11. — Ceetaceotjs Fishes from Mexico. 



IN a recent description of a series of Jurassic and Cretaceous 

 fossils from Mexico (Palseontograpliica, vol. xxxvii. pp. 189- 

 194, pi. xxviii. figs. 14-18, pi. xxix. fig. 3, pi. xxx. figs. 3-5, 8-10), 

 Dr. J. Felix refers to some fish-remains from the Neocomian of 

 Cerro de la Virgen, near Tlaxiaco. The new genus and species, 

 Otomitla speciosa, is founded upon a skull and badly preserved 

 trunk, apparently of a Lepidosteoid ganoid. The bones of the 

 head and opercular apparatus are externally sculptured, and the 

 dentition consists of very large conical teeth ; the vertebrse are 

 completely ossified, biconcave ; and the scales are rhomboidal, much 

 broader than deep on the ventral aspect. The imperfectly known 

 Neorhombolepis, of the English Chalk, presents several striking 

 features of resemblance. Associated with Otomitla it is interesting 

 to find recognizable remains of a species of Belonostomus, described 

 under the name of B. ornatns. The vertebrae in this fish are com- 

 pletely ossified, as in some other Cretaceous species. 



Though limited to the description of two definable genera and 

 species. Dr. Felix' contribution is of great interest as relating to a 

 region that has not hitherto yielded fossil fishes. Belonostomus has 

 now been found in the Cretaceous of Europe, India, Mexico, Brazil, 

 and Queensland ; and the geographical distribution of the genera of 

 fishes of the Cretaceous period is gradually becoming a subject con- 

 cerning which so many facts are known as almost to justify an 

 attempt at broad generalizations. A. S. W.

EOR many years the above Society has published in its Reports 

 lists of the Fauna and Flora, both Recent and Fossil, of the 

 neighbourhood of Winchester. The lists of Recent forms attained 

 some years ago to such a degree of completeness, that their repeated 

 issue seemed unnecessary. The list of Fossils, on the other hand, 

 has been rendered, through new discoveries and new views, some- 

 what antiquated, and it is a happy thought of Mr. C. Griffith to 

 issue it in a separate and more convenient form. 



The present edition begins with a short description of the Chalk 

 of Hampshire, its zones and its foldings. Then follows a list of 

 Pits and Sections near Winchester ; for each of these is given the 

 zone and a complete list of fossils, while to most are added the dip 

 and any other information of interest : twenty-five such localities 

 in the Chalk, and six in the Eocene are thus recorded. The Chalk 

 in the Winchester Anticlinal extends from the Senonian zone of 

 Belemnitella quadrata down to the zone of Holaster subglobosus in 

 the Cenomanian. From it 186 species, excluding Plants and Fora- 

 minifera, are here recorded. These are displayed in a Table, arranged 

 according to the main zoological divisions, which shows the vertical 

 distribution of each species through the zones. Thus, while the
