REVIEWS 93 
Many new figures have been added to the work, but some have been 
retained which should have been rejected. Some minor errors are 
noticeable. Dr. Dall will be surprised to see that he is cited on page 
177 as a writer on extinct frogs! The edition as a whole is very welcome 
to every student of extinct vertebrates; we only regret that the English 
edition might not also be brought up to date and the mammals included.

“Beitrage zur Kenntnis der Oligozinen Landsiugetiere aus dem 
Fayum (Aegypten).”’ By Max ScHLossEr.  Beitrdge sur 
Paldontologie und Geologie, XXIV (1911), pp. 51-167; Pls. 
IX-XVI. 
Perhaps no discoveries of extinct animals in recent years have 
excited more general interest than those of the Oligocene of the Fayum 
in Africa, as first made known by Beadnell and Andrews and later by 
Osborn. The present contribution by Schlosser, based upon extensive 
collections made for the Stuttgart Museum, adds very materially to this 
interest. In it he describes and figures new creodonts and rodents, 
an insectivore, a bat, and three new genera of primates of especial 
interest. And our knowledge of the Hyracoidea is also materially 
increased by the addition of much new material—*“‘so dass die Andrew- 
sche Monographie auch fiir diese Gruppe volkommen veraltet erscheint.”’ 
Most interesting of his discoveries is the new simiid Propliopithecus; 
and but little less so are his new genera Parapithecus and Moeropithecus, 
the former representing a new family of anthropoids. Propliopithecus 
he believes has a direct genetic relationship with Homo: ‘ Aber auch fiir 
die Ableitung der Gattung Homo und wohl auch der Gattung Pithecan- 
thropus (wenn nicht mit Homo identisch) von den oligozinen Genus 
Propliopithecus besteht kein prinzipielles Hinderness, denn in den oben 
beriicksichtigen Merkmalen hat die Gattung Homo mit Propliopithecus 
sogar entschiedene gréssere Aehnlichkeit als alle lebenden Simiiden- 
Gattungen.”’ And he thinks that the recognition of this African ante- 
cedent of Homo is to be welcomed as doing away with the necessity of 
resorting to eoliths as proof of the existence of ancient Man. “If now 
Propliopithecus is the direct ancestor of Man the impossibility of his 
making eoliths is evident, since Propliopithecus had probably only the 
body dimensions of a human infant, and that so small a creature could 
have used stones of the size of the usual eoliths no one will seriously 
affirm.” In the evolution of the Hominidae, aside from the gradual 
increase in body size, there has been a shortening of the premolars, a
