摘要：

A brachythoracid anterior dorsolateral plate from the Devonian of Dickson Land is described as Arctonema crassum n.g., n.sp. In discussing the systematic position of this new genus, which may belong to the Holonematidae, remarks are given on the system of lateral lines on the anterior part of the trunk in coccosteids and holonematids. It is shown that even the posterior ventrolateral plate in some coccosteomorphs may exhibit lateral line grooves. Copyright © 1969, Wiley Blackwell. All rights reserved
