[10] Cephalic, belonging to the head.
[11] My first introduction to the Hyaline stylet as above narrated, occurred in October 1858.
[12] Specimens of this species, I may mention, have always formed the subject of my experiments, and therefore are alone alluded to in the following remarks.
[13] Mr. Clark says, 'M. Deshayes, in his comment on Pholas, in the last edition of Lanarck, mentions the hinge as scarcely existing, and not being a veritable ligament.' How different from the fact; and I will observe, that 'if there is a genus better provided than any other of the bivalves with ligamental appendages, it is Pholas.... The Pholas is iron-bound as to ligament, which in it is far more powerful in securing the valves, than is the shell of any other group of the acephala, of similar fragility and tenuity!'

[19] This splendid work, which was published in five volumes, between the years 1802-8, contains 120 exquisite illustrations, all, with the solitary exception, unfortunately, of the Montague Sucker-Fish, accurately drawn and coloured from living specimens, procured at vast trouble by the author.
