struction is given on the approved methods of collecting 
and preserving insects in all stages of development. Col- 
lections are made in each of the various habitats, and the 
material identified in the laboratory. Opportunity is 
afforded to form individual collections of properly deter- 
mined specimens which should be of considerable value to 
teachers. ‘The identification of immature forms is in- 
cluded in the systematic work. Familiarity with the 
available entomological literature is encouraged. Two 
half days of field and laboratory work and one confer- 
ence weekly. Two hours credit. Mr. WELCH. 
6. Special and Research Work m Zoédlogy—this 
course does not involve formal instruction, but is intended. 
for those who wish to take up special work or to do re- 
search work under direction. Students qualified to work 
independently may choose problems to meet their indi- 
vidual needs. Such students register under Dr. Ellis, 
who has general supervision of zodlogical research. Stu- 
dents who are beginning research, or who work under 
direction are recommended to choose subjects in the fol- 
lowing fields: 
a. The Fishes or Sporozgoa. Dr. Evuts. 
b. The Oligochetes or Fresh-water Sponges. As- 
sistant Professor SMITH.

habits of the commoner species, and with the correlation 
between their habits and structure. ‘The work consists
