relationship they may have to the other described forms. It is doubt- 
ful whether these specimens can be identified until more complete 
remains are found. 
SQUALODON LINZIANUS Brandt. 
Squalodon linzianus Branvt, J. F., Bull. Acad. Imp. Sci. de St.-Petersbourg, 
vol. 16, p. 566, October, 1871; Bull. Acad. Imp. Sci. de St.-Petersbourg, Me- 
langes Biol., vol. 8, p. 196, 1871; Mém. Acad. Imp. Sci. de St.-Petersbourg, 
ser. 7, vol. 20, No. 1, p. 47, 1873. 
Type specimen.—Based upon a tympanic. Type 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 
Oligocene. 
Subsequent allocation.—Brandt’s explanations are not always easily 
understood, for under his discussion of Cetotheriopsis he states that 
this tympanic may perhaps belong to Squalodon linzianus,* though 
further on he clearly states that it is referable to Squalodon ehrlichii.” 
Abel® refers this tympanic to his Patriocetus ehrlichi [=Patriocetus 
grateloupir (Meyer)]. 
CETOTHERIOPSIS LINTIANUS (Meyer). 
Balaenodon lintianus Meyrr, H. Von, Neues Jahrbuch fiir Mineralogie, Stuttgart, 
p. 550, 1849. 
Stenodon lentianus VAN BENEDEN,®P. J.. Mém. Acad. Roy. Sci. Belgique, 
Bruxelles, vol. 35, pp. 73-79, pl. 4, and text figs. 2, 1865. 
Type specimen.—The original description was based upon a pos- 
terior cranial fragment, an atlas and another large vertebra, a tym- 
panic and a caniniform tooth. Von Meyer thought this tooth bore 
some resemblance to Balaenodon of Owen, and hence referred all of 
his material to that genus. The specimens are in the Museum Fran- 
cisco-Carolinum at Linz, Austria. | 
Type locality.—Tertiary sands in the vicinity of Linz, in the valley 
of the Danube River, upper Austria. , Upper Aquitanian or Upper 
Oligocene. 
Subsequent allocation.—The year following the publication of the 
original description of Balaenodon lintianus, Meyer® apparently 
reconsidered his previously published statements and concluded he 
could not say positively that the tympanic and the tooth belonged 
to the genus Balaenodon. He also asserted that the cranial fragment 
showed more similarity to Zeuglodon than to Squalodon. The genus 
Stenodon of Van Beneden, like Balaenodon lintianus Meyer, was based 
upon a composite lot of specimens belonging to one or more unre- 
lated cetaceans. The cranial fragment together with additional 
skeletal material formed the basis for the Cetotheriopsis linziana of
