held in Leipzig during the week following Easter Sunday. In the year 
1804, Easter Sunday fell on the first day of Aprilf and the following day, 
therefore, may be regarded as the actual date of publication of the name 
Ovis montana, approximately one month after the ai)2')earance of Ovis 
cervina, and two months later than that of Ovis canadensis.
