 up (lie cliaractcrs of M/jonoi/ics so stringently that all the European and Asiatic 

 forms sliail be excluded if possible. 



Though we adopt the term "Mi/onofr.cs" i'ur what Professor IJaird called 

 I lemiolomys, we do not sup|)ose that Kafinesquc had any idea what he was 

 about wiien he invented it. But there stands the name "Mynomes praten- 

 sis ", l)ased upon Wilson's IMeadow Mouse, afterward Arvicola i)ennsylvanica 

 ol' Ord, which is also Arvicola riparius of Ord. We do not see how the 

 name can l)e rejected, seeing that his type — a now well-known species — Fs 

 mentioned; and, after all, it is perhaps just as well that he did not try to 

 explain what he meant.

"This should stand, in strietness, oa thu specific name, with which Ord antedates Kaflnesqiin. 

 Since, however, the nan;j is simply bused, without sufllcient description, upon a scarcely recognizable 

 figure incidentally introduced in an ornithoh)gical work, I have preferred to a<Iopt tbu same author's 

 liroperly-cbaracterizcd term yiparius, though subsequent in point of date. Though I am anurc that this 

 course is, technically, indufensilile, such slight latitude of choice stands to common sense, and infiingos 

 upon no author's rights, as Orel's earlier term cuts Rafinesi|Uo out of bis.

 "Tlio description ipioted by Sabine " * under title of .1. xatithoyualliu (hies not l)eloug to this animal, 

 but to a much smaller species, which I have referred to the J. pennsi/lcanica of Old."
