170 MOLLUSCS IN UPPER KEUPER AT SHREWLEY. [May 1 894, 



13. On tlte Discovery of Molluscs in the Upper Keuper at 

 Shrewley in Warwickshire. By the Rev. P. B. Brodie, 

 M.A., F.G.S. (Read March 7th, 1894.) 



Additional interest attaches to the green gritty marls containing 

 remains of Cestraciont fishes at Shrewley, lately described in my 

 paper read before this Society, 1 owing to the recent discover 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 obtaiued 

 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. 2 



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 Worcester- 

 shire, many years ago, but it cannot now be found, and no further 

 account was given of it. The matrix at Shrewley Quarry is 

 unfortunately most unfavourable for the preservation of testacea, 

 and it was very difficult therefore to determine those now, for the 

 first time, detected in the New Red Sandstone in Britain. 



The shells are fairly abundant, and they occur as far as can be 

 ascertained at one end of the section, just above the red marl at 

 the base, though they may be present in the same position else- 

 where, and if the green marls could be got at, which cannot now 

 be done, other and better specimens might be secured. Mr. Newton 

 proposes to describe them in more detail and to give figures of the 

 best examples. 



Discussion. 



Mr. R. B. Newton referred to the indebtedness of the Society to 

 Mr. Brodie for his various communications on the Keuper of 

 Warwickshire. The specimens found by him and by Mr. Richards 

 were obscure impressions of lamellibranch shells, three of which he 

 (the speaker) had selected for detailed description. The discovery 

 of true marine fossils in the Shrewley Keuper was of the utmost 

 importance, and the Author therefore deserved the thanks of 

 geologists.
