VAN NAME: COMPOUND ASCIDIANS. 419 
were correctly identified with this species. A number of Dr. Yarrow's 
original specimens are in the Yale Museum, and though they are in 
a very poor state of perservation, it is safe to say that most of them 
are not A. sfelJatiim. There is one colony which may be of this 
species, but its condition is too poor to be certain of it.
