. A textbook of invertebrate morphology [microform]. Invertebrates; Morphology (Animals); Invertébrés; Morphologie (Animaux). em. ma Fig. 290.—^, Salpa mucronata, the sexttal Potim, and B, Salpa demoera- tica, THE Non-Sexual Form of Salpa democratica-mitcronata (after Claus). c, cl = cloaca. ni = brauchial pore (mouth). cp — ciliated pit. ma = test. em = embryo. n = nerve-gauglion. en = eudostyle. nu — uucleiis, h — heart. si = stolon. single ovum. This when fertilized (em) is passed into the atrial cavity, the follicle-cells with which it is surrounded forming an adhesion to the wall of the cavity, and later modifying to form a structure recalling the placenta of the Mammalian Vertebrates by which nourishment is conveyed from the parent to the embryo. As the result of the devel()]i- ment of this ovum the non-sexual form {B) is produced, which is characterized not only by its general form, but also by the possession of a stolon {st) arising from the branchial sac iust.
