Fig. xi. The purple-marking whelke. From Mount s-Bay and 
Loo. The juice which marks is in a feparate bag, of a yellowifh 
green when firft drawn upon linen, grows a little ruddy after- 
wards, till it comes to a faint purple ; when dry, and the linen 
wafhed, it is of a good purple, and rather betters by age and 
frequent wafhing.

exigua , purpurafcens Jlriis minimis tranfuerfis , tribus maculis fufcis

It is very curious to obferve how this ihell-fifh proceeds to its 
maturity : it is here in its infancy, but it narrows this wide open- 
ing, and gradually buries the voluta of its apex, as it contracts its 
aperture, till it arrives at the ftate of a perfect courie, when it 
throws all the after-thickning of its fhelly-increafe from its iides 
round to its back, where the joining of the two teftaceous apophyfes 
may be plainly perceived h .
