392 M1LLEPORA, 
cylindrical pores, almoft like ftars ; as fhown on the an¬ 
nexed Plate, at fig. i. This coral grows in immenfe mafies 
in the Eaft-Indian Ocean ; it is nowand then brought us 
from Prince’s Iftand, in the Straits of Sunda. The lami¬ 
nae, or plates, are generally half an inch thick, and full 
of minute pores between the cellular ftarry cells, which 
both pafs from each furface to the central longitudinal 
veifels in nearly a perpendicular direction, and with which 
they are united. The furface, when magnified, is full 
of little (harp points between the fmall pores and round 
the larger; and, when we examine the larger ftellated 
pores, we find them furrowed on the infide to the bottom, 
which makes a proper tranfition from this genus to the 
Madrepores. 
4. Millepora afpera, or prickly millepore: fomewhat 
compreffed and muricate, with eminent pores which are 
cleft here and there. Inhabits the Mediterranean and 
Norway feas. Erefif, pointing two ways, roundilh, with 
crowded pores at the branches cleft on the lou'er fide. 
5. Millepora folida, or folid millepore : turbinate, with 
very crowded angular pores; the tubes of pores with 
tranfverfe divifions within. Found caft on the Ihores of 
Gothland. 
6. Millepora miniacea, or fmalleft millepore: very mi¬ 
nute, branching into fmall lobes, and covered with very 
fmall pores. This beautiful little coral is the fmalleft of 
the tribe, being feldom above a quarter of an inch high. 
The whole furface,when magnified, is full of minute white 
blind pores; but on the tops of the lobes we may obferve 
fe.veral fmall holes, fcattered here and there, that are fur- 
rounded by a margin ; thefe are properly the little cells. 
It has a broad bale by which it adheres to Ihells, corals, and 
rocks ; and is found not only in the Weft Indies, but in 
the Mediterranean Sea and the Eaft Indies. 
7. Millepora cervicornis, or ftag’s-horn millepore: a 
little comprefted, dichotomous, with cells on both lides, 
and tubular fomewhat-prominent openings. Inhabits the 
Mediterranean and Cornifh coafts; from five to fix inches 
high; colour reddilh or yeliowifh-brown, within whitifh; 
branched like the horns of a flag, and appearing as if co¬ 
vered with varnifii. Very brittle, and much narrower 
than M. fafcialis, but not fo flat: a few of the pores are 
divided at the bale, as in M. afpera. 
8. Millepora Skenei, or Skene’s millepore: compreffed 
and flightly branched, with cells on both lides dilpofed 
in, alternate rows ; cells turbinate, with a gaping mouth, 
and covered with a helmet, the under-lip furnilhed with 
a fmall tooth. Found near Aberdeen, adhering to rocks, 
by Dr. Skene, who communicated it to Mr. Ellis. It is 
of a bright Ihining white colour, and appearing as if co¬ 
vered with a filver varnilh. 
9. Millepora pumila, or dwarf millepore: deprefled, 
with fcattered irregular ret life branches every-where po¬ 
rous and roughilh. Inhabits the Mediterranean, on Ihells 
and rocks ; three inches high, folid, very much branched, 
pale grey, within white. 
10. Millepora compreffa, or compreffed millepore: fur¬ 
nilhed with a Item (lightly branched and a little com¬ 
preffed; branches diftant; pores every-where a little pro¬ 
minent and rough. Inhabits the Mediterranean. 
xi. Millepora lichenoides, or liver-wort millepore: 
caulefcent, decumbent, with waved nearly-oppofite den¬ 
ticulate branches; pores a little prominent on the upper 
fide and ftriate beneath. Inhabits the Mediterranean and 
European coalls, on (tones and other marine lubftances ; 
milk-white, very brittle, and about tw'o inches long. 
11. Millepora violacea, or violet-coloured millepore: 
flat, branching, with ereft flexuous round branches a 
little comprefied, with ^.-porous future encompalfing the 
margin. This coral is of a fine violet-blue. It rifes from 
a lpread bale about three inches high: befides the line of 
large pores that lurrounds the margin, there are two rows 
of Imall pores, one on each fide of it. The furface, when 
magnified, is rough like (hagreen; and here and there 
upon it are clulters of little warts, like ftuds or builulx, 
which may probably be its ovaries. When the branches 
are broken acrofs, there appears in the middle a row of 
three or four large pores, furrounded by fmall ones. In¬ 
habits the illands in the South Sea. 
