In association with the St Helens Island group (Seldenby) there is also an outcrop of Middle Oomian rocks. Mr. Liddell showed me a fine specimen with several quite characteristic Spirifer designata. In the case there are three other species with quite a different spiral (named like S.— [illegible] from the [illegible] Rock Island). It has fine striae in the dorsal fold. The specimens are for not separately by various forms. This material is in quite a different matrix and some of the fossils are as casts. It is in this matrix that the shells are which I found of Prof. Whiteways. Is it that they [illegible] occur in the past? In agglomerate? The once probably edge in that it is another involved shell.
