O. C. Marsu. 
Lemuravus distans, gen. et sp. nov. 
The first announcement of the order Primates from the Tertia- 
ry of this country was published by the writer, Oct. 8th, 1872, 
and subsequently appeared in this Journal, (vol. v, p. 405, Nov., 
1872). In this paper, three genera of the Limnotheride, viz: 
Limnotherium, Thinolestes and Telmatolestes, previously described 
by the writer, were shown to belong to the lower Quadrumana, 
the principal parts of the skeleton being very similar to those 
of Lemurs, while the jaws were somewhat like those of Marmo- 
sets. The number of teeth was stated to be greater than in 
any known forms of the order. Subsequent researches have 
fully confirmed this determination, and many new facts ma 
now be added in regard to the characters and affinities of this 
Mesacodon, Bathrodon, and Antiacodon, described by the writer.* 
e genus Lemuravus, here described, is nearly related to 
Hyopsodus Leidy. The latter proves on investigation to belong 
to the Primates, and not to the Ungulates. This is shown by 
* Antiacodon nanus Marsh was redescribed by Cope, several months later, under 
the name Anaptomorphus amulus. Limmnotherium affine Marsh was likewise re- 
described by the same author as Zomitherium rostratum Cope.
