of, tliore arc no synonyinical points to be determined in this case. There 

 are, however, several discrepancies between the description of Audubon and 

 liachnian and the characters of the animal which Hoy, Kennicott, Baird, and 

 ourselves describe. Thus, they say, "mammae, six pectoral and four abdom- 

 inal." We fiiil to realize "clieeks yellow," thougli, perhaps, they arc a little 

 brigliler tlian surrounding parts. The dimensions given, 4 inches (()r length 

 of liead and l)ody, are so much greater (by a full incii) that possibly the fig- 

 ure " 4" may be a typographical error ; but then the tail, 2J, is nearly as much 

 in excess of wiiat we tind. It is barely possible, alter all, tiiat, as Professor 

 Baird iiints, none of our specimens are what Audubon and Bacliman called 

 mic/iiganciisin. In tiiat event, and if positively distinct from Audul)on's and 

 Baclinuurs animal, they would, of course, bear the name of "bairdii", and 

 "michiganensis" And. & Bacii. be relegated among the unnumbered synonyms 

 of /cucojiiis. But, in the seeming impossibility of determining this point, it is 

 better to let mic/iigaiiensis stand for what we now describe.
