that they may belong 
possibly to Patriocetus ehrlicht [= Patriocetus grateloupii]. In view 
of the number of types of cetacean skulls that are known from these 
marine sands, any allocation of isolated vertebrae will be subject to 
dispute.

Squalodon ehrlichii VAN BENEDEN, P. J., Mém. Acad. Roy. Sci. Belgique, Bru-

Type specumen.—In his original description Van Beneden associated 
two distinct cetaceans under this name. His material included a
