The fist I thus describe: The open of the shell is pretty round, the second turn or wreath is very large for the proportion, and the rest of the wreaths, about the number of six, are still lessen'd to a point, This Turben or Conical figure is well neare a quarter of an inch; the colour of the shell is duskish, yet when the shrunk animall gives leave, you may see day through it, and then it is of a yellowish colour. These shells are extreame brittle and tender, so that I cannot send them in a Letter: You may guess at the figure, if I tell you, they are some-thing like those of Aldrovandus de Testaccis, markt p. 359. Turbinum levium,

Of the second sort l fend you inclosed at a venture halfe a dozen; (you see, in that I can so plentifully repair the loss of the former, that they are not very rare; (they seem to be much stronger and thicker shell'd; they are well near halt as long again as the other, and as slender; they have the exact figure of Oat-corn, being as it were pointed at both ends, and the middle a little swelled. The open of the shell is not exactly round there being a peculiar Sinus in the lower part thereof. I think, you may number about 10. Spires, having their turn from the right hand to the left. The colour of the Shell is of a dark and reddish brown.

There are two sorts of this make described, and with their respective Cutts, in Fabius Columna; but ours agree not with them in any thing more than the odd Turn: though 'tis true, that the other, the third there described, and call'd by him Cochlea Terrestris turbinata et striata, is very frequent in the road 'twixt Canterbury and Dover, and likewise in some wooddy parts of the Woles in Lincolnshire. There are odd differences in this very Snaile very remarkable, as its having but one pair of horns (if I mistake not,) as also a hard shelly cover; its manner of wearing that cover &c. which I leave to another opportunity and place.

And to return to our two now described Snailes, they, when they creep, lift up the point of their shells towads a perpendicular, and exert with part of their body two pair of horns, as most of their kind doe.

In March they are still to he found in paires, Aristotle affirmes,all
