shaped flints, sometimes one to two decimetres in diameter. Flints occur moreover 
in the whole section. The rock is corrugated everywhere into sharp edges by 
weathering. In the aloer Karangpoetih near the north east point of a limestone 
mass of the same name which is from a long distance visible from the military 
road east of Kalooë in a westerly direction as a bare cliff, beds of limestone occur 
and next to these beds of a lustrous slate, which is of black grey colour and 
contains particles of carbonaceous matter. Also a conglomerate composed of 
fragments of slate or shale is found here. The position of these layers and their 
mutual relation has not become clear to me during my short visit. 
Summarising the sequence of strata from below upwards is: 
+ 80 m. reddish grey marls and grey shales; 
+ 75 m. /imestone, grey, fine-grained, sometimes dolomitic ; 
+10 m. limestone as before, alternating with thin layers of erinoid 
limestone of reddish colour and with one or more alternating layers 
of grey marl with probably devonian trilobites and other fossils. 
This rock weathers into a red-brown sandy claystone. 
+ 25 m. grey shales, 
The rocks are gently folded and the strike is N. 80° E., which 
is. however, of little importance on account of the small extent of 
the area, where the rocks are well exposed. 
FAUNA. 
The entire fauna has been obtained from one horizon in the upper 
portion of a series of strata, about 190 Metres in thickness, appa- 
rently oecurring in conformable succession. Moreover the fossils only 
occur in the beds of marly limestone, inthe purer limestones I found 
no fossils as yet, except stems of crinoids. Hence the fossils collected 
only offer a poor representation of the entire fauna, which e.g. 
in the crystalline limestone might have had another character, but 
has entirely disappeared by the processes of reerystallisation and 
partly also dolomitisation. 
The number of specimens of the fauna found in the mar! is large, 
but the number of species is small. A rapid examination, made on the 
spot without having any literature at hand, gave the following 
species: Acanthocladia sp., Strophomena sp.? Zaphrentis sp., Melo- 
crinus (Ctenocrinus) typus Bronn., Actinocrinus sp.? and a calyx of 
a erinoid, probably belonging to the order of Carviformia, besides 
numerous Trilobites, probably of the genus Proetus and possibly 
also a Dalmania sp. and finally a form belonging to the Nautilidea. 
Excepting the corals and some of the brachiopods the lime of the 
shells has entirely disappeared, the casts being difficult to determine. 
The casts of the trilobites have been preserved best of all, as is
