TUBULARIADAi:. 
Gen. LXXII. TUBULARIA. — Stem cylindrical, jointed, 
branched ; polypi with a prominent mouth ; tentacula 
with suckers, the ovaries seated at their base. 
200. T. indivisa. — Straight, nearly simple ; head with two 
rows of tentacula. 
Tubular coralline, Ellis^ Cor. 31, t. xvi. f. C— T. ind. Linn. Syst. i. 1301. 
— T. calamaris, Pall. El. 81. — Common on shells from deep Avater.

201 . T. muscoides. — Stems nearly simple, and closely wrinkled ; 
head with two rows of tentacula. 
Tubular coralline, wrinkled like a windpipe, Ellis, Cor. t. xvi. f. 6 — Po- 
lypus ruberrimus. Bast Op. i. 28. t. iii. f. 2. — T. mus. Linn. Syst. i. 
1302. Pall. EL 82. — On shells beyond low water-mark. 
Stems numerous, two or three inches in height, regularly jointed or 
wrinkled, more slender than the last ; animal like the last ; outer tentacula 
about 18, inner ones about 12 in number. 
202. T. 7'amosa. — Stem dichotomously divided, branches al- 
ternate, tentacula in a single row. 
llamified tubular coralline, Ellis, Cor. 31. t. xvii. A. — T. ram. Linn. 
Syst. 1302. — T. trichodes, Pall. El. 84 — On stones Avithin low Avater- 
mark. 
Height tAvo or three inches, slender, brownish, branches ascending, annu- 
lated at their origin ; animal colourless, ovate, tentacula about 10, in an ir- 
regular circle. 
Gen. LXXIII. PLUMATELLA.— Stem cylindrical, branch- 
ed, simple ; polypi with a depressed mouth and ciliated 
tentacula. 
203. P. repens. — Stem adhering, tentacula disposed in a 
crescent. 
Tubularia repens. Mull. Hist. Ver. i. part ii. 16. — On the under side of 
stones, Lochmill-loch, Fife. 
Stem extending several inches, irregularly branched, slightly enlarging 
toAvards the aperture, dilatable ; tentacular margin divided into two lobes, 
tentacula ciliated in opposite directions. Besides a gullet, stomach, and gut, 
there is a distinct rectum, terminating in a tubular orifice seated externally 
to the tentacular margin, out of which I have witnessed the remains of the 
food swallovA^ed but a short time before, forcibly ejected.
