23. 231, 1869) refers to these Middleboro specimens and adds, “There 
are also several specimens in the Museum of Comparative Zoology 
from localities near Cambridge.” Upon examination of the latter I 
find they were taken at Hudson, a town nearly twenty-live miles 
west of Cambridge, on the borders of the higher country of Worces¬ 
ter County, where indications of a Canadian tinge to the fauna are 
to be expected. Since Professor Baird wrote, the s}3ecies has been ■ 
found to occur generally throughout the Canadian portions of New 
England and New York, but until recently nothing further had 
come to light as to its occurrence in southern New England. 
In the light of these facts the Middleboro locality appeared to be 
occu|3ied by an isolated colony, and the interest attaching to it was 
increased by the recent discovery in southern New Jersey (Stone, 
Amer. Nat., 27, }3. 54) of an Evotomys very closely related to E. 
gapperi. This led me to attemj3t to investigate more fully the 
details of the distribution of the species in southern New England, 
and the facts already obtained seem sufficiently interesting to be 
made public. 
I have tra232>ed for Evotomys in a number of })laces in eastern 
Massachusetts. Selecting } 3 oints at such distances from each other 
that no area beyond a certain size should be left untouched by them, 
at each locality I have searched the surrounding country for ground 
that seemed suitable for the occurrence of the s}3ecies, and when it 
was found I have tra}3]3ed until successful, or until failure prompted 
me to look for better ground elsewhere in the vicinity. 
As a result, I have taken it in Ipswich and Methuen in Essex 
County; in Tyngsboro, Winchester, and Weston, in Middlesex 
County, and I have Mr. William Brewster’s permission to mention 
the cajoture of one by him in Concord in the same.county. I have 
taken it in Sharon and Bellingham in Norfolk County. I have 
caught it in Hingham in Plymouth County, and Professor Baird’s 
old record for Middleboro and a more recent one by Mr. Outram 
Bangs (Proc. Biol. Soc. Wash., 9, p. 99-100) of its presence near 
Wareliam, furnish additional localities in this county. There is a 
specimen in the collection of the Boston Society of Natural History 
from Seekonk in Bristol County, and I have taken others at New 
Bedford in the same county. In Barnstable County, I have captured 
it, myself, at Wood’s Hole, and I have specimens collected under my 
direction in the summer of 1894, by Mr. W. W. Brown, Jr., at two 
localities in Dennis.
