ACTINIA VIRGATA, Sp. 0. 
Base of a deep flesh-cclour, adherent to stones, not much exceed- 
ing the column when the tentacles are expanded ; when these are 
withdrawn and the column is depressed, it frequently spreads out into 
an enlarged irregular oval. Column delicately smooth, imperforate, 
non-adhesive; substance fleshy, marked by numerous (45 to 50) pairs 
of straight, purplish-blue lines, which extend from the margin of the 
disk to the angle of the column and base, where there is a circum- 
ferent line of the same colour. Each of these lines is about half as 
wide as the space between any two ; sometimes a line is broken up 
into dots. When the animal is in a contracted state, the lines are 
brought so close together, and their colour so deepened, that it 
appears nearly black. The disk has the margin closely set with azure 
tubercles, about thirty in number ; it is smooth, of a pinkish flesh- 
colour, often puffed out into a cone, at the top of which is the mouth. 
Tentacles about eighty in number, crowded in three or four rows, 
placed near the margin of the disk, moderately long, with little differ- 
ence between dimensions of those in the several series, conical, of a 
pale-brown colour, with a slight purple tinge. When contracted, of a 
dark sepia-brown. Mouth with an azure-blue spot at the oppo- 
site angles. Acontia, none observed. 
Size from half to three-quarters of an inch in height, and from 
one-third to one-half an inch in height. 
Found on the underside of stones in pools near low water-mark. 
This pretty species is not very common : it is of very quiet habits, 
and dislikes the light. When in the aquarium it hardly ever expands 
its tentacles in the day-time, and at night, if brought within the in- 
fluence of light, the animal immediately takes alarm. A specimen 
is now living in one of my tanks. A few days ago, on looking at it 
after an interval of four or five hours, I found, to my surprise, that it 
had in the meantime surrounded itself with a progeny of fourteen 
young ones, the average size of which was one-tenth of an inch in 
height and diameter, though some were smaller and some nearly 
twice as large. They were of a dull flesh-colour ; but on the larger 
ones the purplish-blue marks began, in the course of a few hours, to 
show themselves as rows of dots, with irregularly arranged dots filling 
up the spaces between the rows of each pair. Some of them dis- 
played their timy tentacles in a ludicrously old-fashioned manner. 
As to the mother, she had contracted her tentacles until they were 
little more than papillz ; the disk was puffed out much beyond their 
tips ; and the mouth was gaping widely, displaying a red throat ; the 
base was quite free, and was altogether concealed by the contraction 
of the body. 
Bunopes LisTerI, sp. n. 
Base adherent to rocks ; its diameter about equal to the height 
of the column. Column, when expanded, usually from half to three- 
quarters of an inch in height ; but one specimen extended itself to 
the length of an inch and a third, with a diameter of four-tenths of 
an inch. Surface red, beset with longitudinal rows, about twenty-
