The upper, wide opening of the duct is attached by elastic, peritoneal lamellae to the hinder margin of the left lung; the middle portion of the duct is glandular and thick-walled, for the deposition of the albumen; it is connected by a short, constricted " isthmus " (where the shell-membrane is formed) with a dilated " uterus " in which the egg receives its calcareous shell and eventual pigmentation.
Lankester in the ninth edition of this work attributed it to the pressure of the shell and visceral hump towards the right side.
Neither the rotation of the shell as a whole nor its helicoid spiral coiling is the immediate cause of the torsion of the body in the individual, for the direction of the torsion is indicated in the segmentation of the ovum, in which there is a complete A B From Lankester's Treatise on Zoology.
In some forms the coiling disappears in the adult, leaving the shell simply conical as in Patellidae, Fissurellidae, &c., and in some cases the shell is coiled in one plane, e.g.
De- nt generation of the shell occurs in some members of the order.
Trochus, shell umbilicated, spire pointed and prominent, British.
After I had learned a great many interesting things about the life and habits of the children of the sea--how in the midst of dashing waves the little polyps build the beautiful coral isles of the Pacific, and the foraminifera have made the chalk-hills of many a land--my teacher read me "The Chambered Nautilus," and showed me that the shell-building process of the mollusks is symbolical of the development of the mind.

Not far from the scene of this conflict stands Balquhain Castle, a seat of the Leslies, now a mere shell, which was occupied by Queen Mary in September 1562 before the fight at Corrichie between her forces, led by the earl of Moray, and those of the earl of Huntly.
The shell heaps found on the coasts and elsewhere dispose of the theory that New Zealand was uninhabited or practically so six centuries back.
A nearer view will reveal the rich chestnut of the mantle and upper wing-coverts, and the combination of colours thus exhibited suggests the term "tortoise-shell" often applied to it - the quill-feathers being mostly of a dark brown and its lower parts pure white.
It has a royal shell factory, calico-printing mills, lignite mines, stone quarries and pottery and tobacco factories.
There are large prehistoric shell-mounds at Indian Hill, about 20 m.
In John Houghton's Collections on Husbandry and Trade, a periodical work begun in 1681, there is one of the earliest notices of turnips being eaten by sheep:" Some in Essex have their fallow after turnips, which feed their sheep in winter, by which means the turnips are scooped, and so made capable to hold dews and rain water, which, by corrupting,; _ mbibes the nitre of the air, and when the shell breaks it runs about and fertilizes.
Movement flexure is also produced by the coiling of the visceral sac and shell; primitively the latter was bowl-shaped; but the ventral flexure, which brings together the two extremities of the digestive tube, gives the visceral sac the outline of a more or less acute cone.
The shell is represented as fixed, while the head and foot rotate from left to right.
In reality the head and foot are fixed and the shell rotates from right to left.
In a dextral Gastropod the shell is coiled in a right-handed spiral from apex to mouth, and the spiral also projects to the right of the median plane of the animal.
Shell spiral; mantle and shell with an anterior fissure; two ctenidia; a horny operculum.
Spire of shell much reduced; two bipectinate ctenidia, the right being the smaller; no operculum.
Puncturella, mantle and shell with a foramen in front of the apex, British.
Shell conical, symmetrical, without slit or perforation.
Shell spirally coiled; a single ctenidium; eyes perforated; a horny operculum; lobes between the tentacles.
When the shell is sinistral the asymmetry of the organs is usually reversed, and there is a complete situs inversus viscerum, the direction of the spiral of the shell corresponding to the position of the organs of the body.
But there are forms in which the involution is " hyperstrophic," that is to say, the turns of the spire projecting but slightly, the spire, after flattening out gradually, finally becomes re-entrant and transformed into a false umbilicus; at the same time that part which corresponds to the umbilicus of forms with a normal coil projects and constitutes a false spire; the coil thus appears to be sinistral, although the asymmetry remains dextral, and the coil of the operculum (always the opposite to that of the shell) sinistral (e.g.
He referred also to the nautiloid shell of the larva falling to one side.
Rvg, Primarily right(subsequently the shell the spire comes to project on the right side, which was originally the left.
Burr.- p T 9 pl.y ped.g: reversal of the cleavage planes in sinistral as compared with dextral forms. The facts, however, strongly suggest that the original cause of the torsion was the weight of the exogastric shell and visceral hump, which in an animal creeping on its ventral surface necessarily fell over to one side.
It is not certain that the projection of the spire to the originally left side of the shell has anything to do with the falling over of the shell to that side.
