 Clavulina, sp. 



Carpenteria, sp. ITumerous fragments ; some very fine charac- 

 teristic pieces. 



No. 658. A hard dolomitic limestone occurring with chalk-like 

 rock on plateau. 



The material of this specimen is finely granular, and disseminated 

 throughout are fragmentary pieces of organic origin, which can be 

 determined as branching Lithothajnnion, with many foraminifera, 

 usually badly preserved. 



The foraminifera are undersized and thin-shelled as a rule, 

 and seem to indicate, together with the abundant and partially 

 decomposed calcareous algae, that this rock represents the soft 

 mud of a shallow lagoon. 



Foraminifera : 

 Spirohculina, sp. Frequent. 

 Textularia rugosa (Rss.). Very rare. 

 ? Nodosaria [Bentalina), sp. One example. 

 JDiscorlina, sp. (a small turbinoid form). Rare. 

 Planorhulina, sp., near larvata, P. & J. Frequent. 



^ On the chief road-clearings Mr. Ross has had the distances blazed on the 

 tree trunks every five or ten chains.
