The Jupua and Curetu dialects are properly one and the same, 

 the difference which appears in their vocabularies arising simply 

 from inequality in the ears and the orthographies of observers. 

 This is evident by the following comparison of the vocabularies of 

 Martins (German orthography) and Wallace (English orthography) : 



These two, the Jupua and Curetu, together with the Jauna and 

 Cobeu, form with the Tucano a group of dialects closely related 

 among themselves ; and they are a branch of the same mother 

 tongue as the Betoya, Tama, Pioje and Correguage, which, in turn, 

 present also merely dialectic differences between each other.* 



In spite of the imperfect materials yet available to study this 

 extended family, the relationship of its scattered members is de- 

 monstrable. To illustrate it, I submit the following : 



Comparative Vocabulary of the Betoya and Tucano Dialectic 



Groups. 



Betoya Group: B.=Betoi; C. = Correguage ; P. = Pioje; T. =Tama. 

 Tucano Group : Cob. r= Cobeu ; Cur. = Curetu ; Jup. = Jupua ; Tuc. = 

 Tucano. 



* Dr. PfaflF (u. s. p. 603) has compared five words of the Tucano, Coretu and Cobeu, pre- 

 senting similarities ; and Dr. Ernst {Zeitschrift fur EthnoL, 1891) has shown similarities of 

 six words in Tamas and Tucano ; but a general survey of the stock has not heretofore 

 been oifered.
