Traquairia was supposed by Mr. Carruthers to be a Radio- 

 larian Rhizopod. Prof. Williamson having obtained specimens 

 suggested that they were spores, and the subject is dealt with in 

 his Mem. X. Traqitairia occurs in a scattered and uncertain 

 manner in the coal balls, and, from the discovery of some 

 examples in a crushed cone, Prof. Williamson came to the 

 conclusion that Traqnairite were the macrospores of a Lyco- 

 podiaceous plant.' It is extremely probable that the association 

 of Traquairia with the crushed Lepidostrobus was merely an 

 accidental occurrence. Some authors have suggested that the 

 affinities of Traquairia may be with Azolla." There is, however, 

 very little to support this view. 



Although Prof. Hseckel, the greatest authority on the Radio- 

 larians, has rejected Traquairia from that group, still there is 

 not much evidence for claiming them as vegetable remains, for it 

 can scarcely be accepted as certain that the specimens found in 

 the crushed cone by Williamson really belong to it, as they also 

 occur with other broken up vegetable remains. I am, therefore, 

 inclined to regard Traquairia as an organism whose true nature, 

 vegetable or animal, has yet to be determined. They are found 

 in the coal balls of the Yorkshire Lower Coal Measures.
