8 PRIMATES, 
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 Mammiféres Fossiles de 
VAmérique de Sud’ (Paris, 1880); but it is not improbable 
that the so-called C. macrognathus, Lund (G. & A. op. cit. 
p. 7), 1s really the same.

like those of certain Selenodont Artiodactyla like Anthracotherium ; 
a similar structure prevailing in many Lemuroids.

Gervais and Ameghino (op. cit.).
