Echinoidea, Bracliiopoda, and Lamcllibranchia. 19 



NOTE ON THE LOCALITY. 



These fossils were obtained by Mr. J. W. Woods, of East London, 

 from Need's Camp, on the Buffalo Biver, twenty miles from the sea 

 and at an altitude of about 1,200* feet. Mr. Woods says the lime- 

 stone is " exposed in two open workings about two miles apart, and 

 the one about fifty feet higher than the other. In the lower the 

 greatest thickness is six feet and seems to be composed entirely of the 

 remains of small shells, echinids, cup-corals, and various spines. . . . 

 In the upper quarry the limestone is mainly crystalline and hard, 

 and seems to be a mass of shell of mussel type : a few ' shark's ' 

 teeth have been found in it. We had a section there of eight feet 

 to examine, and how much more exists cannot be stated as the 

 workings have not gone deeper. 



" The areas where the deposits occur are completely enclosed by 

 dolerite: they may be described as two level ten-acre lots surrounded 

 by boulders ; and were, I presume, old shore-basins or lagoons, 

 walled in by the igneous dyke, where the molluscs lived and died, 

 or into which they were gradually swept by the tide." 



The interest of this fauna is very great because it occurs at a place 

 more than half-way between the Pondoland Upper Cretaceous out- 

 crops and the main area of the marine Lower Cretaceous in 

 Uitenhage. No fossils from similarly situated beds have been 

 described, though limestones like that from the top quarry at 

 Need's Camp are known from the neighbourhood of Sand Flats 

 at about 1,200 feet above sea-level.

* This is the figure given by Mr. Woods ; it is probably too great by 100 feet, 

 as in Gamble's list of heights the Need's Camp beacon is said, on the authority of 

 Capt. W. Bailey, B.E., to be 1,144 feet above sea-level.
