consideration the genius of our language forbids it. To have 

 left these terms in French would have been inexpedient for self- 

 evident reasons ; and the idea of giving a class in Latin, an order 

 in French, &c., presented too revolting a medley. By giving 

 them all in Latin, the common language of science, these objec 

 tions vanished." (p. iv.) 



Cabassous, instead of Tatoua, is therefore the earliest tenable 

 name for the naked-tailed armadillos, and the species given by 

 Trouessart, including the one added by Miller, will stand : Cabas- 

 sous unicinctus (Linn.), C. loricatus (Natt.), C. hispidus (Burm.), 

 C. (Ziphila) lugubris (Gray), and C. (Ziphila) centralis (Miller). 



Other French names used by Cuvier for armadillos, which 

 McMurtrie endeavored to preserve by putting them in Latin 

 form, are : Apara, based on Dasypus tridnctus; Cachicamus, includ 

 ing D. novemdnctus and D. septemdiictus ; and Encoubertus, includ 

 ing D. sexdnctus and D. octodedmdnctus. These names, however, 

 are untenable, as they were only common names prior to 1831, 

 and other generic terms had previously come into use for the 

 groups to which they were applied. Thus Apara is antedated by 

 Tolypeutes Illiger, 1811, Cachicamus by Tatu Blumenbach, 1803, 

 while Encoubertus is a synonym of Eaphractus Wagler, 1830, and 

 Dasypus Linnseus, 1758. 



Thomas* has already called attention to the fact that Cyclopes 

 Gray, 1821, is the earliest tenable name for the two-toed anteater 

 (Myrmecophaga didactyla Linn.), usually referred to Cydothunis. 

 But as he merely mentioned it in a discussion of the names in 

 Gloger's ' Handbuch,' it has been apparently overlooked, and it 

 may therefore be worth while to refer to it in this connection, as 

 Cydothurus still remains in use. As a matter of fact, Cydothurus, 

 although usually quoted as dating from 1825,f is merely a nomen 

 nudum in this reference, and was first published as a valid genus 

 in 1842, in Lesson's ' Nouveau Tableau Regne Animal,, p. 152. 

 There are at least three other genera based on Myrmecophaga 

 didactyla: Eurypterna Gloger, 1841, Myrmydon J Wagler, 1830, 

 and Didactyles F. Cuvier, 1829, which are actually earlier than 

 Cydothurus, so that the latter name is clearly untenable and 

 should give way to Cyclopes.
