CORALLINA. 
si. Coraliina officinalis, the coralline of the (hops; 
this is trichotomous, or dividing in threes, with the joints 
of the fiem a little compreifed, and not unlike a wedge ; 
thofe of the branches are cylindrical, and thofe of the 
ends often terminating in little knobs. It is found on 
the fea-coa(ts of England, and almoft on every fhore, 
growing in clultered tufts, from two to five inches high, 
about the thicknefs of a large thread. It varies in its 
colour, being red, greenifh, yellowiih, purple, and white. 
This is the fpecies frequently given in powder, as an ab- 
forbent and vermifuge. 
22. Coraliina elongata, the trailing coralline ; tricho¬ 
tomous, with the joints of the fiem wedge-fhaped ; the 
branches cylindrical, the tops a little blunt, with knobs 
on fome of them. This is found.on the coaft of Corn¬ 
wall, and is remarkably llender, being longer and fmaller 
than the officinal coralline, and of a reddilh or purpliih 
colour. 
23. Coraliina fubulata, the coralline with pointed 
branches; this is alfo trichotomous; the joints of the 
fiem wedge-fhaped, and two-edged, fending out (mail 
pointed branches from the tops of each of their tides, 
with round joints. The appearance of this fpecies is 
very flat, white, llender, apd fmall, and looks as if very 
clofely pinnated, or with fine white fibres coming out on 
each lide, like a branched feather, every one of which 
appears to be a diftindt animal. It is the moft delicate 
of all the tribe, and was lately brought from the Well 
Indies. 
24. Coraliina granifera, the graniferous coralline ; tri¬ 
chotomous, or branched in threes, with the joints of the 
fiem compreifed, and wedge-lhaped; thofe of the branches 
roundilh ; from thefe a feries of egg-fhaped ovaries with 
ftalks grow oppolite to each other, and are fometimes pro¬ 
liferous. This differs from all the other known tricho¬ 
tomous corallines, in having proliferous ovaries, or 
branches, growing out of them, bearing other ovaries. 
It is of a beautiful fea-green colour, and llender texture. 
Native of the coafi of Africa, and found in the Mediter¬ 
ranean Sea. 
25. Coraliina corniculata, the coralline with horned 
joints; this is dichotomous, and the joints of the Hems 
have two horns ; thofe of the fmaller branches are 
roundilh. This grows on fucus’s, and is found plenti¬ 
fully in Cornwall. The younger joints, as they fubdi- 
vide, become roundilh. There is a variety of this kind 
from the Well Indies with much larger joints, and all of 
them appear horned. 
26. Coraliina criftata, the crefied or cock’s-comb co¬ 
ralline ; dichotomous, and hair-like, dividing in turns, 
with rounded joints, having its branches difpofed in 
crefied hunches, with ovaries at the lafi but one and laft 
division. This elegant little coralline is from one inch 
to an inch and a half long, and moll commonly of a 
beautiful red colour, though fometimes green, and often 
white. It is eafily known, by being difpofed in creft- 
like tufts ; it difters from the following, by having 
(horter points at the ends of the branches, and growing 
much thicker together. It is found jji great quantities 
about Weymouth and Penzance in the weft of England, 
and generally adheres to the fucus. 
27. Coraliina fpermophoros, the feed-bearing coral¬ 
line ; this is alfo dichotomous, and hair-like, with round¬ 
ilh joints, bearing ovaries at the lafi and laft but one di- 
viiion, and ending at the top with long_briftles: It is 
very (lender, feldom above one inch long; generally 
found of a milk-white colour, and never in the crefied 
form of the preceding,.but more loofe and fpread. It ad¬ 
heres to fucus’s, and grows near Penzance, in Cornwall. 
28. Coraliina rubens, the red thread-like coralline; 
dichotomous, and thread-like, with the joints of the fiem 
round, of the divilions nail-lhaped, and l’ome of the lower 
joints have two little horns. This differs from the three 
preceding, in being much longer, and lefs fubdivided at 
the top. It is generally found two inches long, and of a 
191 
red colour, and is very common on the coaft of Cornwall. 
