Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 The most characteristic feature is the posterior end with its relatively enormous cirri, which are apparently large enough for an animal four times its size. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 The right hollow is larger and contains 5 great cirri of unequal size, the extreme right one being the largest. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 Segments much elongated, seven in number; I may add for comparison that each ramus of the sixth cirrus contained, in this specimen, sixteen or seventeen segments. A Monograph on the Sub-class Cirripedia With Figures of all the Species. The left hollow contains 2 cirri, also of dissimilar size. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 The contractile vacuole lies dorsal to the anal cirri and anterior to the three dorsal cirri. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 I was unable to see such a membrane in this form, but in its place there are 2 flagella-like cirri extending from the margin of the mouth-opening into the peristome, and these vibrate slowly. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 The contractile vacuole lies between the two sets of posterior cirri. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 The spines on the first three pairs of cirri, are coarsely and doubly serrated. A Monograph on the Sub-class Cirripedia With Figures of all the Species. At the posterior end an oblique hollow bears 6 unequal cirri placed side by side. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 There are no ventral cirri in front, but on the posterior ventral surface are 7 great springing cirri. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 The eighth cirrus is by itself, near the base of the largest posterior cirrus. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 These cirri, in spite of their size, are easily overlooked and more easily confused, but by using methylene blue they can be seen and counted. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 Caudal appendages shorter than, or barely exceeding in length, the pedicels of the sixth cirrus. A Monograph on the Sub-class Cirripedia With Figures of all the Species. The chief difference, however, lies in the number of anal cirri. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 Above the 5 right-side cirri, i.e., dorsal to them, but in the same depression, are 3 angular cirri. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 III in the same relative position as my eighth cirrus. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 I am positive that cilia do not occur on the ventral face of this form, and that the characteristic cirri are the sole locomotor organs.
