Chyhis cells. — In several longitudinally sectioned specimens these cells were found in somites XI to XIII. The intestine in these somites is differentiated into a crop consisting of a layer of chylus cells separated in the usual manner by epi- thelial cells and interstitial cells. The arrangement is a most regular one. Seen in a thin median _ section passing between the dorsal vessel and the ventral ganglion, and in the longitudinal diameter of the body, we find that the chylus cells are cut through perpendicularly and that each such cell is separated by about two epithelial cells and by one or two interstitial cells. In other words, the chylus cells are placed at regular intervals, the same distance being kept between each two of them in all the three somites. The canal in this species is lined by a distinct membrane which is ciliated along its.
