DiscrssiON. 



Dr. F. A. Bather was glad to find a British geologist and 

 paleontologist tackling these complicated problems of New Zealand 

 geology with such success. Ever since he himself had described 

 Torlessia, he had wished to know the age of the supposed Maitai 

 Beds near Mount Torlesse, where this presumed annelid was found. 

 Did the Author include them in those which he now referred to 

 the Pernio- Carboniferous, or would he parallel them with the 

 Yakutat Slates of Liassic age, or would he leave them in the 

 Trias ? 



The Author, in reply, stated that the true relationship of the 

 Mount-Torlesse Annelid Beds was still one of the unsolved problems 

 of New Zealand geology. The question of their stratigraph}^ is 

 discussed by McKay and others, and the evidence seems to show
