Samples found associated with the clay at Zircon Creek, 2^ ft. below the surface, 

 collected 13th January, 1909. 



Zircons have been previously recorded by Cox (24) from the western slopes of 

 the Southern Alps, and possibly from Doubtful Sound, Otago. They are also pre- 

 sent in Snares granite {q.v.). 



K 2618 contains a few microscopic zircons. 



K 2619 is probably a weathered flint. Locality, same as K 2649 (chalk).
