but the name was not published in Latin form until 1827, when 

 it appeared in Lesson's ' Manuel de Mammalogie,' p. 309. As 

 early as 1803, Blumenbach named the same species Tatu novem- 

 cincta* and in 1809 figured it under the same designation in his 

 'Abbildungen Naturhistorischer Gegenstiinde,' No. 83. Tatu, 

 having at least 24 years priority, should therefore replace Tatusia. 

 The peccaries are almost universally placed in the genus Dico- 

 tyles erected by Cuvier in 1817, but in 1814 Fischer proposed 

 Tayassu^ a modified form of the native name, for the same 

 group. Fischer recognized two species, Tayassu pecari, based 

 on Sus tajacu of Linnaeus, and Tayassu patira. He gave full ge 

 neric and specific descriptions and a list of synonyms for each 

 species. To see that Tayassu pecari and T. patira were intended 

 as scientific and not as vernacular names, it is only necessary to 

 notice that they are used in precisely the same way as Sus sethi- 

 opicus, Tapirus ainericanus, and many others on the pages imme 

 diately preceding or following the descriptions of these species. 

 Dicotyles therefore becomes a synonym of Tayassu and necessi 

 tates a change in the family from Dicotylidse to Tayassuidse. 



The kinkajou of tropical America is usually known as Cerco- 

 leptes, although it has at least 3 earlier names (Potos Cuvier and 

 Geoffroy, 1795, Kinkajou Lacepede, 1801, and Caudivolvulus Du- 

 meril, 1806), which were given as synonyms of Cercoleptes by 

 Illiger when he redescribed the genus in 1811. All of these 

 genera were based on the same species, and Potos J should be 

 adopted as the earliest available name. 



Kaup's genus C/irysothrix, described in 1835 for the small 

 squirrel monkeys, is also antedated by the native name Saimiri, 

 which was used as a subgenus by Voigt in 1831. Voigt pub 

 lished the species as Simia (Saimiri) sciurea, and his Saimiri 

 should have preference over the later Chrysothrix.

 gabe, 1821, 111. The first edition of this work appeared in 1779, and the 

 name may have been published much earlier than 1803, but I have not 

 been able to examine any of the first six editions.
