688 INDEX GENERUM MAMMALIUM. 
Tribonophorus Burnert, 1829. Chiroptera, Pteropodidze. 
Quart. Journ. Sci., Lit. & Art, XXVII, 269, Apr.-June, 1829—nomen nudum? 
Type: Tribonophorus desmarestii Burnett, from India? 
* Tribonophorus desmarestii, Mantled R.'[oussette], as here used is a nomen 
nudum, but seems to be merely a new name for Pferopus palliatus Geoffroy.* 
In Griffith's Cuvier, Animal Kingdom ( V, 58-59, 1827), which was evidently 
used by Burnett in preparing his table, the same common name is given for 7. 
palliatus with the remark, ‘‘This species, says Desmarest, when better known, 
will probably form a new genus, intermediate between Pteropus and Cephalotes.”’ 
Tribonophorus: rpíficov, a threadbare cloak; @opos, bearing—in allusion to the 
color.

Species, 4: Zricentes crassicollidens Cope (type), T. inxquidens Cope, Mioclenus 
subtrigonus Cope, and M. bucculentus Cope, from the Eocene of New Mexico. 
Extinct. 
Tricentes: rpi-, three; Kevté@,.to prick—in allusion to the three premolars.

Trichecus Oken, Lehrbuch Naturgesch., 3ter Theil, 2te Abth., 685-690, 1816. 
Type: Trichechus manatus Linneeus, from the Atlantic coast of tropical America. 
Trichechus: This name originated with Artedi, who gave the following derivation 
in his Iehthyologia, pars 1, p. 74, 1738: ‘ Trichechus, a 6pt&, crinis, and Zy0Us, 
piscis, quia solus inter pisces fere hirsutus sit." (Allen’s Pinnipeds, p. 15.) 
Billberg (in allusion to the walrus) suggests the following etymology: Trichzcus: 
Tpiyaikos, qui versatur in preeliis. 
The Century Dictionary gives the derivation as 697, rpiyos, hair; &yc, to have.

Species: Trichechus rosmarus Linnzeus, from the Arctic Ocean; and 7. manatus 
Linn:eus, from the Atlantic coast of tropical America. Although Trichechus 
has been very generally applied to the walrus, it is not available for this group, 
since Linn:eus, in 1758, applied the same name to the manatee. It is more- 
over antedated by Odobenus Brisson, 1762.
