REPORT. 



Albany, December, 1889. 



To the Honorable the Regents of the State of Neio York: 



Gentlemen. — The duties of the State Geologist for the past 

 year have been, almost entirely with the collection and prepara- 

 tion of material for Volume VIII of the Palaeontology of the 

 State. In the report of the State Geologist for 1888, which has 

 been printed during the past month, I have given a short state- 

 ment of the character and contents of Volume VII of the Palaeon- 

 tology which was published last year. I have also there given 

 some account of what has been done in the collections and prepa- 

 rations made for the publication of Volume VIII, which I need 

 not repeat in this place. In that report I have communicated a 

 list of the genera of Palseozoic Brachiopoda arranged under the 

 several families, for the purpose of showing the scope of the 

 work. A list of the microscopic and other preparations for illus- 

 trating the structure of these fossils. The plates indicated as in 

 progress in the last report have been completed, and others are 

 already prepared for the lithographer. 



There are 300 pages of manuscript ready for the printer and the 

 printing commenced, about fifty pages being already in type. A 

 large part of the manuscript is descriptive of the Inarticulate 

 Brachiopoda, and for the illustration of the genera under this 

 order thirteen plates will be required. Of this number eight 

 plates have already been lithographed, and drawings for the 

 remaining five plates are prepared for or already in the hands 

 of the lithographer. 



In order to give a better conception of the character and extent 

 of the inarticulate division of the Brachiopoda, I append a list of 

 the genera which have been recognized and described by different 

 authors under the several families. The greater number of the 

 genera here recorded have been illustrated either upon the first 

 thirteen plates or in the text of the volume.
