a Thanks to the recent careful revision of this genus by Mr. W. E. Clyde Todd (Ann. 

 Carnegie Mus., viii, 1913, 507-603), but little trouble has been encountered in its 

 treatment here. Mr. Todd's paper is such a thoroughly excellent example of pains- 

 taking, conscientious, systematic work that I find myself unable to disagree with his 

 conclusions except in a matter of mere detail (see p. 429). 



Acknowledgments are due Mr. Todd for his coiu-tesy in allowing me to use his 

 measurements and thus saving me considerable time and trouble.
