Abstract
DURING the summer of 1928, while collecting Crustacea and other forms of fresh-water life in the Exeter ship canal, I had the good fortune on July 21 to find in a hand-net gathering, made midway between the Turf Hotel and Topsham ferry-boat landing, two small medusæ quite new to me. These I preserved, and later sent them to Mr. Edward T. Browne, who identified them as Craspedacusta Sowerbii. A short time later, Mr. Browne kindly sent me a tow-net, but the great difficulty then was to get a boat. However, I succeeded in obtaining more than a hundred specimens, ranging from early stages up to the fully grown adult. The medusa was present in the canal up to Sept. 8, when some early stages were taken. During the past summer (1929) I have been more successful, and have been able to get a suitable punt whenever I wanted one.
