The color areas should be outlined with pencil in the field, 

 while the animal is under observation, and after it has been 

 identified, the areas should be colored with crayons or water 

 colors. Egg and larval diagrams should be made in a similar 

 way if the specimens are observed in the field, but otherwise 

 notes as to color, number, size and similar data may be 

 obtained from the instructor or from the texts. 



The figures are so designed as to admit of the introduction 

 of such laboratory characters as scalation and costal 

 grooves, when needed. 



In addition to outlining the color areas, such other items as 

 are observed or given by the instructor should be written in 

 the field. Notes on general distribution, migration and 

 hibernation and other topics not considered or recorded 

 afield, should be obtained from the texts. In determining 

 the size use the ruler on the back cover, except in the mammal 

 studies where well-known forms may be chosen as standards. 



In planning this booklet the authors have selected only 

 such features as have been fully tested through ten years of 

 experience in teaching university classes in field study.
