18870. The greater portion of the left ramus of the mandible, 

 showing the first and second true molars and the alveoli 

 of the other cheek-teeth ; from a cavern in Minas Geraes, 

 Brazil. This specimen agrees exactly with the mandible 

 of the form known as C. macrocephalus, which is included 

 by Gray in C. apella. This species is not mentioned by 

 H. Gervais and Ameghino in ' Les Mammiferes Fossiles de 

 1'Amerique de Sud ' (Paris, 1880) ; but it is not improbable 

 that the so-called C. macrognathus, Lund (G. & A. op. cit. 

 p. 7), is really the same.

 like those of certain Selenodont Artiodactyla like Anthracotherium ; 

 a similar structure prevailing in many Lemuroids.

 from a cavern in Minas Geraes, Brazil. No species of 

 this genus is mentioned from the Brazilian caverns by 

 Gervais and Ameghino (op. cit.).
