3. On some Extinct Fishes of the Teleostean Family Gono- 
rhynchide. By A. Surru Woopwarp, F.Z.S. 
[Received March 13, 1896.] 
(Plate XVIII.) 
In his well-known work ‘ Recherches sur les Ossemens Fossiles’ 
Baron Cuvier describes several fossil remains of fishes from the 
Upper Eocene gypsum of Montmartre, near Paris, which he briefly 
discusses with only provisional results and no definite names. 
Most of these have been redescribed by subsequent observers, who 
have had additional specimens and more satisfactory materials for 
comparison; and the systematic position of some of them is now 
determined with a considerable degree of certainty. One nearly 
complete specimen, however, which still remains incerte sedis, has 
not hitherto received the attention it deserves; for it and a closely- 
allied form from the Eocene marls of Aix-en-Provence seem to 
belong to a nearly extinct family of Teleosteans (Gonorhynchide) 
which has not previously been known to occur in the European 
area. 
This fossil is first described in the second edition of the work in 
question (1822), and exhibits remains of all the skeletal parts of a 
fish about 0-2 m. in length. As Cuvier himself remarks, the 
disposition of the fins is very suggestive of that in the ‘*Gono- 
rhynque (Cyprinus gonorrynchus, Gron.)”; while “the parts of the 
head which are observable indicate a Cyprinoid with prominent 
nose, such as the Gonorhynque, the Cyprinus nasus [= Chondro- 
stoma], or a similarform.” The small mouth, extended premaxille, 
and absence of teeth are also noticed. 
A more imperfect example, not improbably of the same species, 
from Montmartre, had previously been described by de Blainville 
under the name of Anormurus macrolepidotus’ ; and its scales were 
said to be remarkably similar to those of a larger fish made known 
at the same time from Aix-en-Provence and referred to a new 
species of Cyprinus, namely C. syuwamosseus. The dorsal fin was 
described as remote and comprising 14 or 15 rays. The jaws 
appeared to be toothless, and five broad branchiostegal rays could 
be counted.
