During the summer session of the University of Montana Biological Station, we found what is believed to be a new hydra. It was taken in large numbers from Echo Lake, Flathead County, Montana. It has never been found in any of the other numerous streams or lakes in this vicinity, and so far as is known no other hydra has ever been collected in the state.
