SAGARTIAD^. 
Epidermis. Pale buff, studded with dirty foreign matters. 
Did:. Dull buff, marked with a white star, which is formed by a forked 
line proceeding from the front of each primary tentacle towards the 
mouth. Two broad white gonidial radii. 
Tmtacles. Dark brown, pellucid, crossed by three narrow remote rings 
of white. Where the foot of the tentacle unites with the disk, its radius 
has a white patch, succeeded by two parallel, longitudinal, black dashes. 
Mouth. Kich buff. 
Size. 
Diameter of column one-eighth of an inch ; height one-sixth ; expanse 
of flower one-sixth. 
Locality. 
Overhanging rocks and sides of caverns near low-water mark, around 
Torquay. 
The large dark overhung pool at Petit Tor, which I have 
more than once described, is a fertile nursery of marine life. 
Though situated not much lower than half-tide level, yet, 
from the volume of water which it contains, the constancy 
of its fulness, the aspect, excluding the sun’s rays, and the 
inclination of the rocks preventing evaporation, the rough 
worm-eaten surface, both below and above the brim, is 
always wet, always dark, and always crowded with Algte, 
Sponges, Zoophytes, Worms, and Mollusks. This pro- 
fusion of riches is not always, however, easily available ; 
for though it stands in tantalising proximity to the eye of 
the naturalist, it is quite beyond the reach of his hands, 
unless he choose to Yvade into the pool and work in the 
water breast-high. 
On the 29th of June of the present year I essayed in 
this manner to rifle the promising treasury ; and the result 
by no means disappointed my expectations, though, from 
several circumstances, it was difficult to work with hammer 
and chisel. Among other things I obtained there this 
new form.
