12. Foraminifera and Ostracoda from the Upper Cr<'fi-t'<>ns of Need's 

 Camp, Buffalo River, Cape Province. By FREDERICK CHAPMA.N, 

 A.L.S., F.R.M.S., etc. 



With two Plates, XIV, XV, and Text-figure. 



SOME little time since, I was favoured by Dr. L. Peringuey, Director 

 of the South African Museum, with samples of fossiliferous rock from 

 both the Upper and Lower Quarries at Need's Camp, Buffalo River, 

 with the request that I should examine them for microzoa. 



Although the material did not promise to yield a large number of 

 the smaller organisms other than the polyzoa, after a lengthy search 

 a small but interesting series was obtained, the results of an examina- 

 tion of which are now given. 



LIMESTONE FROM THE UPPER QUARRY. 



General Characters. This rock is a fairly compact polyzoal lime- 

 stone with a crystalline matrix (see Text-figure 18). The polyzoa 

 forming the rock constitute about 50 per cent, of the whole, and 

 there are a few foraminiferal tests present. These can only be 

 examined in thin sections of the rock, owing to the compact structure 

 of the limestone, which prevents the extraction of the small shells by 

 fracture or pulverisation. 



The following Foraminifera were met with in thin slices of this 

 rock : 



MILIOLINA cf. CIRCULARIS, Bornemami sp. 



Sections cut in various directions point to a comparison with this 

 species. It is a shallow water form, and has an e.^ensive geological 

 range. 



MILIOLINA cf. FERUSSACII, d'Orb. sp. 



An oblique section of what appears to be the test of this or a related 

 species occurs in the limestone. The chambers are evidently arranged 

 on the quinqueloculme plan. Foraminifera of this type are found in 

 all deposits ranging from the Lias to Recent.
