Conchology. 5 



and have perhaps heard a surly, snappish, peevish 

 person called a crusty fellow; they will now 

 understand what is meant by a crustacean and 

 crustaceology, that part of Zoology which treats of 

 crustaceous animals. They constitute quite a large 

 family, these ologies, and have a strange way of 

 twisting themselves about, and exchanging limbs 

 and features, so that one is puzzled at times to tell 

 which is which. But here we have fixed two of 

 them, called Testaceology and Crustaceology, twin 

 brothers, and very much alike in their character- 

 istics. Let us have a good look at them, so that 

 we may know them again if we should lose sight of 

 them for awhile. Now we will spell over the name 

 of the first— 



CONCHOLOGY. 



Why, it is changed already ! Has this science of 

 shells then another name? Yes, and this is it, 

 pronounced kong-Jcol-o-gy, and derived from the 

 Latin concha, which means properly a shell -fish 

 with two shells, joined by a hinge, as the oyster, 

 the cockle, etc. This present volume then is a 

 work on Concliology, the subject of it is Conchiferous, 

 and whoever studies it will be doing something 

 towards becoming a Conchologist.
