act as eyes. These tentacles are retractile ; and it is very interesting to watch them 

 drawn back or pushed out like the finger of a glove, and to see the curious manner in 

 which the eye speck is shot, as it were, through the tentacle attached to the slender black 

 thread which runs up its centre. 



THE genus Helix, which is universally accepted as the type of this family, is of 

 enormous extent, both in numbers and range of locality, c n \itaining more than fourteen 

 hundred species, and spread nearly over the whole earth. The common garden Snail is 

 a too familiar instance of this genus, but is so well known, that it is not figured in the 

 engraving, nor will it be described. I may, however, mention, that its depredations can, 

 in a great measure, be checked by searching for it in the winter months, and taking it 

 from the crevices in which it hides itself, or even by destroying the eggs which it lays 

 just under the surface of the soil, and which look like pellucid peas. The much-maligned 

 thrush, too, is a mighty hunter of Snails, and, in spite of its autumnal raids on the 

 fruit, does such good service in Snail-killing before the world is astir, that it ought to be 

 encouraged by the gardener, and the fruit which it eats considered as the wages p?id for 

 killing the Snails. 



OUK present example is the great EDIBLE SNAIL, which is even now largely consumed 

 in many parts of the world, and is regularly fed and fattened for that purpose. In 

 England it is not very common, but in certain localities may generally be found, .ft is
