3. On some Extinct Fishes of the Teleostean Family Gono- 

 rhynchidoe. By A. Smi'i'ii Wood-wakd, F.Z.S. 

 [Received March 13, 1896.] 

 ■; ■■ ,\ ^ (Plate XVIII.) 



In his well-lniown work ' Epcherches snr las Ossemens Fossiles* 

 Baron Ouvier describes several fossil remains of fishes from the 

 Upper Eocene gypsum of Blontniartre, near Paris, which he briefly 

 discusses with only proyisional results and no definite names. 

 Most of these have been redesciibed 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 incerice 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 

 helong to a nearly extinct family of Teleosteans (Gonorhynchidse) 

 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 gonorrijnchits, 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 similar form." The small mouth, extended premaxillse, 

 and absence of teeth are also noticed. 



A niore.impert'eet example, not improbahly of the same species, 

 from Montniartre, 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. squamosseus. 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.
