714 INDEX GENERUM MAMMALIUM. 
Zebu ? 1845. Ungulata, Artiodactyla, Bovidz. 
London Encyclopedia, X XII, 752, 1845 (art. Zoology ). 
Zebus BrvrH, Journ. Asiatic Soc., Bengal, X XIX, No. 1, 283, 1860; Cat. Mamm. 
Mus. Asiatic Soc., 159, 1863. 
The genus was first described in an unsigned article in the London Encyclope- 
dia and was evidently based on Bos indicus, although no species was men- 
tioned. Blyth's genus was based on **the Zebu or humped cattle of the hotter 
regions of Asia and Africa." 
Zebu: French zébu, a name adopted by Buffon and supposed by him to be from 
an African word. If not invented, it is probably intended to represent the 
fast Indian zobo, the name of a breed of cattle supposed to be a hybrid 
between the zebu and yak. (Century Diet.) 
The origin of the name ze» is quite unknown, it being foreign to all the native 
languages of India.  (LvpEKKER, Wild Oxen, Sheep, and Goats of All Lands, 
20, 1898.) 
Zebua (‘ERXLEBEN’) GRAY, 1837. Marsupialia, Macropodid:e. 
Charlesworth's Mag. Nat. Hist., I, 582, 1837. 
Possibly a misprint for Yerboa Zimmermann, 1777. Gray gives the name only 
in the form ‘‘ Macropus major Shaw. Zebua gigantea Erxl." Erxleben used the 
name Jaculus gigantea, but Zimmermann in the same year (1777) used the 
term Yerboa gigantea for the same species.

Soc., 159, 1863. 
Based on ‘the zebu or humped cattle of the hotter regions of Asia and Africa.’

Zugodon ScuppER, Nomenclator Zool., pt. 1, 557, 1882. 
New name for Basilosaurus Harlan, 1824, supposed by the describer to have been 
a genus of saurians. Owen having demonstrated the Mammalian nature of 
the teeth on which the genus was based, **in compliance with the suggestion 
of Dr. Harlan, . . . proposes to substitute for the name Basilosaurus tbat of 
Zeuglodon, suggested by the form of the posterior molars, which resemble two 
teeth tied or yoked together." 
Extinct. 
Zeuglodon: $e£6y An, the strap or loop of a yoke; d5@v=d6ovs, tooth.
