This is the most common rhynchonellide in the entire Budleigh Salterton fauna, with more than a hundred specimens in the British Museum (Natural History) and many more in other museums. It is undoubtedly of late Devonian age, since it often occurs on the same pebbles as Cyrtospirifer verneuili. Davidson referred the form to Rhynchonella inaurita Sand- berger, apparently with confidence in 1870 but with a query in 1881. I consider the query more than justified, partly because Sandberger & Sandberger's species (1855) is recorded from an enormous range of horizons and localities from within the German Devonian, and partly because the only specimen which they figured (1855: pi. 33, fig. 5) has dental plates, which the Budleigh Salterton species lacks, and also has a much more exaggerated fold and sinus. The form is tentatively identified as an uncinulid here, but is not Uncinulus itself since the ribbing style at the commissure is different.
