SPECIMENS OF FOSSIL W(30DS IN NATAL MUSEUM. 365 



Mr. William Anderson,^ with respect to these, writes: 



"At Port Duruford, Zulnhind, there is a cliff section con- 

 taining a bed of impure lignite, ovei'laid by a series of false- 

 bedded sands, which can be quite easily identified with 

 sections higher up the coast, which undoubtedly overlie beds 

 of Tertiary age containing marine fossils. , . . The lignite 

 bed consists almost entirely of vegetable matter with large 

 masses of timber, and probably having an origin under 

 marshy boggy conditions. 



" The upper false-bedded sands outcrop very commonly in 

 sections of the sand-hills on the immediate shore-line, and 

 may yet prove to be of later date than Tertiary. 



" The division between the sand beds and the fossiliferous 

 marine strata below is usually a more or less sandy lignitic 

 bed (carbonaceous) containing large pieces of timber com- 

 paratively Avell preserved. This lignitic bed is not always 

 present, and then the sandy beds rest immediately on the 

 fossiliferous marine shales. The lower layers of the sand then 

 contain enormous numbers of fossil spores and spore-cases."" 



Immediately above the mammalian bearing shales and below 

 the lignitic bed is a thin layer w^th enormous numbers of 

 Foraminif era, which, according to G. T. Hinde, were 

 identified as more likely to be of Tertiary than Cretaceous age. 



According to R. Ethridge, of Sydney Museum, the mollusca 

 in the mammalian beds are Tertiary and possibly Eocene, 



The general arrangement of the strata above described has 

 been confirmed by Mr. A. Hammar, Government Surveyor, 

 who informs me that further north in the St. Lucia district 

 he observed the following section : 



(1) at the top a reddish, loose sandstone about 10 ft. in 

 thickness ; 



(2) a seam of sandstone with much limonite about 5 ft. 

 in thickness ;

- I regret that it has not been possil)le to obtain specimens of these 

 *' spores."
