For all following identifications of the ostracodes in the Dalhousie 

 beds, I have been under obligations to Dr R. S. Bassler and E. O. Ulrich 

 who have recently prepared an extended account of some of the species. 1 

 With regard to the form above cited there appears to be some degree of 

 uncertainty in the minds of the authors referred to and they have not 

 satisfied themselves that the name given does not include diverse objects. 



Pachydomella sp. nov. 



Somewhat allied to P. longula Ulrich & Bassler, from the Coey- 

 mans limestone at Cumberland, Md., but distinguished from all other 

 members of the genus by its punctate surface.
