The name Triclieclius^ for so long a time in general use ibr 

 the AValruses, proves not, as long ago shown by Wiegmann,* von 

 Baer, Miiller, Stannins, and later by other writers, to belong at 

 all to these animals, but to the Manatee. The name Triclieclms 

 originated with Artedi in 1738, in a x)osthnmous work f edited 

 by Linne. The characters given were ^^ Denies i^lani in ntraque^ 

 maxilla. Dorsum imi)enne. Fistula . . . . " The cita- 

 tions under Tricliechus embrace no allusion to the Wakus, but 

 relate wholly to Sirenians, or to the Manatee, as the latter was 

 then known.| Artedi's description of the Manatee is quite full 

 and explicit, but includes also characters and references belong- 

 ing to the Dugong. Trichechtis forms Artedi's " genus LI," 

 and is placed in his "order V, PlayiurV (embracing the Ceta- 

 ceans and Sn-enians, the other genera of this order being Phy- 

 seter, Delj)Mnus, Balcena, 3Io)wdon, and Catodon), and is hence 



'^ Respecting the jiroper generic name of the Walruses, Wiegmann, in 1838, 

 thus forcibly expressed his views : ' ' Die Gattung Odohemis [von Brisson,1756] 

 hiitte beibehalten werdcu miissen, da der ganz abgeschmackte Name Triche- 

 cJius gar nicht dem Walrosse, sondern iirspriinglich dem Mauati angehort, und 

 von Artedi fiir diesen gebildet war, nm die bei einem Fische oder vielmehr 

 Wallfische auftallende Behaarung zu bezeichnen." Archiv fiir Natnrge- 

 schichte, v. Jahrg., Band i, 1838, p. 116. 



t Ichthyologia, 1738, pars i, p. 74; pars iii, p. 79; pars iv, p. 109. In Arte- 

 di's work the name is twice written Trichechtis and twice Thrichechus. On j). 

 74 of pars i, where it first occurs, its derivation is given, uamely : " Triclw- 

 dius a &pi^ criiiis ^' ixdog piscis quia solus inter j>isces fere hirsutus sit." 



X The references in a general way appear to include all the Sirenians then 

 known.
