870 General Notes. | August, 
tilia; Aves: Gastornis edwardsi, Remornis heberti, Eupterornis 
remensis Of the above, two genera, Ptilodus and Champsosau- 
rus appear to be absolutely identical in France and New Mexico; 
some of the others have near allies in New Mexico, but of iden- 
tity there is not yet certain evidence. 
In Europe, as in America, the Suessonian epoch ushers in the 
genus Coryphodon. Hyracotherium also appears (Pachynolophus 
gaudryi Lem., is a Hyracotherium), and Pliolophus. A num 
of other genera are probably identical in North America and 
France, as Miacis, Opisthotomus, Phenacodus, and Pantolestes, 
with Lophiodon and Dichobune, not yet found in America. Hy- 
zenodictis and Plesiadapis hold over from the Cernaysian fauna. 
Uniformity of nomenclature requires that the Suessonian, in- 
troduced by D'Orbigny, should replace the name Wasatch, which 
was given by Hayden many years later} In like manner the 
Cernaysienne of Lemoine is identical with the Puerco of Cope, 
and the latter name has six or seven years priority. So also 
the genera Ptilodus? and Champsosaurus? were named first m 
America 
The genus Gastornis proves to be one of the most remark- 
able which paleontology has brought to light. It is the only bird 
known, in which the cranial sutures are persistent, and it has indi- 
two and a half meters. 
Note-—Since the above was written a well illustrated paper 
from the Bulletin of the Geological Society of France has come to 
hand, which describes the species of Neoplagiaulax Lem. 106 
pe, N. cocenus, differs from the Ptilodus medi@vus n lacking 
the third premolar tooth from the lower jaw.—Z£. D. Cope. 
MINERALOGY.* 
EMPHOLITE, A NEW MINERAL.=——M. L.-J. Igelström has recently 
described a new mineral from Hoérrsjoberg, Sweden, which, oc 
curring in minute, generally microscopic crystals, has rece: 
the name empholite, from éugwiciw, to hide. ns pee 
The crystals are white, transparent, and very brilliant, having 
a hardness of 6 or over, and belonging to the orthorhombic T 
tem. They have an easy cleavage parallel to the crystallograph
