Ten- tacles about 20, excluding minute ones. Ciliated groove an elongated slit or small oval opening, represented in a specimen by two orifices (fig. 84/). Alimentary canal rather small, occupying posteroventral one-third of left side. Second intestinal loop shallow, with axis pass- ing through cardiac portion of stomach, which is elongated in extended state and has about 15 longitudinal plications on surface and distinct pyloric caecum. Stomach larger than half of ventral branch of first intestinal loop. Esophagus not so long. Anal margin cut into 20-25 lobules. A single elongated gonad on each side. Testicular follicles confined to area around posterior lialf or posterior end of gonad. Remarks.—The present specimens resemble very closely Styela izuana (Oka), 1934, from Japanese waters in the general appearance of tlie body and in the number of the gonads, but diil'er from the latter in the following points: (1) The alimentary canal is larger in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; Smithsonian Institution; United States.
