were collected by Captain E. J. Garden, and most of them are now 

 in tlie possession of the Geological Society of London. 



The Pondoland fossils are found in shelly Hmestones and sandy 

 calcareous clays, and are in an excellent state of preservation — in 

 one case (Nerita) even the original colour markings are still visible. 

 The fauna is particularly rich in Mollusca, of which about eighty 

 species have been recognised. There are also five species of 

 Echinoids, six of Polyzoa,* seven of Ostracoda, and eighteen of 

 Foraminifera. The last two groups have already been described by 

 Mr. F. Chapman, t Vertebrata are represented by bones of Chelonia 

 and shark's teeth (Corax). Corals, Brachiopods, the higher Crus- 

 tacea, and the Belemnitidse appear to be absent, and the presence of 

 Sponges is shown by a few spicules only.
