"Manati Trichechus australis."=West Indian Manatee, Trichechus man- 

 atus, (vid infra). 



The Trichechus manatus of Linnaeus' tenth edition of the Systema 

 Naturae is the only species enumerated for the genus in that edition. 



The subsequent arrangement in the twelfth edition, by which the 

 W T alrus was given place and precedence in the genus Ttichechus, led to its 

 early adoption for the Walrus, the generic name Manatus of Tilesius 

 (1802) being substituted for it in the case of the Manatee. This arrange- 

 ment, due to the rejection of the tenth edition of Linnaeus by earlier 

 systematists, is not now sanctioned, Trichechus in the generic sense, 

 being solely applicable to the Manatees. 



Linnaeus gives the habitat of the Manatee described in his tenth edition, 

 as, "Habitat in mari Americano," referring in his synonymy to the 

 "Manatus" of Rondelet, Gesner and Hernandez. The page reference 

 to Gesner appears to be incorrect, nor can I find any unmistakable allusion 

 by that fanciful author to such an animal. Both Rondelet and Hernan- 

 dez give the West Indies as the habitat of the "Manati," the latter 

 author stating this was the name applied to it by the Haitians. The 

 West Indian Manatee should therefore stand as the type of the family 

 and genus, Trichechidce et Trichechus, under Linnaeus' original name, 

 Trichechus manatus. Its more important synonyms are : 



Trichechus manatus a. australis Gmel. , Syst. Nat., 1788, 60. (in part.) 

 Manatus australis Tiles., Jahrb. f. Naturg., "1802," 1. 23. 

 Manatus americanus Desm., Nouv. Diet. Hist. Nat., 1817, xvii, 262. 

 Manatus latirostris Harlan, Jour. Acad. Nat. Sci., Phila., 1823, iii, 94. 



The Manatus inunguis Natterer, "Cat. msc. 1830," (quoted from Hart- 

 laub) is considered to be another good American species, and 

 Manatus senegalensis Desm. (Nouv. Diet. Hist. Nat., 1817, 262.) is 

 the name of the Old World form, both of course bearing the generic 

 title of Trichechus, as now understood. For a comprehensive list of the 

 synonymy of the family, with voluminous commentary and history, the 

 student is referred to Dr. C. Hartlaub's paper in Zoologische Jahrbiicher 

 i, 1886, pp. i-ii2. 



Trichechus being inapplicable to it, the Walrus has been placed by 

 some modern writers in the genus Odobcznus, attributed to Linnaeus 

 (Syst. Nat., 1735, 39) and adopted by Brisson, (Regne Anim., 1756, 48), 

 who applied it to both the Walrus and Manatee. This name is not only 

 objectionable in part for the same reasons as those given for Trichechus^
