Big-mouthed fish, worms, spiders, anemones, sea-cucumbers, polyzoa, prawns, little fish like sardines, one spiky fish like nothing on earth, starfish and octopus, limpets with jointed shells, sponges, ascidians; isopods, and all kinds of sea lice. Enough to keep Lillie busy for weeks.
The main interest of the question of course lies in its bearing on the long-disputed relations between plants and animals; for, since neither locomotion nor irritability is peculiar to animals; since many insectivorous plants habitually digest solid food; since cellulose, that most characteristic of vegetable products, is practically identical with the tunicin of Ascidians, it becomes of the greatest interest to know whether the chlorophyl of animals preserves its ordinary vegetable function of effecting or aiding the decomposition of carbonic anhydride and the synthetic production of starch.
'There is a class of animals called Ascidians, which possess a heart and a circulation, and up to the year 1824 no one would have dreamt of questioning the propriety of the deduction, that these creatures have a circulation in one definite and invariable direction; nor would any one have thought it worth while to verify the point.
This is a member of that curious family of Ascidians, which forever trembles in the balance between the higher backboned animals and the lower division, where are classified the humbler insects, crabs, and snails.
Brightly colored starfishes, beautiful sea-urchins, strange stationary ascidians, and flower-like sea-anemones, quaint sea-horses, and filmy, fragile jellyfishes and their multiform kin all seem novel and wonderful as one sees them in their native element.

Some of these animals have eye-specks on the edge of the mantle; but this is not a constant feature. This class of Acephala includes all the Oysters, Clams, Mussels, and the like. When named with reference to their double shells, they are called Bivalves; and with them are associated a host of less conspicuous animals, known as Ascidians, Brachiopods, and Bryozoa.
The Quadrumana and all the higher mammals are probably derived from an ancient marsupial animal, and this through a long line of diversified forms, from some amphibian-like creature, and this again from some fish-like animal. This animal seems to have been more like the larvae of the existing marine Ascidians than any other known form.
In the case of some of the long-drawn-out forms of clustered ascidians and the like, the delicacy of manipulation required to make successful preservations raises the method as practised at Naples almost to the level of a fine art.
Now it is a mysterious fact that in the higher and now terrestrial Vertebrata, as well as in other classes, many normal and abnormal processes have one or more whole weeks as their periods; this would be rendered intelligible if the Vertebrata are descended from an animal allied to the existing tidal Ascidians.
