30 PEKIAVINKLE. 



He is called by naturalists T. litioreus, from littoralh — belong- 

 ing to the shore, and often eaten by boys and girls with great 

 relish; but he is not very digestible, and sometimes occasions 

 dangerous disorders. The Swedish peasants believe that when 

 the Periwinkle crawls high upon the rocks, a storm is brewing 

 from the south; but Linnaeus quotes a Norwegian autlior to 

 shew that according to popular belief, it foretells the approach 

 of a land wind with a calm on shore. Man may learn much 

 of elemental changes from an observation of the movements 

 and habits of all living creatures, wliich are instructed by 

 God to provide for tlieir safety and wants, and often perceive, 

 long before man himself d<x.'s, tlie indications of calm and 

 tempest, rain and drought, etc. liut our little Turlo, what 

 of him? will you boil him, and pick out his curled-up form 

 with a pin.^ or let him go crawling about the rocks, feedhig 

 upon the delicate earlier growth of marine vegetation? In 

 the former case, you will have to reject the little kind of 

 horny scale attached to his foot, which forms, when he retires 

 into his habitation, a closcly-iitting door to make all snug. 



Several sjiccies of this genus are found on our shores; one 

 of those is the Turbo riulis, or Ked Turbo, which has a very 

 thick ])criwinkle-like shell, about three-quarters of an inch 

 long; the colour is dull red, fawn, or drab. 



Of the foreign Turlince, sometimes called Turbini Shells, 

 we will now introduce two or three species, which will be 

 found on Plate III. Pig. 3 is the Marbled Turbo, (jT. luarmo- 

 ratuit,] from the Latin mannor — marble; a large handsome shell 

 well known to conchologists, and a native of the Indian seas. 

 Pig. 4 is the Twisted Turbo, {2\ torquatiis ;) this shell, when 

 deprived of its outer coat or layer, is beautifully nacreous, or 

 if we may so speak, mother-of-pearlj'. The specimens Mhich 

 have reached England were brought from King George's Sound. 

 Pig. 5 is called Cook's Turbo, {2\ Cookii:) this is a handsome 

 South Sea shell, oftentimes of large size. It has been found 

 in great numbers on the coast of !Xew Zealand. 



On Plate IV, we have placed two very curiously formed 

 and marked shells, called AVentletraps, also belonging to the 

 family Turhinidcd. The scientific name is Scalar ia, from the 

 Latin scala — a ladder, which the ribbed shells are supposed 

 to resemble. Of this genus there are about eighty dislinci;
