. Bulletin of the United States Fish Commission. Fisheries -- United States; Fish-culture -- United States. 3i6 BULLETIN OF THE BUREAU OF FISHERIES. t pap Head (except the eyes) small, rather elongate above and below. Funnel large, with a strong ven- tral flexion; membranous, thin, much wrinkled in the preserved specimens; true valve lacking, its place taken by a thickened fold or pseudo-valve on the dorsal wall just in advance of the median pad of the funnel organ. Funnel organ highly complicated, comprising three distinct components, as follows: A large, rounded ovate, flattened pad on each ventro-lateral wall; between them a large, conspicuous, median, liver-shaped pad, its convex outline directed forward; from its center rises a long papilla, robust at the base, but tapering and terminated by the anal aperture; lateral lobes of this pad broad and rounded, each of these also giving rise near its center to a rather large, soft, bluntish papilla, which appears to terminate blindly in a rounded, finger-like extremity. The general arrangement of the entire apparatus is represented in the annexed diagram (text fig. 17), as well as in figures 5-6 of plate Liv. Eyes relatively enormous, globular, sessile, nearly approaching in the median line below; open- ings small. Sessile arms moderately short, about one-fourth as long as the body, unequal, their order 4, 3, 2, i; rather slender and delicate, each bordered by a broad, extremely delicate, hyaline membrane strength- ened by numerous fairly slender, trabeculse having their origin near the base of the suckers (pi. XLVi, fig. i). Suckers small, subsphcrical, obliquely placed on very short pedicels in two regularly alternating rows of about 20 to 25 each; homy rings well developed, but delicate and smooth (text fig. 18). Tentacles long, somewhat stouter at the base than the sessile arms and about twice as long; inner surface flattened and with a median groove, on either side of which appears a row of minute fla