13. Millepora tubulifera, or tube-bearing millepore: 
folid, branched, with tubular fcattered pores ; branches, 
confluent, with tapering rough extremities. Inhabits the 
Sicilian feas ; about four inches high, white, folid; the 
trunk and larger branches fmooth. 
14. Millepora fafcialis : membranaceous, fiat, narrow, 
branched,.flexuous, with pores on both lides. This fpe- 
cies grows in very irregular mafies, but always preferves 
the lame habit of growing; that is, the branches are flat, 
narrow; and regularly lubdivided: they coalefce, twill, 
and branch out again, leaving certain hollow fpaces be¬ 
tween them; their cells are much imalier, though of the 
fame lhape, with the cells in the M. foliacea. This coral 
was brought from the Mediterranean Sea, and grows in 
large mafies of fix inches diameter. 
There is a kind, fomething like this, found on the 
coaft of Cornwall; but the branches are not fo flat, and. 
the cells have more elevated openings, liker to the M. cer¬ 
vicornis. BorlaJ'e Hift. Cornwall, tab. 24. fig. 7. 
15. Millepora foliacea, or foliaceous millepore: folia-, 
ceous, flexuous, uniting here and there at the extremities, 
and covered with hardly-vifible pores on both furfaces. 
Found by Ellis, growing to an oyfter-fhell, in the Ille of 
Wight. It is indeed very common on various parts of 
the lea-coaft of the Britilh illands, where it occurs in 
mafies from three inches to a foot long. It is frequently 
obferved incrufting Hones and fnells; and, like Ibme of the 
Fiuftras, or lea-mats, it firft forms a Angle layer of celis, 
and riles up with a double layer afterwards into twilled 
leaf-like ftony mafies, with cells on both Tides, dilpofed 
in a quincunx order. 
16. Millepora Zeylanica, or Ceylon millepore: white, 
compofed of thin concrefcent irregularly-divided mem¬ 
branes, with rows of oblong cells each fide. Inhabits 
the Indian Ocean. 
17. Millepora forniculofa, or arched millepore: crufta- 
ceous, with rows of vaulted cells, furnilhed with a fmall 
ringent lip, and clofed by a membrane. Inhabits South 
America, adhering to other corallines: relembles the 
Fluftra foliacea, and may probably be a Cellepore. 
18. Millepora cruftulenta, or lcaiy millepore: crufta- 
ceous, fomewhat branching and irregularly fhaped, with 
rows of oblong ceils doled by a membrane, and very en¬ 
tire divifions. Greyilh-white, and forming iubglobular 
maffes. Inhabits the fait dykes of Holland, and the At¬ 
lantic. 
19. Millepora erofa, or toothed millepore : cruftaceous, 
with open celis pedinate at the lateral margin ; the cells 
with ereft Tubulate teeth, about four each fide. Inhabits 
the American Ocean; affixed to rocks. 
20. Millepora reticulata, or netted millepore : mem¬ 
branaceous, with anaftomofing deprefled linear branches, 
rough on the upper furface, with prominent pores. This 
rare fpecies inhabits the Mediterranean and Weft Indies. 
It is white, brittle, horizontal, convulute, and very much 
branched; the reticulate branches growing in an undu¬ 
late manner, and coalefcing here and there: the under 
furface fmooth. 
21. Milleporacellulofa: membranaceous, reticulate,fun¬ 
nel-form, irregularly waved and plaited at the margin, 
with numerous pores on one fide only. Though this ele¬ 
gant little coral is found now and then on our. coalt, we 
cannot boaft of thole beautiful forms that we find in fpe- 
ciinens from the Mediterranean Sea. Ours is generally 
funnel-lhaped; but the foreign is more loofely folded and 
waved, and looks like a lace-ruffle. The under part is 
quite fmooth between the openings; but the upper fur- 
face is full of cells, which are difpofed in a regular quin¬ 
cunx order. It is about three inches high, lolid, brittle, 
white, or yellowilh-grey, with very vivacious polypes. It 
is reprefented on the Plate, at fig. 2.
