So far as known, no squalodont skull possesses a small canal, open- 
ing near the center of the concave horizontal plate of the maxilla 
and approximately in line with the posterior margins of the nasal 
passages, which connects with the infraorbital system. Such a canal 
is present on the right edge of the fragment and is plainly indicated 
in Leidy’s figure. Canals in a corresponding position are to be found 
in crania belonging to Yale University and obtained from the same 
deposits.

St.-Petersbourg, ser. 7, vol. 20, No. 1, p. 330, 1873. 
Type specimen.—Consists of a fragment of the mandible with three 
teeth in situ. Type in Cambridge University Museum, England. 
Type locality.—The tufa of Malta.> Burdigalian or Lower Miocene. 
Subsequent allocation.—This interesting specimen has been the sub- 
ject of much controversy, and at various times has been placed with 
the pinnipeds, squalodonts, and zeuglodonts. Miiller® came to the 
conclusion that it represented a zeuglodont, for he says: ‘‘ Ueber die 
generische Identitait des Zeuglodon und der Zihne bei Scilla, hegte 
ich Keinen Zweifel.”’

7, vol. 20, No. 1, pp. 316-318, 1873; vol. 21, No. 6, pp. 29-30, 54, pl. 4, figs. 
18-19 [outline drawings of molars], 1874 [based upon the following: Arionius 
servatus Meyer’ and ‘‘ Viertes Cetaceum der Molasse’’ of Jiger®]. 
Type specimen.—A poorly preserved rostral fragment obtained 
from Professor Schiibler formed the basis of Jager’s remarks. Another 
incomplete skull became the type of Arionius servatus Meyer. Brandt, 
apparently, made this last-mentioned specimen the type of his Squa-
