® Three figures of molar teeth, representing those characteristic of the Den- 
dromyine, Murine, and Sigmodontine respectively, will be found in my paper 
on Deomys (P. Z. S. 1888, p. 130, pl. v. figs. 7, 10, and 9). On that occasion, when 
describing Deomys, I had supposed the genus to form a new subfamily, not 
knowing how closely its molar teeth agreed with those of the Dendromyine, in 
which I now think it should be included.
