Olupea ; and Diplomystus is recorded, but only from the Green River 
Shales of Wyoming. The latter genus is now known also from 
the Cretaceous of Brazil! and Mount Lebanon,” besides from the 
Oligocene of the Isle of Wight.’ 
The fossil Salmonide are little known, and to the author’s account 
we would only add that the remarkable nodular concretions with 
Mallotus villosus, so well known from Greenland, are also met with 
in the Glacial Clays on the banks of the Ottawa River in Canada. 
The paleontological history of the Scopelidz and Osteoglosside is 
likewise scanty; and the only point of much interest in that of 
the Cyprinodontide is the occurrence of the now-existing tropical 
American genus Pecilia, in the Oeningen beds of Switzerland. 
Many representatives of the Cyprinide occur in freshwater Tertiary 
formations, but the majority are referable to existing genera; and 
Notogoneus, from the Green River shales of Wyoming, is the sole 
recognized fossil genus of Gonorhynchide (misprinted Ganorhyn- 
chide). The Murenide occur first in the Upper Cretaceous of 
Mount Lebanon ; and the Scombresocide, which conclude the Phy- 
sostomous order, are considered by Dr. v. Zittel to be also probably 
represented in the Cretaceous by Istieus and Rhinellus. 
The order of Pharyngognathi comprises three families with fossil 
representatives—the Pomacentride, Labride, and Chromide. To 
the first are assigned two extinct genera, Odonteus from Monte 
Bolea; and Priscacara from the Green River Shales of Wyoming ; 
and in the last are placed the Cretaceous genera Pycnosterinz, Omosoma, 
and doubtfully Imogaster. The Labride are represented chiefly by 
detached examples of the pharyngeal dentition in the Tertiaries ; 
and in addition to typical forms like Labrus and Nummopalatus, 
Dr. v. Zittel places here the remarkable Eocene Phyllodus and Eger- 
tonia. ‘The latter are also recorded from the Cretaceous, but Phyllo- 
dus cretaceus, Reuss, is not founded upon satisfactory evidence ; and 
Egertonia gaultina, Cornuel, from the French Gault, is very doubt- 
fully related to the Eocene fossils, and may perhaps be more satis- 
factorily compared with the palatine dentition of the Hlopine Protelops 
from the Turonian of Bohemia. 
The order Acanthopteri commences with the Berycide, having 
many extinct representatives. In addition to the ordinary species, 
Beryx includes numerous detached scales described under five or six 
generic names from the Plainerkalk of Saxony and Bohemia; and 
we would only remark that the English Chalk species mentioned 
(B. lewesiensis) now proves to be referable to Hoplopteryx.4 In the 
last-named genus must also be placed the so-called B. Zippei, of the 
dorsal fin of which the figure copied from Fritsch scarcely gives 
a correct impression.® The Lebanon fossil named Homonoius pulcher
