Description
Anatomical studies of a marine nudibranch sea snail of the family Phylliroidae classified by the author as Phylliroe bucephala. Specimens collected in the Pacific Ocean around Lord Howe’s Island and Norfolk Island near Australia.
Figures 8-9 showing microscope views: of the integument (skin surface) of the animal including muscle, nerves and pigment spots (figure 7); and of the investing membrane of the ovary with pigment cells (figure 8).
These specimens were described by the author aboard HMSV Torch, the tender to HMS Herald in December 1854 as the vessels were engaged in survey work in the South Pacific. The author, John Denis Macdonald was at this time assistant surgeon on the Torch.
