fmooth , oblong Salacia . 
This is about two inches and a, half long, and an inch and a half in diameter : the 
furface is perfectly fmooth; the colour a very pale grey, and the fubftance fofi and 
tender: it is larger at one extremity than at the other, but obtufe and rounded at both • 
it’s whole furface is fmooth and gloffy, and, when the fun ihines on it, is very bright • 
toward the fmaller extremity there are feveral clutters of tentacula. 
It is common on the coaft of Portugal. 
The other fpecies of the Salacia are, i. The fmall, furrowed Salacia. 2. The fmall 
pundated Salacia, with ffiort tentacula. 3. The larger, thick Salacia, with numerous

actinia. 
^ H ^ H E body of the Adtinia is of a naturally cylindnc, but variable, figure: 
the tentacula are very numerous, and are arranged in feveral feries about the 
mouth, which is placed at one of the extremities of the body. 
AEUnia tentaculis verficoloribus, cauda tricufpidi . 
The AEUnia^ with changeable-coloured rays, and a tricufpidate tail 
This is an extreamly elegant fpecies : it lodges itfelf in little cavities of rocks, and 
of the larger lea-plants of the ftony kind, and only appears on their furface, when all 
is quiet about it: it’s body is naturally of an oblong figure, and equally thick in all 
parts, and feems, in a moderate date of extenfion, to be about half an inch long; but 
the creature, at pleafure, contra&s it almoft to nothing, and extends it to a great 
length : it’s tail is divided into three parts, or, as it were, terminated by three points; 
thefe it fixes into fome cracks of the body it inhabits, and by that means fixes itfelf 
very firmly in it’s place. When all is quiet about it, it advances it’s other extremity, 
at which is the mouth, to the furface of the done, and difplays all round it a great 
number of tentacula, formed like fo many rays, and dlfpofed in two or three feries 
fucceffively fhorter than each other ; thefe are in a continual, vibratory motion, and by 
that means draw fmall animals that inhabit the water into it’s mouth for food: the 
whole animal is of a pale flefh colour, except thefe tentacula, which are of a conic 
figure, and have a beautiful variety of colours, red, yellow, and blue, and many 
others: when they are fully expanded, they give much of the appearance of fome of 
the flower of the compofit; flowered plants. 
It is not uncommon on the coafls of the American iflands, and in the fall-water 
ponds on feveral of them. 
* i'\ V J- \ . 
AEUnia corpore ventricofo^cauda fimplici , tentaculis planis 
The AEUnia , with a ventricofe body, a fi??2ple tail , and plane tentacula . 
This is a larger, and, if poffible, a more elegant fpecies than the former : it’s body, 
in what feems it’s ftate of greateft reft, is oblong, rounded, and fomewhat bellied in 
the middle: it has fix ridges running longitudinally at equal diftanees, from end to end 
of it, and the tail is Ample ; between thefe ridges there are feveral rounded, deprefied 
ipotSj of a paler red than the reft; the ridges alfo are pale, the reft of the body of a 
ftrong flefh colour. It buries itfelf, in the manner of the former, in a cavity of fome 
rock, and at the furface difplays if s tentacula in three or four diftinCt feries round the 
mouth, which is a large opening, of an oval figure, at the extremity of the body : 
the tentacula are fucceffively fhorter from the outer circle to the inner one; they are 
all of a pyramidal figure, thin and fmooth, and tinged with a beautiful variety of 
colours. 
It is found on the coafts of America and of the Eaft Indies, in the cavities of 
rocks.
