Syringopora colonies from the Mississippian Banff, Livingstone, Mount Head, and Etherington formations of the southern Canadian Rockies were analyzed for such features as corallite diameter and spacing, wall thickness and tabular pattern. Results of this inquiry indicate that corallite diameter and spacing (frequency) are most important in distinguishing species. Eight species and 2 forms are recognized. These are Syringopora harveyi forma agglomerata n. forma, S. harveyi White, S. surcularia forma compacta n. forma, S. surcularia Girty, and S. rudyi n. sp., mainly from the Banff formation (Kinderhookian and lower Osagean); S. dingmanae, n. sp., and S. bassoi, n. sp., from the upper Livingstone and lower Mount Head formations (upper Osagean and lower Meramecian); S. virginica Butts and S. magnussoni, n. sp., from the upper Livingstone, Mount Head, and lower Etherington formations (upper Osagean to lower Chesterian); and S. drummondi, n. sp., from the upper Etherington (upper Chesterian). The type specimens of Syringoporella? monroense (Beede) are redescribed and figures.
