GASTEROPODA. 295 
long, delicate, bipinnate frond; the pinne are four opposite and one 
terminal, each of which shoots out opposing filaments, finely fringed 
on each side. 
Length two inches; breadth an inch and a quarter. 
Found on rocks at the water’s edge, near the observing station, 
Orange Harbour. 
This species might at first be confounded with the preceding, as 
its colour and general appearance are the same; but its finely-granu- 
lated surface and the structure of the plumules show it to be diffe- 
rent. 
Figures 388, 388 a, lateral and ventral views of the animal; 388 d, 
tentacle, enlarged ; 388 c, plumule, enlarged.
