R. Etheridge, jun.—Carboniferous Tubicolar Annelida. 365 
worm-tube with which I am acquainted, I propose for it the trivial 
name of vermetiforme, in allusion to its general resemblance to some 
forms of Vermetus. S. vermetiforme approaches nearest to S. Archi- 
medis, De Koninck, but having compared it with examples of this 
species in the National Collection, I can pronounce on their distinct- 
ness. It wants the strong transverse ridges and elongated drawn- 
out form of the latter. 
I am indebted for the loan of the specimen to the Rev. G. 
Oldridge de la Hey, of Marple, Cheshire, who found the specimen, 
and forwarded it through Dr. H. Woodward. 
Loc. & Horizon.—Castleton, Derbyshire, in Carboniferous Limestone. 
16.—Serpula? (or Serpulites ?) sp. ind. 
Obs.—I gave a figure, published in a paper in a late number 
of the Proceedings of the Glasgow Nat. History Society,’ of what 
appears to be a Serpula boring into a Crinoid stem. ‘The tube in 
question is small, dark, and shining, with the peculiar bluish-bloom 
so often seen on the tubes of the Carboniferous Serpulites. Little 
more can be said about it, but we may hope for further specimens 
when the true character may be revealed. 
Loc. & Horizon.— Woodend Quarry, near Fordel, Fife (J/r. J. Bennie). 
IV.—Genus Vermilia, Lamarck, 1818. 
(Hist. des Anim. sans Vertebres, v. p. 368.) 
Obs.—The genus was proposed by Lamarck for tubes adhering by 
their whole length to submarine bodies, cylindrical in form, attenuated 
towards their posterior termination, more or less twisted, and with a 
round aperture frequently having from one to three projecting 
denticles. 
Vermilia is met with to a certain extent in Secondary rocks, but 
increases in species in the Tertiary formation. So far as I am aware, 
only one Carboniferous species has been described, V. minuta, Brown, 
and another in the Permian of this country by Prof. King, V. obscura. 
It is, however, not improbable that Serpula minuta of Eichwald*? may 
be referable to this genus, in which case the name will require 
alteration so as not to clash with V. minuta, Brown. 
V. minuta as figured by Brown is’ a small, simple, curved, horn- 
shaped body, and appears to be rare. It is quite different to the 
more or less convoluted Carboniferous tube attached to Crinoid stems 
one is accustomed to meet with under this name in Collections, which 
much more closely resembles V. obscura, King, as very justly stated 
by Messrs. Armstrong and Young.’ 
I have never had the satisfaction to examine a specimen in anything 
like a good state of preservation, and will therefore not perpetuate 
the mistake, I have in common with others frequently before made, 
but will simply refer to this species as Vermilia (sp. ind.) ; indeed, I 
have not seen any clear proof that it is a Vermilia at all.
