New upper Homerian (uppermost Wenlock, Silurian) monograptids from Arctic Canada
Five species of new or little-known upper Homerian (uppermost Wenlock) graptolites are described from the Arctic Islands. These are Lobograptus? sherrardae (Sherwin), Lobograptus? aff. sherrardae, Lobograptus? claudiae Koren, Lobograptus? cf. cornuatus Lenz, and "Pristiograptus" schedidone...
