Remarks upon Appendicularia and Doliolum, Two Genera of the Tunicata

https://www.jstor.org/stable/108414

One of the appendicularian species found in the Bering Sea was called Appendicularia flagellum by Chamisso (1821), Oikopleura Chamissonis by Mertens (1830) and Oikopleura bifurcata by Quoy and Gaimard. Huxley id not see houses, even when keeping the animals in vessels for multiple hours. He identified appendicularia as tunicates, and notes “... so does Appendicularia typify, in the larval state of the Ascidians.” ”In young specimens the testis is greenish, and contains nothing but small pale circular cells; but in adults it assumes a deep orange red-colour“ “The animal has an ovoid or flask like body, one- fourth of an inch in length, to which is attached a long curved lanceolat tail.”
