. Bulletin - United States National Museum. Science. ASCIDIANS OF THE PHILIPPINES—VAN NAME. Ill sacs, each containing a few eggs which are apparently discharged by an orifice on a neck too short to be termed an oviduct. Testes more numerous (15 to 20) than the ovaries; they are rather large and are generally cleft into several lobes, sometimes of quite irregular outline. They are mostly arranged in a row on the left ventral region; just anterior to the intestinal loop this row bends dorsally and forward for a little distance. A few of the testes are situated on the right side along the endosty


. Bulletin - United States National Museum. Science. ASCIDIANS OF THE PHILIPPINES—VAN NAME. Ill sacs, each containing a few eggs which are apparently discharged by an orifice on a neck too short to be termed an oviduct. Testes more numerous (15 to 20) than the ovaries; they are rather large and are generally cleft into several lobes, sometimes of quite irregular outline. They are mostly arranged in a row on the left ventral region; just anterior to the intestinal loop this row bends dorsally and forward for a little distance. A few of the testes are situated on the right side along the endostyle, continuing forward the row of female gonads. In a few cases hermaphroditic gonads, each con- taining a testis and a small group of eggs, were found replacing one or two of the female gonads. The type and only specimen (No. 135) (Cat. No. G034 ) is from station D5145, off Jolo Light, 23 fathoms, coral sand and shells, February 14, 1908. This species is closely allied to S. socialis Hartmeyer, 1903 (see also Michaelsen, 1904), of the northwestern European coasts. In. my.
