IS L0AVER PALEOZOIC ROCKS OF THE CATJTLEY DISTRICT. [March I913,. 



of the South of Scotland was not to be expected, because the con- 

 ditions of deposition there, in early Ashgilliau times at any rate, 

 were unfavourable to life ; hence the fauna was dwarfed or stunted, 

 and not typical. If the conditions had been favourable, the fauna 

 of the Dicellograptus-cmcepsZoKQ might have been found at a lower 

 horizon. 



Mr. Herbert H. Thomas felt sure that he was voicing the feelings 

 of all workers on the Lower Palaeozoic rocks in saying how grateful 

 he was to the Author for, in the first place, giving to Geology his 

 Ashgillian Series, and now for this piece of work which would add 

 still more to the value of the Ashgillian Series as a geological 

 division. 



The President (Dr. A. Strahan) referred to the admirable 

 pioneer work which had been done by Prof. T. McKenny Hughes 

 in this region. The term Ashgillian suggested by the Author 

 had proved convenient, and had been adopted in some of the 

 Geological Survey publications relating to South Wales. The 

 additional precision which had been given to it in this paper was. 

 of much value.
