earth-worm debouch into the alimentary canal in advance of the gizzard, but posteriorly to it in Urochtæa and some other genera.[1] The two posterior pairs are formed by lamellæ, which according to Claparède, are diverticula from the œsophagus.[2] These lamellœ are coated with a pulpy cellular layer, with the outer cells lying free in infinite numbers. If one of these glands is punctured and squeezed, a quantity of white pulpy matter exudes, consisting of these free cells. They are minute, and vary in diameter from 2 to 6 µ. They contain in their centres a little excessively fine granular matter; but they look so like oil globules that Claparède and others at first treated them with ether. This produces no effect; but they are quickly dissolved with effervescence in acetic acid, and when oxalate of ammonia is added to the solution a white precipitate is thrown down. We may therefore conclude that they contain carbonate of lime. If the cells
