EL Karlstuen 1956 Buffo lunea Richmond (cont.) Feb. 7 edge of pond where shallow water (few to 10-12") fails to cover sedge and grasses. Here seemed to be a toad every 3-4 feet on the average. Two pairs in complexus. To count the toads and check for dipped toes I picked them up and then tossed them out toward deeper water of pond. Returning to this area of concentration after an absence of 3-4 minutes I would find again as many toads in the shallows (where they couldn't have returned). The animals habit of diving for the bottom when disturbed means almost every other toad is not picked up when one dives a light into an area. There could easily have been 200 adults in pond A alone. I did not see eggs where complexing pairs found, although 1xyla cluster (only one found) in pond A had embryos in free-swimming stage. Toad eggs probably available, but it would appear that Buffo breeding is just getting underway. Sexual dimorphism checked when pairs found. O's are more greenish on the average whereas F's tend toward grayish g.c. and possibly more large spots or reticulative. O's smoother skinned and have greater degree webbing trail feet. Some pattern and sex dichromism about 3/4 pairs looked at, but it couldn't be relied upon in all cases. Three toads, 1 F and 2 O's removed
