INDEX 



TO THB 



GENERA OP ANIMALS AND PLANTS IN THE CATALOGUES, 



JV. B. The names of the Animals are printed in Italics : those of 

 the Plants in the Roman character. 



[Corrections, if-c. Sickness rendered it necessary to commit the examination of 

 the proof-sheets of a part of the preceding 1 Catalogue of Plants to other hands ; 

 and some errors on this account were almost unavoidable. The most important is 

 the insertion of parallel lines (il) before many species. These have no meaning 1 , 

 and should be all struck out. 



I have recently ascertained, through the kindness of a correspondent, that there 

 is a place near Utica, New York, by the name of Newport, where without doubt 

 trilobites may be found. Hence the remarks on pag-e 250, upon Brong-niart and 

 De la Beche's statement about the Calymene, were unfounded and needless. 



Professor Emmons informs me, that he has recently found in place, in the moun- 

 tains a little northeast of Williams College, the peculiar granite described on pag-e 

 159 as scatterred in bowlders over Hoosac Mountain : thus furnishing 1 a confirm- 

 ation of my suggestion concerning the origin of this rock, and rendering it proper 

 to mark a deposit of granite in that region on the Geological Map of the State. 



For the reason mentioned in the first paragraph, (sickness) the following index 

 will not be found in all the copies of this Report ; since it was necessary for the 

 binder to proceed with all possible despatch, in order to fulfil his engagement by 

 the specified time for the delivery of the work. As such an index would be partic- 

 ularly serviceable to naturalists who might wish to consult the Catalogues in 

 this Report j I have judged it best to insert it in as many copies as possible.]
