about the same dimensions as the lateral appendages of the forms referred 

 by Gnrley to C. wrightii, and is considerably smaller than the pod- 

 like bodies described under this name from the Skiddaw slates. In outline 

 and the position of the raised rim it agrees best with the appendages described 

 ])y Gnrley as C . c u r v i 1 i n ea t u s from the Beekmantown at Point Levis, 

 and the Upper Beekmantown of Nevada. We refer it 

 therefore with some doubt to the latter species. 



In the United States National Museum there is a 

 small suite of slabs, collected by C. D. Walcott in 1890, 

 on the Mettanee river, ^ mile above the North Granville

 and indeterminate, but in general resemble flattened 

 or burst apple seeds. In one or two places two of these films are united 

 in such a fashion as to suggest that they originally belonged together 

 [pl.l7, fig.l6]. On a label written by Dr Gurley, one of the latter specimens 

 is sketched, and this is added, " resembles C. oblong us most, but more 

 rounded oval." The material in hand does not allow any definite identification 

 or description and we have been unable to secure better specimens at the 

 original locality.

As the material referable to Dawsonia which has been found at the 

 Deep kill is considerably larger and of a more varied nature than that of 

 Caryocaris, it allows a more positive identification and expression of opinion 

 on the taxonomic relations of these bodies. 



Nicholson [loc. cit.~\ proposed the name Dawsonia for the "ovarian 

 vesicles " of graptolites which he had described in his Monograph of 

 British Graptolites [pt 1, p.71, fig.4] and which he later on ^ designated as 

 " gonangia " of graptolites. He desciibed f oui- species, viz D . acuminata.
