From the Garonne basin, besides the Pelagornis mioccenus, Delf., 



iiUied to the albatross, are now added further evidences of pelagi«;

humerus ; a second humerus is named Procellaria aquitanica ; a smaller 



one, of the size of the Cape petrel, is now named F. antiqua. Another 



humerus is named 8ida pygmcea. E. B. T.

The first part is occupied with Devonian Fishes. The genus Din" 



ichthys is fully described from new material, and the new genera As- 



terostevs, Acanthaspis, and AcantJioIepis are defined. The new species 



described are Dinichthys Terelli, Coccosteus occidentalism Asterosteus 



stenocqtJudus, Acmithaspis armatus, and Acanthohpis pustulosus. The 



second pait treats of Carboniferous fish-remaina. A full account is 



given of the " Conodonts" of the Cltfvehmd shiile, several forms being 



figured : and the author propounds and defends the theory that these 



bodies are really the teeth of Cyclostomatous fishes. The following 



new species are described: — Cladodun Htrtziri, t\ Pattersoni^ C. ya-
