The minor subdivisions of both animal and plant kingdoms are 

 very numerous and are known as Families, Genera, Species and 

 Varieties. The scientific name of any animal or plant consists 

 merely of the name of the genus and species to which it belongs. 

 This method of naming animals and plants is due to Linnaeus 

 (1707-1/78) and is known as binomial nomenclature. 



Inspect the specimens in the Museum, Herbarium and Vivarium, 

 and become familiar with as many as possible of the classes named 

 above. Enter in your laboratory notes in the following manner 

 the scientific name (copied from the labels of specimens on exhi- 

 bition) of some one member of each class and phylum of the animal 

 kingdom, so far as represented in the exhibits :
