April, 1915.] 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. syhaticus was collected by Leidy in 1851-58 and the material 

 evidently lost. Since then the writer has taken it at Gambler 

 and Urbana, O., and at Meadville, Pa. It is about 10 mm. long, 

 grayish black with two darker longitudinal lines dorsally. R. 

 atrocyaneus is about 20 mm. long when in a living condition, and 

 uniformally dark blue in color. It has only been found in Gambler, 

 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.
