and greenish argillaceous and sandy beds. Shells were found in all 

 these elay-beds, and Ammonites at different heights and in certain 

 of the strata. Many fossils are exposed on the cliffs, and washed 

 out on to the shore by the action of the sea. 



Fossil trees are seen at low water on a reef of flat rocks near these 

 caverns ; and about three miles to the southward Capt. Garden found 

 at the extreme point of the left bank of the Umpahlanyani * stream 

 a piece of fossil wood, imbedded in a rock similar to that at the 

 caves. 



About half a mile beyond the caves runs the Umzambanif River, 

 across which the cretaceous rocks are continued, appearing on its 

 right bank ; after which they are lost sight of, except at a few places : 

 the author, however, believes this formation to extend as far as the 

 Umtata River, having been informed by the late Mr. W. H. D. Fynn 

 that fossil Turtle remains were to be procured from the rocks at the 

 mouth of that river.

The late Professor Edward Forbes having entrusted to my examina- 

 tion the interesting series of fossils collected on the coast of South 

 Africa, near Natal, and brought to England by Capt. Garden :|:, to 

 whose exertions and liberality we are indebted for this valuable addi- 

 tion to the Colonial Department of the Museum of Practical Geology, 

 the following communication has been drawn up on the plan of Prof. 

 Forbes' s able *' Report on the Fossil Invertebrata from Southern 

 India §," to which collection of fossils the series here described bears 

 a close affinity, as also to the fossils from the greensand of Black- 

 down in our own country, and the Craie Chloritee of France. 



Cephalopoda. 



Genus Ammonites, Auctorum. 



There are four species of Ammonites in this collection ; the speci- 

 mens generally are in fine preservation, and of remarkable size and 

 beauty, some of them having portions of the shell still adhering. 

 All are allied to Cretaceous forms, and belong to the following 

 groups : —
