®Mehoerat, A. Sinopsis de la Familia de los Bunodontlieridoe , conser- 
v&dos en el Museo de la Plata. L& Plata : 1891, 8vo, 26 pp. 
Describes a number of Mammalian remains from the Tertiary of Pata- 
gonia, which are referred to a new family, and many of which are con- 
sidered to indicate new genera and species. The forms described as new 
include the genus Bunodontheriurri, with the species B. patagoilicum , B. 
majusculum ; the species THodtherium niinusculum and periculosum ; the 
geinis and species Anomodontheriuin nriontanum ; the genus Anisolophus, 
with the species australis , burmeisteri , and Jischeri ; the genus Oreomeryx 
(preoccupied), with the species propius, superbus , aud ruetimeyeri ; Mery- 
codon (preoccupied), with M. damesi and M. rusticus ; and the genus and 
species Rhagodon gracilor , The memoir is criticized by Ameghino in 
Rev. Arg. Hist. Nat. i, pp. 338-346, with illustrations. It is there stated 
that the family Bunodontheridce is the same as Proterotheriidce, and that 
most of the genera and species have been previously described. Bunodon- 
therium is identified with Diadiaphorus ; Anomodontherium with Thod- 
therium ; and Oreomeryx , Mery codon, and Rhagodon with Proterotheriunii 
A synopsis, with figures, is given of the family.
