of Rhinelander. Average measurements of two males : Total 
length, ii6 mm.; tail vertebrae, 39.5 mm.; hind foot, 14 mm. ; 
Average measurements of three females : Total length, 1 14.5 mm. ; 
tail vertebrae, 38 mm. ; hind foot, 13.2 mm. 
Sorex hoyi Baird. 
Hoy's Shrew. 
Baird's type of Sorcx hoyi was a male collected at Racine, 
Wisconsin (7) ; two males, including the type, are recorded by 
Professor Baird from that locality (8). There is a shrew in the 
Milwaukee Public Museum collected in 1879 by Thure Kumlien 
in Jefferson County ; this specimen, a female, bears the label hoyi, 
but I have been unable to examine it critically, and, being mounted 
with the skull inside, the species has not been positively determined 
by the author. 
Neosorex palustris (Kichardson) . (Plate III.) 
Marsh Shrew. 
I secured four specimens of Neosorex palustris near Rhine- 
lander in the swamp where I caught Sorex richardsonii. The 
four Neosorex were all trapped in the same runway, and, though 
the trap was in the runway over two weeks, no other species were 
captured there. The runway entered a mass of sphagnum which 
surrounded the roots of swamp laurel (Kalmia glauca) ; within 
the sphagnum beneath the roots of the laurel was a dark, damp 
cavity, with a capacity of possibly one peck; the runway passed 
on through this cavity to the edge of a water hole, where I was 
unable to follow it further. Specimens of Sorex richardsonii and 
Sorex personatiis were taken within a few yards of the place 
where the specimens of Neosorex palustris were obtained. 
Two males of Neosorex palustris average in measurements: 
Total length, 147 mm. ; tail vertebrae, 62 mm. ; hind foot, 19.5 
mm.; Two females average: Total length, 151 mm.; tail verte- 
"brae, 62 mm. ; hind foot, 19.5 mm.
