Additional interest attaches to the green gritty marls containing remains of Cestraciont fishes at Shrewley, lately described in my paper read before this Society, owing to the recent discovery of lamellibranch molluscs at that place. Mr. E. P. Richards, a young geologist, while we were working together at the quarry, drew my attention to an impression that he had just found. Though only a mould, I felt certain that it must have belonged to a shell of some kind, and that it was something quite new in the British New Red Sandstone, and therefore of some value. On a later visit I obtained several specimens belonging apparently to more than one genus. I sent my collection, amounting to fourteen specimens, to my friend Mr. R. B. Newton, of the British Museum (Natural History), and I requested Mr. Richards also to forward his to the same gentleman. In consequence of this, Mr. Newton read a short paper at the meeting of the British Association at Nottingham about them, and he recognized three apparently marine forms, belonging, as he thinks, to three distinct genera. As Mr. Newton points out, up to the present time, this is the only record of any true shells being found in the Keuper in this country, and this fact renders the discovery of greater interest and importance. A shell resembling a Modiola was said, on good authority, to have been met with in the Upper Keuper at Pendock, in Worcestershire, many years ago, but it cannot now
