State Museum of Natural History. 11 



descriptions of which were presented with the thirty-third report at the 

 close of 1879, several have, in the meantime, been elsewhere described, 

 and the same is true of some of those communicated with the thirty- 

 fourth report. 



In the thirty-third report the Curator communicated descriptions of 

 numerous species of fossil Bryozoans of the Upper Helderberg and 

 Hamilton Groups. The delay in publication threatened to deprive the 

 Museum of the credit of prior publication, and an abstract of the paper 

 has been published in the Transactions of the Albany Institute. 



We have now, however, every reason to believe that the present 

 report will have speedy publication, and that we may be able to remedy 

 in some degree the unfortunate delay in the publication of previous 

 reports of the Museum . 



Respectfully, your obedient servant, 



JAMES HALL, 

 Curator of the State Museum of Natural History. 



December, 1881.
