is that they are frequently coiled in an elliptic instead of a circular spire, but 
this does not seem a very constant character, as they are sometimes almost or 
quite round. The best of the specimens in the Torquay Museum is the only one 
which shows the fine transverse markings, and these agree exactly with those 
of Sandberger's figure. Phillips has supplied much coarser markings in his figure, 
which do not exist in his specimen, and which were probably due to his having 
confounded it with Goldfuss's shell, which is clearly distinct according to the 
description given of it by d'Archiac and de Verneuil. 
Salter has evidently observed this distinction, as he labelled one of the 
specimens in Mr. Vicary's Collection, " Vermetus, sp. (Euomphalus radiatus, PhilL, 
not Goldfuss)." 
The species is very clearly defined by the squared appearance given to it by 
its two spiral keels, and by its very fine transverse striation. The former is not, 
however, perfectly symmetrical, as one of the keels appears to be slightly further 
from the suture than the other, so that the back of the whorls is somewhat 
oblique. On the inner whorls these keels are visible as a thread just inside the 
suture. The squared appearance is entirely dae to these keels, for the whorls 
themselves are elliptic or subcircular in section both inside and out. 
Affinities. — Eu. Schnurii, d'Arch. and de Vern.,^ has much more rapidly 
increasing whorls, with a triangular rather than a circular section, and it has 
angulated elbows rather than raised keels. 
In Eu. radiatus, Goldfuss, or Schizostoma radiata, d'Arch. and de Vern.,^ the 
shell is less symmetrical, the transverse strige more arched and coarser above, 
the upper keel very much more elongated and the whorls deeper in section. 
3. Genus. — Phaneeotinus, Sowerhy, 1842. 
This genus only differs from Euomphalus in having its whorls free ; and as 
in some species the apical whorls are united, it may be doubted whether the dis- 
tinction is of permanent value. Shells of this genus were included by de Koninck 
under Euomphahis. EccuUomphalus, Portlock, 1843, and Serpularia, F. A. Romer, 
1843, are synonyms.
