Collected here:
Dugesia tigrina (Girard, 1850) | Apr 8, 1941 | | | Very numerous specimens under stones, all of the spotted pattern, but with varying amounts of spottiness, and different tones of brown. Ten individuals in more than one hundred were sexual. These were rather small (6-8 mm long). |
Dugesia dorotocephala (Woodworth, 1897) | Apr 8, 1941 | | | under stones, one immature specimen of this species with more than one hundred Dugesia tigrina. Dr. A.E. Woodhead informed me that in this place the species has repeatedly been collected in larger numbers. |
