110 A. 8. Woodioard — Belgian Neozoic Fish-teeth. 



Trigonodon by Sismonda ; ^ and a tooth specifically indistinguishable 

 from those of the Bruxellian is made known by Gervais from 

 Cnise-la-Motte under the name of Sargus? serratus. The Middle 

 Eocene fish under discussion must thus be termed Trigonodon serratus. 

 Whether the more robust and coarsely denticulated character of the 

 teeth described as Stephanodus justifies the recognition of this latter 

 genus must be determined by future discoveries of more satisfactory 

 specimens. 



Tiie most elaborate list of the typical Bruxellian Fish-fauna 

 hitherto published is that of MM. A. Eutot and G. Vincent, con- 

 tributed to Mourlon's "Geologic de la Belgique " (1880), p. 168. 

 In conclusion, it may therefore be of interest to revise this enumera- 

 tion of species in accordance with the latest researches : — 



Elasmobranchii. 

 Fristis Lathami, Galeotti. 

 Squatina, sp. 

 Myliobatis toUapicus, Ag.

The so-called Trigonodus secundus, Winkl., T. tertius, Winkl., and 

 Gijrodus navicularis, Winkl., require further examination. 



II. The Fish-fauna of the Danian of Ciply. 



M. Houzean's collection comprises teeth and other remains from 

 two horizons in the Ciply series — the " Craie brune phosphatee " 

 and the overlying remanie bed known as the "Poudingue de la 

 Malogne." The latter is evidently derived, at least in great part, 

 from the former, and its fish-remains are essentially the same. 

 Seven species only seem to be worthy of special note.
