NOTE. 



In ])ecember, 1876, a volume of Albertype Illustrations of Devonian 

 Fossils of the classes Gasteropoda, PTEEoroDA, Cephalopoda, Ckusta- 

 CEA and Corals was published in an edition of one hundred copies, by 

 order of the Legislature. These copies were principally distributed 

 to public institutions under the direction of the Secretary of State. 



The Corals being less known than the other groups, and the prepara- 

 tion of a \-olunie u],)on this class of Fossils, and of the Bryozoa of the 

 lower and upper Helderberg, Hamilton and Chemung groups being now 

 in progress, the author has had a few copies of the plates of Corals 

 printed at his personal expense, with a view to their circulation among 

 those who may Ije interested in the subject. 



In the preparation of the volume referred to there have been already 

 made more than 600 original drawings of Corals, and 300 of Bryozoans, 

 which will soon be placed in the hands of the lithographer. 



In this condition of progress the author would beg leave to solicit 

 from scientific gentlemen and collectors of fossils, information concerning 

 localities and the distribiition of species, and also the contribution or 

 loan of specimens which may aid in the completion of the work and 

 become the means of disseminating a knowledge of this class of fossils, 

 which are so widely and abundantly distributed throughout the Palseo- 

 zoic formations of the United States.
