This division comprises four great and distinct groupes ; the Anne- 
lides, Crustacea, Arachnides and Insecta. The two latter are not in

drawings are, however, prepared ; numerous collections made ; and the 
assistance of Dr. T. W. Harris, one of our ablest entomologists, has 
been obtained for this department.
