The edges of this umbrella, as well as the mouth, or the suckers, more or less prolonged into pedicles, which take its place, in the middle of the lower surface, are furnished with tentacles of very different form and size. These different degrees of complication have given rise to very numerous divisions. The Arachnodermata form the second class of M.
Page 8 - ... the greatest tenacity to whatever body they embrace. They swim with the head backwards, and crawl with the head beneath and the body above. Surrounded by the arms or fleshy appendages mentioned above is the mouth, armed with two stout horny jaws resembling the beak of a parrot ; the tongue bristles with horny points ; the oesophagus swells into a crop, and then communicates with a gizzard as fleshy as that of a bird, to which succeeds a third membranous and spiral stomach, which receives the...
Page 20 - Pneumodcrmon ; but their body is terminated by a tail, which is twisted spirally (" contourue'e en spirale"), and is lodged in a very delicate shell, of one whorl and a half, umbilicated on one side and flattened on the other.

The vent is at the opposite end of the body : the intestine is very long, being folded several times, and near the vent are two ramified organs for the purpose of respiration. The eggs are contained in an oblong sac which has its opening near the base of the proboscis. The animal is described as living deep in the sand, and projecting its proboscis till it arrives...
Page 87 - ... have the sexes united in the same individual. The shells of this order are always without an operculum, very wide in the opening (some of them may be said to be almost all aperture), and many of them have shells without any turbination, so that they cover the animal, and especially its branchim, like a shield.
Page 468 - ... shorter, narrower and annulated, with crowded lateral filamentary appendages branching from the base. Ovaries long and filiform. Head, neck, and ovaries straw-colored ; thorax, abdomen, and appendages black. In the Regne Animal of Cuvier, it says, there is in the Mediterranean a species, Penella filosa, seven or eight inches long, which penetrates into the flesh of the Sword-fish, the Tunny, and the Sunfish, and torments them horribly. Similar cases of the wonderful bounty of nature are frequent,...
