This sample contains shells of brachiopoda and 
numerous foraminifera. Especially note¬ 
worthy amongst the latter is the large discoidal 
form, Orbitolites complanata, Lam. 
A thin section of one of the rock-fragments 
shows it to consist of foraminiferal tests 
{Orbitolites, Amphistegina, Sigmo'ilina, Globi- 
gerina, and Truncatulina), echinoid spines, 
brachiopods and lamellibranch shell-fragments. 
Glauconite is seen invading the interstices of 
the organic structures.

Notes on Bore No. 1. 
From 154 to 210 feet the strata passed through are evidently of Kalimnan 
age. 
The sample 208 to 210 feet seems to contain a mixture of Kalimnan and 
Janjukian species, as shown by the occurrence of Glycimeris convexus and 
G. halli, together with Limopsis insolita and the fragments of polyzoal rock. 
Samples 210 to 244 clearly indicate a Janjukian facie3.
