T<un(indii({,\\\i.id CijdoUiara^.'xH us^ually (juoted tVoiii Thoiuson's 

 Annals of Philosophy (1. c, ]>. 343). It wa^, however, merely 

 published in a list of genera as ' Taniaiidua, Gray, M. R.,' and 

 the only pretense to a descri23tion consists of the letters ' M. R.,' 

 referring to Gra3''s paper in the London Medical Repositor^^ -^^ 

 Tliis i)aper contains the following list of edentates : 

 " Tamanoir, Myrinecophaga. Lin. M. jubata. Lin. 



Tamandua, Myrniecophaga tamandua. Cuv. 



Ant-eater, Cyclo|)es, G. Myrniecophaga didactyla. Lin. 



Pargolen [sic], Manis. Manis pentadactjda. Lin." 

 Here Tamandua is merel}' a common name and stands on an 

 entirely different footing from Cyclopes. A careful examination 

 of this paper will show (1) that the names in the first column of 

 this list are intended as common names, those in the second as 

 genera, and these are followed by the type or included species ; 

 (2) that when the common name is ado[)ted for the genus, it is 

 usually repeated; and (3) that genera are usually (but not 

 always) followed by the authority, e. g., Myrmecophnga Lin. and 

 Cyclopes G. Thus Tamanoir, Tamandua, Ant-eater, and Pangolin 

 are common names, while Myrniecophaga, Cyclopes, and Manis 

 are genera. The first unquestionable use of Tamandua as a 

 genus is in IjCssou's ' Nouveau Tableau,' y>. 152, 1842, where it is 

 based on Myrmecophaga tetradactyhi Linn. But as in the case 

 of Cyclolhnrus it is antedated, since Dryoryx Gloger, 1841, and 

 rroleptesj \A^agler, 1830, were also based on M. tdradactyla (uf 

 which M. tamandua is a synon3'mj. Uroleples has priority over 

 Dryoryx, and is apparently the earliest tenable name for the 

 genus.
