5° to the South. The occurrence of zamias at this locality would indicate' 

 that the Stripermatoor beds, at least, are older tlian the Cuddalore forma- 

 tion, in which, as I have mentioned, exogenous plant remains only have 

 been met with (excepting some grass-like remains) ; but, until the physi-

 S''°"P^" cannot affirm that the laminated clays of Striperma- 



toor are not considerably older than the feiTuginous formation which 

 forms the escarpment near Poouamallee. 



I content myself with pointing out this possibility as a matter of som© 

 interest for future investigation. I am unable to say what is the extent of 

 the sandstone formation in question. From a remark of Captain New- 

 bold it would appear to extend to the South-west as far as Conjeveram 

 at least, a distance of SO miles; but I have seen no definite statement 

 upon the subject. 



Beds similar to the above occur also, according to Newbold, at

 been described by my brother in a former volume of the Memoirs, and it 

 is suo-gested by him, on physical grounds, to be a comparatively recent 

 formation, although unfossiliferous, and not associated with any beds of 

 ascertained age.
