No.1.] BUDDING IN GOODSIRIA AND PEROPHORA. 223 
type represented by Pevophora. But more knowledge of the 
embryology of each genus is requisite before this or any other 
conclusion respecting their relationships will be fully warranted. 
5. In neither Goodstvza nor Perophora is there an epicar- 
dium comparable with the structure called by that name in 
Clavelina and many other Compound Ascidians. 
6. The budding of Goodstria greatly strengthens the con- 
clusion justified by adult structure that the Polystyelidae and 
Botryllidae are very closely related. The two families will 
probably have to be ultimately united into one, but it is not 
best to do this until we know the embryology of both groups 
much more fully than we yet do.
