Lateral views, ft, fatty invest- ment of swimbladder;^, gas-gland; oy, ovary; rm, rete mirabile; rsb, regressed swimbladder. (a, X4"5; a', x 11-5; b, x 17-5.)

In this individual there is a regressed swimbladder lying above the ovaries. Fatty tissue invests the organ and is continued forwards and backwards into rod-like prolongations. The anterior one extends to the front of the ovary, while the backward one, which is more slender and tapering, ends rather more than half-way down the body-cavity. The length of the swimbladder is about 4-5 mm. Entering the posterior end is an artery and vein supplying a club-shaped rete mirabila which is about 1-5 mm. in length. In the middle of the bladder is a small gas-gland, o-8 mm. in length, which all but obliterates the lumen. Forward of the gland there is no lumen, but merely a ' solid' mass of connective tissue.
