. A textbook of invertebrate morphology [microform]. Invertebrates; Morphology (Animals); Invertébrés; Morphologie (Animaux). em. ma Fig. 290.—^, Salpa mueronata, the SEXUAii Form, and B, Salpa democro' tica, THE Non-Sexual Form of Salpa democratica'ViucronaUi (after Claus). c, cl = cloaca. in = brunchial pore (mouth). cp — ciliated pit. ma = test. em = embryo. n = uerve-guugliou. en = eudostyle. nu = nucleus. h — heart. at = 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 develop- ment of this ovum the non-sexual form (5) is produced, which is characterized not only by its general form, but also by the possession of a stolon (5^) arising from the branchial sac just.