Thefe three lull-mentioned corallines are what Dr. Job 
Bafter, in the Philofophical Tranfadtions, vol. lii. p. hi 
and 11 2, erroneoully inlifts are the true confervas. 
29. Coraliina fragiliflima, the brittle coralline ; this 
is dichotomous, or dividing in twos, with fmooth, even, 
cylindrical, joints, and erect branches. Native of the 
Weft-Indian ocean, and is much larger and fritter than 
the four preceding fpecies. It is of a beautiful milk- 
white or (ilvery colour. 
30. Coraliina cufpidata, the fpear-ffiaped coralline; 
this hath its branches often dividing into four ; the joints 
cylindrical, and united by a glutinous tendinous fub- 
ltance ; the branches end in lharo or fpear-like points. 
It is very brittle and white, grows in tufts about three 
inches high, and is found on the fhores of the Weft-Ir;= 
dian illands. 
31. Coraliina tribulus, the caltrop coralline; with 
branches often divided into five ; the joints two-edged, 
and united together by a glutinous tendinous fubllance. 
It is of a whitifli colour, and much thicker and larger 
than the preceding; found likewife on the coafts of the 
Weft-Indian illands. 
32. Coraliina flabellunt, the fan coralline ; this is the 
fined fpecies, having a fingle incruftated fiem, with the 
branches glued together into a leaf, like a fan, covered 
with a calcareous cruft, and l'omewhat waved. This 
fpecies varies from the figure of a flat kidney-fhaped leaf, 
an inch high, with a broad ftalk, to a large fubdivided, 
lobated, undulated, frond-like figure, five inches high, 
and as many broad, as delineated in the engraving : at 
the bottom of the Italic is a tuft of fine hair-like tubes, 
by which the animal fixes itfelf to rocks or Hones, like 
the fuckers of an oylter. There are many varieties of 
this curious coralline brought from the Weft Indies, of 
different mixed colours, from a greenilh brown to a 
milk-white. 
33. Coraliina conglutinata, tlte conglutinated coral¬ 
line ; this hath a fingle fiem, (lightly incruftated, with 
all its branches dichotomous and glued together, but 
not covered, forming a figure like a fan-(haped leaf. We 
can plainly diftinguilh the dichotomous branches.of this 
coralline on its furface, which are eaefy of them fepa- 
rately covered with a thin calcareous lubftance full of 
pores ; thefe, by growing fo clofe to one another, be¬ 
come glued or united by their covering. Native of the 
Bahama illands; of a fea-greeh colour, and one inch and 
a half high. 
34. Coraliina phoenix, the palm coralline; this hath 
a fingle incruftated ftem ; tire upper leafy part of an ob¬ 
long figure, with fmall fafciculated branches, which 
come forth on all iides ; the leHer branches of thefe are 
fo united together, as to appear quite fiat. This is a 
very curious fpecies, found on the coaft of the Bahama 
illands. It is of a milk-white colour, and about three 
inches and a half high. 
35. Coraliina penicillus, the- pencil coralline ; this 
hath alfo a fingle incruftated ftem, with a tuft of dicho¬ 
tomous thread-like jointed branches- at the top, like a 
pencil-brulh. This varies in the thicknefs of its branches, 
as well as in its fize ; they are found from one inch to 
four inches long; in fome the ftem is very, (hort, in 
others it is four times as long as the head. They are 
generally white. The joints are eafily diftinguilhed 
where the branches divide ; the ftem is compofed of tu¬ 
bular filaments, covered with a calcareous cruft. They 
adhere to rocks and (hells by the bale of thefe filaments, 
and are often found in the Weft-Indian ocean growing to 
(hells, many of them together. 
36. Coraliina peniculum, the mop-like coralline ; this 
has a fingle membranaceous wrinkled ftem, on the top 
of which is a full tuft of jointed dichotomous branches, 
refembling a mop. This is the moft Angular of all the 
genus, and differs from the rell by the regular wrinkles 
of the Item, which is fmall at the bale, -and grows wider
