I have not been able to compare the recent specimens in the 

 Jeffreys collection with specimens of the fossil described by Seguenza, 

 and insert this form under the above name entirely on the authority 

 of Doctor Jeffreys. It seems, however, to agree sufficiently well 

 with Seguenza's figures.
