The right ventral appendage from the ventral side; a little reduced, ab abdominal pore. Fig, 28. The same from the dorsal side. part, where it passes over the medial edge on the ventral side, and here it ends in the shape of an 5'; thus the whole slit is formed like a cork-screw. Immediately be- hind the hole the edges can only with difficulty be separated on account of the stiffness of the skeleton; but in the terminal part the slit is easily opened on account of the thinness of the skeleton, which is here like a thin, convoluted shaving, which may to a certain degree be unrolled. The inner, tubular hollow of the terminal part, as well as its opening at the point is completely stuffed with secretion, which also fills the hole at the base as well as the nooks between the appendix, the base of the fin, and the body. As to the skeleton, I think it pretty sure that in the shaft it is as in Chimmra; as we find a rather mov- able joint before the hole , the surroundings of which seem to be quite as in C/iiiitcrra, we may be justified in supposing the basale to end here; somewhat out on the shaft we find another, little movable joint; accordingly the piece bt is found between these two points; on the ventral side the distal border of this piece is distinctly marked by the cessation of the inmost part of the muscular mass of the glandular bag (the calf ); the other part of the skeleton then must be the appendix-stem; this seems here to be formed like a convoluted leaf, in which no separation into branches is found; such branches, no doubt, would be discernible through the membranous skin, if lines of separation really existed (the only place where such a line of separation might perhaps be found, is along the lateral edge of
