a curious circumstance, that not long since, my kind friend, 
the Rev. W. Bingley, presented me with a remarkably 
distorted recent specimen (perhaps I should call it a mon- 
strosity) of Buccinum undatum with a very elongated spire, 
twice as Ion'? as the lower whorl, and with a single spiral 
j-ounded ridge embossed on the upper part of it. 
BUCCINUM rugosum. 
TAB. CX* — Fig. 3. 
Spec. Char. Shell ovate-elongated, obtuse, trans- 
versely striated ; spire with twelve or fourteen 
angles; whorls five, prominent ; aperture ob~ 
ovate, latter whorl rugged. 
Aperture about one-third the length of the shell, rather 
broadest at the lower part, the sinus in the beak scarcely 
recurved; the angles on the spire are large undulations, 
something like those on B. undatum, but more elevated 
and regular. The apex of the spire is truncated and 
thick, showing that the egg must have been rather large. 
Received from Holywell, by favour of Mrs. Cobbokl : 
specimens are found of various sizes, sometimes quite white, 
and often stained with ochre, especially in the hollow parts, 
prettily relieving the projections. Its general form bears a 
great resemblance to Murex rugosus, tab. 34, but it wants 
the canal in the beak.
