der the name F. suhacideata, vdv cataracia on page 217, and those identi- 

 fied with the t3'pical form of P. subaculeata on pa£;e 283, of this volume, 

 in the synonymy of F. apinul icosta. On the other hand, it is to be noted 

 that the Rev. G. F. Whidborne, in his Devonian Fauna of the South of 

 England, vol. II., pt. 3 (1893), p. 155, says that F. spinulicosta and F. 

 suhacideata var cataracta, are both varieties of F. subaculeata.

Professors Hall and Clarke claim tliat the Atrypa cuboides of Sowerby, 



the lihynchonella cuboides of Davidson and other palifontologists, is the 



type of McCoy's genus 7/ij/iot/up-is as defined by King, and hence that it 



must be called Hypothyris cuboides (Sowerb)). Mr. Schuchert, however, 



who regards Ehynchoudla Emmonsi as distinct from R. cuboides, thinks 



that the specimens collected liy Mr. McConnell on the Hay and Peace 



rivers are referable to the former rather than to the latter species, and 



that they should be called Hypothyris Emmonsi (Hall and Whitfield).*
