670 General Notes. [ August, 
Dinosauria, and that principally on this ground the formation has 
been referred to the Cretaceous series. A genus of uncertain 
affinity, Champsosaurus (Simedosaurus Gerv.), has hitherto been 
regarded as peculiar to the Laramie. In France, however, it has 
been found by Dr. Lemoine near Reims, in the Suessonian 
ocene, associated with Mammalia. JI am now able to announce 
that the same association occurs in New Mexico in a formation 
which lies below the typical Wasatch Eocene, and which may be 
the Puerco. Champsosaurus is found imbedded in the same 
matrix with species of Triisodon, Periptychus, Hyracotherium, and 
a species probably of Phenacodus. Portions of a dozen vertebre 
were sent me, mingled with the teeth of the last:named mammal, 
and they appear to belong to one animal, and are unworn, As 
usual with vertebrz of the Laramie, the neural arches are lost. I 
describe the new species as follows: Scent 
Champsosaurus australis, Cervical vertebra distinguished by 
the superior transverse extent as compared with the longitudinal 
and vertical. The dimensions are about those of the C. /aticollis. 
There is a similar median inferior low keel. The outline of the 
pierced by a foramen below the base of each diapophysis. on- 
articular surfaces of centrum marked with a delicate thread-like 
sculpture. Diameters of cervical centrum: anteroposterior M. 
012; vertical 014; transverse 017. Diameters of a dorsal: 
anteroposterior .o13 ; vertical .o12; transverse .015. The pi 
vical vertebra is wider and more transverse than in either ©

CoLors oF GEoLocicaL Maps.-—Professor Renevier, of hae 
sanne, general secretary of the commission appointed by the 
Geological Congress of Paris of 1878, to unify the colors of geo- 
logical maps, makes a report which is published in the Bulletin 
of the Vaudoise Society of Natural Sciences. Sub-committees 
were appointed in the following countries: Germany, Spain, FoF 
tugal, Russia, France, Italy, Switzerland and the United states 
The fullest reports were made by the Italian and French com 
mittees, and the colors they suggest are as follows:
