«DESCRIPTION OF A NEW BRITISH SHELL.—THE CLOUDED SCALLOP. — Pecten Nebulosus.— Shell almost circular, ears nearly equal in size, with seven broad, unequal, and flattish ribs; external surface of both valves covered with very fine, parallel, longitudinal striae, and also with minute, undulating, transverse striae, which are hardly discernible to the naked eye, but feel rough to the touch. Both valves are somewhat inflated towards their base, with a longitudinal series of densely-set ribs, and the margin finely crenulated, two-thirds the length of the shell. The upper, or convex valve, is of a rich, reddish brown, irregularly clouded with white; under valve, cinereous, and immaculate; inside white, of a pearlaceous lustre, exhibiting slightly iridescent reflections. Length, one inch and seven-eighths; breadth, the same. The specimen from which the following figure was drawn was found at Largs, mouth of the Clyde, in July 1834.
We are indebted for the discovery of this beautiful species to that zealous naturalist, Mr John Blythe of Glasgow. He first noticed some fragments of this shell about seven years ago, while examining the shores at Millport, and afterwards found a perfect specimen. Mr Blythe informs us that the shell is not uncommon in Lochfine, and that his friend, Mr Drew, writer, Inverary, has procured several live specimens attached to the lines employed in cod fishing. They live in very deep water. We read an account of this shell before the British Association at Edinburgh in 1834. and were then doubtful whether it was an undescribed species. We thought that it might possibly be the Pecten aspersus of Lamarck, as it is nearly allied to it in form and markings. We thought that Lamarck's might be the young shell. Since that time, however, Mr Blythe has kindly presented us with two young specimens, in both of which the ribs, or rays, are seven in number; whereas Lamarck says his shell is five-ribbed; and we hardly think so acute an observer would have overlooked the transverse undulating strite.» THOMAS BROWN, 1835
