56 BANGS -— THREE NEW WEASELS Reta = 
P. longicauda, and the skull shows that the real affinity of P. occisor 
lies with the xoveboracensis, and not with the /ungicauda, series. 
The distribution of this new weasel is undoubtedly rather 
northern, but is still imperfectly known. Besides the Bucksport 
series I have two males, both in white winter dress, from Moose- 
head Lake, Maine. I now believe that the “trapper’s” skin, 
without skull, got by Mr. Gerrit S. Miller, Jr., at North Bay, 
Ontario, and at the time identified by me as P?. /ongicauda spadix,' 
may in reality be an example of P. occzsor. Dr. C. Hart Merriam 
also has written me that there is a skin from Manitoba, apparently 
of this species, in the Biological Survey Collection at Washington. 
All specimens I have seen from northern Massachusetts and 
southern New Hampshire are extreme P. noveboracensis, and I have 
one undoubted example of that form from Upton, Maine.
