. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. 246 CHILD. [VOL. I. that the notch in the right edge which appears to separate a from b is really in a, for the dorsal furrow reaches the edge anterior to it, and the two pores are equidistant from this furrow. At the left side of a b there are two complete sets of organs opening to the exterior through a common pore which lies in the middle of the undivided edge of a b. In the region of the ovaries the furrows are normal, and accordingly the ovaries are nearly the normal distance apart. The left end of a is short, so that the full normal distance between the ovaries is not attained. Since the. FIG. 22. furrows do not quite reach the edge, it is undivided, and presents the relations of a single rather long proglottid. As might be expected, only one pore is present, though rather larger than normal, and into this the two oviducts and two vasa deferentia open, for the two sets of ducts approach each other as they reach the undivided region. The segment c, of about normal length, and the segment d, which is of less than the normal length, except at the edge, are partially separated by two partial furrows which correspond very closely in position and extent on the two surfaces. The segment c is nearly the same length throughout, but d is longer at the.
