Porolepiform scales from the Lower Devonian of the Holy Cross Mountains, Poland, described from the ‘placoderm sandstone’ of the Daleszyce area, are revised. The aim of the present article is to organize the recently collected, but not formally described, porolepiform material from the Holy Cross Mountains, as well as specimens from erratic boulders collected near Gdynia (northernmost Poland), which can be referred to Porolepis. Previously collected and new material was found to contain at least two sarcopterygian taxa: Porolepis and Heimenia. Based on morphological and histological features, the described material has been divided into two scale assemblages. The first, which is assigned to Porolepis, possesses cosmine cover on the entire exposed area; in the second, assigned to Heimenia, the cosmine cover is reduced or absent. These features prove to be stable regardless of the position of the scale on the body and thus are taxonomically informative.

修改了从达列日采地区的“ placoderm砂岩”中描述的来自波兰圣十字山脉下泥盆纪的孔隙形鳞片。本文的目的是组织最近从圣十字山脉收集的但未正式描述的porolepiform材料，以及在格丁尼亚（波兰最北端）附近采集的不稳定石块的标本，这些标本可以称为Porolepis。以前收集并发现新材料至少包含两个翼翅目分类单元：波雷俄比斯（Poleolepis）和海明尼亚（Heimenia）。根据形态和组织学特征，所描述的材料已分为两个比例组合。第一个，分配给Porolepis，在整个裸露区域都具有胭脂红覆盖层；在第二次分配给Heimenia的情况下，减少或缺少了该胭脂红的覆盖范围。这些特征被证明是稳定的，无论体重秤在人体上的位置如何，因此在分类学上都是有益的。
