A Land Planarian. 
499 
is nearly twice the diameter of the others. No peculiarities of this 
nature have thus far been noted among land planarians although 
vonGraff (’99) in his monograph briefly discusses certain varia¬ 
tions in other organs. 
It is of interest to extend the range of our land planarians and 
those engaged in work in Invertebrate Zoology should be able to 
find them, particularly on summer mornings after a rain, under 
partially decayed boards on lawns, in orchards, etc., in company 
with young snails which they superficially resemble. 
R. sylvaticus was collected by Leidy in 1851-58 and the material 
evidently lost. Since then the writer has taken it at Gambier 
and Urbana, O., and at Meadville, Pa. It is about 10 mm. long, 
grayish black with two darker longitudinal lines dorsally. R. 
alrocyaneus is about 20 mm. long when in a living condition, and 
uniformally dark blue in color. It has only been found in Gambier, 
O. When collected, specimens should be killed almost immediately 
with some hot “killing fluid” inasmuch as they die and disintegrate 
very quickly. They may however, be kept alive for several hours 
in a small clean vial provided there is also placed within a piece 
of a partially decayed leaf.
