Abstract
YESTERDAY my assistant, Mr. G. Pyman, found several Cheirocephalus diaphanus swimming in a flooded ditch on Eton Wick Common. The sunlight shining on the beautiful green bodies of the males made a very striking effect. We were able to catch about twenty specimens of both sexes. I had never seen this phyllopod alive before, and, so far as I know, it has never been recorded previously from this district. The females, of brownish-purple colour, all have full egg-cases attached to their abdomens. I put several individuals into different aquaria, and was much annoyed to find that they fell victims to various enemies during the night. A Dytiscus beetle, the presence of which had been forgotten, accounted for four, and four more were apparently devoured by insignificant fresh-water snails. Those, however, that were placed in a tank by themselves are alive and well, and feed on the green algæ supplied to them. The males are about 11/2 inches long, the females rather smaller.
