round and fpread out a little $ the inner ftrait, like white 
Marble, its inner edge toothed, and fpread outward almoft. 
as far as the Navle of the fhell 3 from whence I have 
nam 'd it. The Turban is low and almoft flat. It maketh 
fcarce more than two rounds, which therefore immediately 
run from great to fmall. On the outiide 'tis ruged with 
tranfverfe wrinkles, and fpeckled with red and black fpots 
upon white. 
The toothed Lips of both thefe laft Shells, moft pro- 
bably, ferve as Joynts to hold their lids, fo much the more 
clofe and fteady. 
The FORE-WHIRED SNAIL. Cochlea Turbine antico. 
This is no where defcribed. 'Tis fmooth, of an afh-colour. 
The outer Lip is fpread a little backward; and toothed with- 
in : as is alfo the edge of the inner Lip. Both the corners of 
the Mouth are placed on the circumference of the utmoft 
round. Whereby,contrary to all other fhells I ever yet faw, 
it hath the Turban or Whirle made before. Tis much de- 
preffed, confiding of five flat rounds. The aflertion of 
( a) Hift. Ariftotle, (a) That the Turban always ftands behind, is here

The FL AT-WHIRLE. This Snail is a perfect Helix, all

Cochid s de -^ r * tyfi €r W defcribeth three forts. Of which he ob-

or the like, into their Mouths, they yield a Crimfon 
liquor. 
(O'.ibid. p. 1. The fame Author (c) hath obferved fome particulars of 
the parts of Snails $ as their Horns, Eyes, (as he fuppofeth 
them) Teeth, Anm, Lungs, milkly Veins ( which are all they 
have ) parts of Generation, ckc. Which laft, faith he, are fo 
like, as to make it feem very probable, That they are Her- 
maphrodites. In the time of Coition, they ftrike a fort of 
fmall teftaceous Needles (Spicula teftacea) into one an 
others Necks. For what caufe, or in what manner, he could
