him Dr. Merriam writes as follows: ‘Unfortunately the skull is 
broken at the junction of the rostrum with the cranium proper, and 
as it has not been removed from the skin I am still in ignorance of 
the skull characters. The teeth, however, leave little doubt that 
the species is Sorex longtrostris, of which we already have specimens 
from Indiana. Its occurrence in a tamarack swamp in extreme 
northern Illinois, however, is surprising.” 
The following are my own data on the specimen, taken from my 
note-book. Length, 76 mm. (3in.). Tail, 31 mm. (1.2 in.). Hind 
foot, 11 mm. (.4 in.). Color (described after putting in alcohol but, 
I think, before any noticeable change had taken place): The back 
is sepia with clove-brown-tipped hairs mingled. These are more 
abundant toward the rump. The color is lighter below, varying 
through drab to drab-gray, and being still paler on the throat 
and chin. The tail is bicolor—clove-brown above, drab-gray 
below. The feet are drab-gray, but the palms and soles are 
darker. 
I have ventured to call the species Bachman’s shrew, rather 
than to translate the Latin specific name, longzrostris (long-nosed), 
since in fact the muzzle of this species is broader and shorter than 
in our other species. 
SHORT-TAILED SHREW. 
Blarina brevicauda (Say). 
Sorex brevicaudus Say, Long’s Exped. Rocky Mts., I., 1823, p. 164. 
The typical form of the short-tailed shrew is found from western 
Nebraska and Manitoba to the Atlantic. On the south it inter- 
grades with the subspecies carolinensis, which is found to the Gulf. 
I have referred all my specimens from the northern half of Illinois 
to the typical form, though it is possible that some of them are, 
rather, transitional forms. A few specimens taken in the southern- 
most county of the state, I have regarded as the above subspecies. 
The average size for brevicauda given by Merriam* is about 125 
mm. (4.92 in.). 
The following table shows the measurements of 44 specimens 
from the northern half of the state.
