56 Couthouy's New Species of Mollusca 
TUBULARIA coronata, Mull. 
Zool. Dan. vol. iv. pag. 95. tab. 141. 
This species is very distinct from the preceding, by 
being in every respect much smaller, and, instead of 
growing in tubes detached or connected only at the 
base, it is found in clusters composed of innumerable 
ramifications. The stems or peduncles are of a bright 
rose color, the interior tentacule upright, penicillate and 
of rather a deeper color.

TUBULARIA STELLIFERA. 
T. tubulis brevibus, simplicibus, aggregatis, carnosis, stellis parvu- 
lis purpureis coronatis, 
T. with short, simple, fleshy, rose colored peduncles, 
associated in masses or clusters, but not ramose; each 
stem rising from a separate base; the polyps small, stel- 
liform ; inferior tentacule of a beautiful purple and highly 
contractile; superior or internal ones of a bright crimson. 
Height of peduncle about ten fortieths, diameter one for- 
tieth; diameter of polyps four fortieths of an inch. 
Habitat Boston Harbor. 
This delicate species was found by me the summer 
before last, growing about the bottom of the piles at 
Craigie's bridge, in the neighborhood of which, it should 
have been observed, the two preceding species were also 
found. At first sight it very much resembled some of 
the cryptogamous plants ; and it was not till after a close 
examination that I was convinced of its being a polyps- 
I have no doubt, after comparing it with the descriptions 
of known species, that it is as yet undescribed. Re-
