The gas-gland lies immediately in front of the rete and is partly or entirely divided into two left and right halves. A layer of fatty tissue invests the swimbladder walls of the 26-5 and 32-5 mm. fishes. The de- position of the fat takes place between the peritoneal layer surrounding the sac and the tunica externa, transverse sections through the swimbladder of the 36 mm. fish revealing that the space between these two layers is filled with loose reticular connective tissue (see also p. 67). The resorbent capillary circulation has not been closely investigated. However, there is an artery running forward by the
