This species, though very closely allied to T. Hemnnyta, 

 may be readily distinguished by its more arched anterior 

 wings, and the more ochraceous colouring of the yellow in the 

 posterior wings, with several other difierences. It may be re- 

 garded as intermediate between T. Henningia and T. Egialea.

 tory of the Quadrupeds of Paraguay, or in Dr. Rengger's ' Naturgeschichte

 only one ever published), however, of an English translation from the 

 original Spanish of the former author, by Mr. W. Perceval Hunter, F.G.S. 

 (Edin. 1838), we are informed (p. 163) that " Buftbn describes a third 

 species of Anteater j" and the Don proceeds, somewhat scoffingly, to ques-
