The name Trielieclim, for so long a time in general use for 

 the "Walruses, proves not, as long- ago shown by Wiegmann,* von 

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

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

 originated with Artedi in 1738, in a posthumous workt edited 

 by Linne. The characters given were k> Denies plan! in utraque 

 maxilla. Dors urn iiupenue. Fistula . . . . The cita- 

 tions under Tricliechus embrace no allusion to the "Walrus, 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. Trichechus forms Artedfs "genus LI." 

 and is placed in his ''order Y, Playiurl" (embracing the Ceta- 

 ceans and Sirenians, the other genera of this order being Pliy- 

 seter, Ddplilnus, Balccna, Monodon, and Catodon), and is hence 



* Respecting the proper generic name of the Walruses, Wiegmauu, in 1838, 

 thus forcibly expressed his views : ' Die Gattung Odobenus [von Brissou,1756] 

 hiitte beibehalten werdeu mitsseu, da der ganz abgeschmackte Name Triclie- 

 cli us gar nicht dem Walrosse, sondern iirspriinglich dem Mauati angehort, und 

 von Artedi fur diesen gebildet war, um die bei einem Fische oder vielmehr 

 Wallfische auffalleude Behaarung zu bezeichueu." Archiv fur Naturge- 

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



tlchthyologia, 1738, pars i, p. 74; pars iii, p. 79; pars iv, p. 109. lu Arte- 

 di's work the name is twice written Trichechus and twice Tliriclieclius. On p. 

 74 of pars i. where it first occurs, its derivation is given, namely: "Triche- 

 chus a -&pf^ crinis $ l%do<; iriscis quia solus inter pisces fere hirsutus sit." 



t The references in a general way appear to include all the Sireuians then 

 known.
