3. PROTULA GRÆCA BRULL. 
Serpula grceca Brullé Chenu Hl. Conch. t 1. f. 5. a. b. 
(Formindsket Copi) Chenu Cours, element. 1847. p. LXXXI. 
f. 541-42 Serpula. 
Jeg har intetsteds fundet denne Art beskrevet. Teg- 
ningen er formodentlig udfort af Brullé paa den franske Ex- 
pedition til Morea i 18*27. Dannelsen af Thorax er meget 
forskjellig fra den næstforegaaende Arts. Tegningen af Dyret 
maa være udført efter en anden Maalestok end Tegningen af 
Skallen, der meget ligner Skallen af S. fascicularis Lam., 
Delessert. 
4. PROTULA MEDIA STIMPS. 
Tubes large cylindrical, rather tlnck and strong, marked with 
i ud (stinet lines of growth, irregidarbj and variably contorted, and 
adhering throughout their length. often 6 inches or more in length, 
with a diam. at the aperture of i of an ineli. 
Auimal pale yellowish ; disk (thorax) broad , membranous, 
very thin and delicate , with a scalloped margin , and extending 
ruuch beyond the extremities of bristles of the 7 segments it occu- 
pies. On the succeeding 40 to 50 segments there are no long- 
bristles , while those of the last 20 segments are very long and 
haire like. Branchial plumes (Fangetraadene) moderately large , of 
a very pale yellowish tint. The tentacula of each are about 36 in 
number, arranged in a spiral of oue turn and a quarter, with a 
thin raised membrane encircling their bases within (Stimpson). 
Protula media Stimps. Marine Invertebr. of Grand Manan p. 30- 
Hab. It is dredged on muddy and gravelly bottoms in the 
coralline zone , attached almost invariably to dead valves of Pecten 
Magellanieus (Stimpson). 
Denne Art maa efter Beskrivelsen være meget lig P. 
Rudolphi Risso. Navnet skal bringe i Erindring, at Arten 
især er almindelig paa et Sted under 45 u N.B., altsaa midt 
imellem Polen og Æquator.
