                                Anatomical studies of a marine gastropod named by the author Jasonilla McLeayiana [a variety of Lamellaria?] specimens collected “between Port Jackson and the Isle of Pines” eg between Sydney, Australia and New Caledonia in the Pacific Ocean. 
Figures 1-6 showing: a magnified study of the animal taken out of its shell (figure 1); views of the shell at natural size and under magnification (figures 2-4); and studies of the radula (figures 5-6).
 
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.
