The sponge in the Honolulu Aquarium had 
pale flesh-colored Ascon tubes only about 
300 microns in diameter. The spicules were 
principally triacts, with rays 11 by 110 mi- 
crons. Tetraxons were probably present but 
were rare, as in other specimens of eleanor. 
The oxeas were chiefly ectosomal, 10 by 150 
microns in dimension, often hastately pointed 
at one end. 
It is of exceptional interest to observe the 
relationship of this aquarium fauna to that of 
the east shore of the Pacific. Except for the 
two new species, and the possible exception 
of the Oscarella (probably merely overlooked), 
all these species occur also on the Pacific 
coast of North America.
