same strata and locality yielding those previously diagnosed by 
W. H. Baily. The beds containing these fossils he termed the 
“Tzinhluzabalungu Deposits.” They consisted of five horizontal 
layers, the lowest resting unconformably on the older rocks of 
the Karoo Formation. In descending order they were tabulated 
thus :— 
= 
Zone of Ammonites Gardent, 
2 Gastropoda-Bed. 
3 Ammonite-Bed. 
4 Trigonia-Bed. 
5 Sandstone with fossil wood, &c. 
These zones or beds, stated to extend as far as St. Lucia 
Bay in Zululand, contained a fauna which was regarded as 
belonging to the Chalk, Upper Greensand and Lower Green- 
sand horizons, and about twenty of the molluscan species were 
referred to Southern Indian Cretaceous forms. The deter- 
minations, with their horizons, embraced the following species ; 
those without author’s names being new : 
Most probably White Chalk (= No. 1 of section). 
CEPHALOPODA. 
Ammonites Gardent, Baily. 
Probably Upper Greensand (= No. 2 of section). 
CEPHALOPODA. 
Ammonites Umbolazi, Baily. 
GASTROPODA. 
Avellana ampla, Stoliczka 
Cerithium (Fibula?) delectum, Stoliczka 
Cerithium kaffrarium 
Chemnitzia undosa Forbes (= Zurritella Meadt, Baily, Chemnttzta 
Sutherlandi, Baily) 
Euchrysalis gigantea, Stoliczka (= Zurritella Renauxtana, Baily) 
Fasciolaria assimilis, Stoliczka 
Fasciolaria ( Voluta) rigida, Baily 
Lagena nodulosa, Stoliczka
