THE DIADEM TIMPLET. 
either tentacle or lip, and bounded by a very fine 
white line on each side ; thus is produced a pat- 
tern of fine radiating lines of white on red. Some- 
times the lines are irregularly blotched and dilated, 
with ragged edges. 
Tentacles. Pellucid, nearly colourless, crossed by 
three dim sub-opaque white bars, of which the middle 
one is most distinct ; near the base ai-e two chocolate 
bars, generally divided by a central longitudinal line 
of pellucid white, giving the appearance of four dark 
spots set in square. Sometimes one bar is nearly or 
quite obliterated. 
Month. Lip whitish. Throat rich orange-scarlet ; 
the furrows darker than the ridges. 
SiZK. 
Diameter of column in button, one and a quarter inch ; height tsvo inches 
expanse of flower one inch. 
Locality. 
The south coast of Devon ; moderately deep water. 
Varieties. 
o. Patricia. The rich orange-scarlet condition ju.st described. 
fi. Plcheia. The column of a dirty light brown ; the markings of the 
marginal coronet distinct, but duller. The usually red ground of the disk 
replaced by deep brown, and the white lines by i^ellucid drab ; the whole 
intemipted by four or five bi’oad irregular radial bands of pure white. 
The bars of the tentacles obsolete. 
This fine species first occurred to myself when dredging 
oft’ Berry Head, in about twenty fathoms, in August, 
1858. Three or four specimens came up in about the same 
number of liauls. In every case the animal was adherent 
to the shell of the living Turritella terehra, a mollusk 
which is so abundant there that the dredge comes up half- 
filled with it. The base of the Bunodes clasps the long 
turreted shell, nearly enveloping it when adult, only the 
apex and the mouth of the shell being exposed. 
.Other specimens have occurred since in similar circum- 
stances; and Mr. Densham, a collector of Torquay, informs 
me that in October he obtained a group of eight or ten 
adhering to a mass of oysters.
