appropriate to call it a sandstone kitted with lime. The rock is fine grained and 
weathers to a soft, fine, blackish sandstone; sometimes the weathered rock is 
yellow; this may be due to an inconstant small amount of clay. 
The sea-shelf of the lower shelly limestones is continued along the coast up 
to half-way to the mouth of the Umtamvuna. This end is strewn with large 
blocks of fossil wood, and fossil trees of twenty and thirty feet length are 
nothing out of the common. Fairly high hills slope steeply towards the beach 
along this portion, and it is not impossible that patches of cretaceous deposit 
are still present below the sand and vegetation of these slopes. 
There are two high cliffs on the southern bank of the Umzamba, one more 
towards its mouth and the other more inland, to the west of the waggon road. 
In the upper part of these cliffs the banks of compact limestone are thick, but 
in the beds at their foot the compact limestones are much thinner, dwindling 
to two feet and less for those between high and low water. Further up the 
Umzamba on the north bank, there is another cliff, which is formed by Table 
Mountain Sandstone. This formation also crops out on the extreme end of the 
southern bank of the river. Only about loo yards to the south of the river, 
on the sea-beach, cretaceous beds outcrop below sea-level. The coast was not 
investigated further southwards. 
Altogether some 10,000 fossils have been collected here by the expedition, 
and the following is a description of the cephalopoda contained in this collection. 
To this have been added the undescribed cephalopoda, which were bought 
from Mr J. Venter, who collected at the same locality. The other material 
is still being developed from the matrix, and will be described group-wise as 
soon as a group is more or less complete. 
NAUTILOIDEA. 
Genus NAUTILUS Breyn. 
Nautilus Woodsi n.sp. PI. I, figs, i — 3. 
The collection contains two nautilus specimens, which have been bought 
from Mr Venter. They were not described before, because I wanted to await 
the results of our Pondoland expedition. However, no further specimens have 
been found. The two specimens belong apparently to the same species. The 
small specimen, which is in good preservation, is taken as the type. 
Shell sub-globose, without umbilicus. Greatest thickness between one- 
third and one-fourth of the height of the last whorl. Height of last whorl 
somewhat less than its thickness. Last whorl indented to about two-fifths of 
its height. Periphery convex and rounded; sides less convex. Umbilical de- 
pression filled with a shelly columella. 
Surface of shell covered with very fine, close-set growth-ridges, which bend 
gently forwards in passing from the umbilical region to the sides of the shell, 
and afterwards curve more rapidly backwards in passing on to the periphery, 
where they form a broad rounded sinus. The surface of the last half of the 
whorl is also very inconspicuously undulating. Very broad and extremely low, 
heightened zones cross the shell in the same direction as the growth-ridges; 
these zones are separated by broader interspaces. The shell of the last portion 
of the last whorl is not preserved, but the cast, which is otherwise smooth, 
shows two far apart shallow grooves, which have the same shape as the growth- 
ridges. Sipho and sutures are not visible in the type. 
The paratype is badly preserved. One side has completely disappeared and 
the shell of the other side is weathered so badly, that nothing can be said of
