Merriam I have examined the series of wood rats of this form, from 
many points in the lower Mississippi Valley, in the Department of 
agriculture collection; this series shows only a small range of color 
variation among the adults, which can be distinguished from the 
smaller, grayish, and yellowish true JV. floridana.

Type locality. Georgia (probably the Leconte jdantation near 
Riceboro). 
The little liar vest mouse is found locally throughout eastern 
Georgia and northern Florida. Mr. Brown took only one example 
on his trip, an adult female that he caught at Pinetucky. I have 
taken it myself only at Gainesville, Florida. Here, in a large stretch 
of old fields partly grown up to hickory and deciduous oaks, and 
where the ground was covered in places by bunches of broom grass, 
I found it very common. 1 trapped a number, but hot weather and 
ants destroyed all but eight. These specimens are wholly referable 
to true It. lecontii , being neither darker in color nor smaller than 
examples of that form from Georgia or North Carolina. The four 
larger adults range in size between No. 7,055, total length, 127 ; 
tail vertebrae, 60;' hind foot, 15; and No. 7,058, total length, 131; 
tail vertebrae, 58 ; hind foot, 15. 
Reithrodontomys lecontii dickinsoni (Rhoads). 
Heithrodontomys humilis dickinsoni Rhoads, Amer. nat., June,

Type locality. Willow Oak, Pasco County, Florida. 
It is with much hesitation that I include this doubtful Florida race 
of the little harvest mouse. It is still known only by the two 
specimens Mr. Rhoads had at the time he named the subspecies. 
Both these are now before me, having been kindly lent by Mr. 
Rhoads. The type is certainly of a very dark sooty color and can 
not be matched exactly in this respect by any I have seen from
