182 Zoological Society :— 
four in number, of small white tubercles, which have a spot or streak 
of red at their apices. There are from ten to sixteen tubercles (taking 
different specimens) in a row; these tubercles can be employed as 
suckers, and by them I have seen the animal adhere to the bottom 
or side of a glass in which it was living ; the alternate rows some- 
times cease with the third or fourth from the disk. Disk frequently 
cup-like, without marginal spherules, very transparent, with a row 
of small white spots at the inner base of the innermost series of ten- 
tacles: sometimes there are white spots between the tentacles. Mar- 
gin of disk uneven, by reason of the highest tubercles of the column 
forming part of the outline. Mouth with a pale ring around it. 
Tentacles numerous, in about three rows near the margin of the disk, 
those of the innermost row longer, and these are as long as the dia- 
meter of the column, decreasing in size outwards, pale flesh or 
brown, but sometimes bearing white opake spots, very pellucid, coni- 
cal, simple, readily retractile, and usually brown, curled at the tips. 
This pretty species is very distinct from all the other Madeiran 
species that have occurred, but it seems to be closely allied to the 
British Bunodes Ballii. The pale-red, diaphanous tentacles become 
in some cases, when contracted, of a red-purple colour, in others of a 
brown hue. In one specimen, which was brought to me much 
wounded, the red tubercles of the column were ringed with greenish 
yellow. The animal is rather impatient of light, and is only seen 
fully expanded at night. It adheres very firmly to the object it is 
seated upon, and will submit to be torn rather than loosen its hold. 
I have named this species in honour of Dr. N. Lister, of Funchal, 
to whom I am indebted for much sympathy and assistance in my 
investigations. 
ALICIA, gen. n. 
Base adherent at pleasure; greatly exceeding column. Tentacles 
simple. Margin of disk simple, without spherules. Column beset 
with stalked appendages. 
ALICIA MIRABILIS. 
Base pale brown, adherent apparently by means of minute round 
suckers scattered over it, capable of great dilatation, and sometimes 
having a diameter of between 4 and 5 inches; very transparent, so 
that the appendages on the column could be seen through it. The 
outline undulate; the surface marked with about a hundred radi- 
ating furrows, meeting in the middle, and causing the margin to be 
erenate. Column apparently imperforate, pillar-like, when fully 
expanded measuring 23 inches in height and diameter ; surface deli- 
cately soft, pellucid, pale brown, marked with longitudinal furrows 
corresponding with those on the base; beset with stalked appendages. 
At the base these appendages are small, nearly sessile, and bear at 
their summits a single wart of hemispherical outline and of a dull- 
purple hue ; they become larger in proportion to their height above 
the base, until those next the oral disk have stalks half an inch high 
and 3, of aninch in diameter, which divide and redivide, each ulti- 
mate division always crowned with a wart. As many as sixty warts
