In August, 1859, I published this genus in the Canadian 

 Naturalist and Geologist and described three species under it (7* 

 longirostra, C. Panderi, and C. Volhorthi ; the latter two from 

 the Black Biver and the former from the Chazy limestone. Shortly 

 afterwards Prof. Hall proposed the name Triplesia for it, but he 

 did not describe any of the internal characters. He dated his 

 genus back to 1858, although it was not published until October 

 or November, 1859. The twelfth Annual Beport above cited, in 

 which the genus Triplesia was first made public, is stated (on 

 the cover) to have been '' made to the Assembly, March 15, 1859." 

 The only other date on the cover is "Albany, 1859." The first 

 six pages of the report are occupied by the business matters of the 

 Begents relating to the affairs of the University. Then follows 

 a title-page to the paleontological portion of which the following 

 is a copy, " Contributions to the Paloiontology of New York; 

 being some of the results of investigations made during the years 

 1855-56-57 and 58." At the foot of the page is the following 

 note. " The following notices and descriptions of new genera^ 

 with other investigations have been communicated^ in part 

 or entirely, at different times to the Albany Institute; to the Re- 

 ports of the Regents of the University on the State Collections of 

 Natural History, for the years 1856 and 1858 ; to the American 

 Association for the Advancement of Science, and are already 

 printed in the third volume of the palaeontology of the State of 

 New York. No other date of publication is given either on the 

 cover or title-page. The 3rd volume of Palaeontology of New 

 Tork was not published until 1860. Upon examining the other 

 Beports and proceedings referred to, I am satisfied that the genus 

 Triplesia was not published in 1858. At all events the date given 

 by Prof. Hall must be regarded as doubtful and can have no au- 

 thority until he shows in what work he published the genus in 

 1858. As to the time of the publication of the Twelfth Annual 

 Beport, the following are the facts, as nearly as I can ascertain them.
