1862.] M.0.A.L. MORCH’S REVIEW OF THE VERMETIDBE. 83 
droides norvegica, Giinth.,—the variety described by Montagu as 
Serpula reversa, Mont.=S. contorta, Brown, Ill. t. 2. f. 4.= Hete- 
rodisca reversa, Flem. It is a true Serpulidous shell. 
3a. SterHoroma, n.sp. (See P. Z.S8. 1861, p. 148.) 
In the collection of Charles VIII. is preserved a lid distinctly 
spiral, of a brown colour, convex inside, and provided outside with 
long bristles, very like those of Stephopoma senticosum, Morch (Proc. 
Zool. Soc. 1861, pl. 25. f. 2), but having all the lateral spines simple, 
without any accessorial spines. It is mounted on mica, and labelled 
by the late Rev. Mr. Lyngby as the lid of a Serpula found on the 
ege-case of Raia batis (in Danish “'Tzrbe”’). That it really was 
found in the Kattegat, near Gilleleie, which was his parish, is probable 
from the circumstance that he has added the Danish specific name 
to a fish of which several congeneric species are described in his MS. 
*Rariora Codana” with Danish specific names. Unfortunately I can- 
not find his diary, in which it is more particularly described according 
to the ticket. The study of the Worm-tubes is so neglected that I 
do not regard it impossible that a Vermetid may be found in the 
Northern Seas. Perhaps it may prove to be the Spirorbis striatulus, 
Brown (Ill. pl. 1. f. 59), which is from Dunbar, in Gen. Bingham’s 
collection. 
3 6, SrEPHOPOMA ARCHIMEDIS, Konig. 1842-44, 
T. subcompressa, spirata; anfractibus quinque, ultimo remoto ; 
superficie plicato-rugosa ; orificio ovali. 
Serpula archimedis, Konig, Carb. p. 57, t. 9. f. 6. 
Serp. spinosa, Kon. Carb. p. 58, t. 9. f. 8 (T. juvenilis). 
T. depressa, planorbiformi, anfractibus quatuor, contiguis, sensim 
incrassatis, spinis in quincunces dispositis, obductis (De Konig). 
Zab. Fossil in the Mountain Limestone, at Vise (Kinig). 
The supposed young shell is from the clay of Tournay. The 
form of the aperture and the flexure of the striee of growth are quite 
that of Stephopoma. The sculpture of the supposed young shell can 
only be compared with the embryonic shell of Stephopoma senti- 
cosum, Morch (Proc. 1861, pl. 25. f. 14), which circumstance has 
guided me in giving it the present place. 
It is probable, from the appearance of a group of Vermeti ona 
Chama (in the Museum Regium), that Siphonium textum, M., S. 
scaphitella, M., and S. pictum, M., are different ages of S. subcre- 
natum, Lam., corresponding to the different forms of Siph. nebu- 
losum, Dillw.
