III. MOVEMENT. 



1. Is the animal free-moving or sedentary? (a) If free moving 

 is it passively carried by winds or currents, or does it move active- 

 ly? Do the organs of locomotion indicate that it is fitted for swim- 

 ming, walking, running, creeping, leaping, burrowing, or flying? 

 Draw one or more of the locomotor organs, (b) If sedentary is it 

 free or attached ? Show by drawings the means of attachment. Are 

 there any rudiments of locomotor organs? Are sedentary animals 

 descended from free-moving ones, or vice verso,? 



2. Does this species undergo periodical migrations? If so des- 

 cribe them. 



3. In the specimen assigned you by what means is the dispersal 



of the species secured, and what are the barriers to such dispersal ?

IV. GEOGRAPHICAL DISTRIBUTION. 



i. To what Zoogeographical Region of the earth is the animal 

 native ? 



B. RELATIONS TO ORGANIC ENVIRONMENT. 



I. FOOD. 



Animals are monophagous or polyphagous, depending upon 

 whether they live upon a single kind of food or on several kinds ; 

 they are carnivorous, herbivorous, or omnivorous depending upon 

 whether they eat flesh, plants, or both. 



1. Correlation of Food and Structures. Determine by means of 

 the organs of prehension, the teeth, or the character of trie mouth 

 parts of the speciment assigned you what is the nature of its food. 

 Draw these characteristic structures. 



2. Correlation of Food and Habits. Point out, if possible, the 

 correlation between the food and the habits of the animal you are 

 studying. 



3. Storage of Food. Is this animal able to store up food in 

 any form? If so describe the process. 



II. MEANS OF DEFENSE AND OFFENSE. 



1. Active. Is the animal you are studying able to defend itself 

 actively or not? If so, draw and describe some of the organs used 

 for this purpose. 



2. Passive. If it defends itself passively describe the methods 

 and structures by which this is done.
