Cape Smyth, Canada Lee Billings Street St Johns Shore seen Streptolasma canadensis Gyospira concinnatissima; large burnt or large so B. described by James. Lord specimen m a slab. A. caparis one m a egg of a Streptolasma. The material appears fine good and abundant. Aspidella terranovica. On fresh fracture there are mere films of concentric lines crossed by the finest kind of radial lines that start from a central point. Originally they were pretty circular but are now more or less drawn out. To me they look like concentric growths and are due to diagenetic causes. As weathered specimens some of the con- centric lines become more conspicuous than others. The radial lines remain about the same due to them being in the stone as original physical characters.
