In 2012 we lost Jean Jacques Peters, former engineer of Flanders Hydraulics Research (1964 till 1979) and international expert in sediment transport, river hydraulics and morphology. As a tribute to him we have created potamology, a virtual memorial archive whose aim is to preserve and disseminate his way of thinking and his morphological approach to river problems all over the world.This archive provides four modules, each with its specific information set relevant to Peters’ work. Where available and if not confidential, there will also be access to the full text. In dialogue with Peters’ family we continue to make his life’s work accessible.
The genus Trachypora Milne-Edwards & Haime 1851 was originally established for the species T. davidsoni Milne-Edwards & Haime 1851, which is unsufficiently known; therefore the use of this generic name should be avoided. Most of the Devonian species of the Old World assigned to this genus by subsequent authors belong very probably to the genus Hillaepora Mironova 1960. The American Devonian species are either members of the family Dendroporidae de Fromentel 1861, or species of the genus Thamnoptychia Hall 1877. Consequently, the use of the family name Trachyporidae Waagen & Wentzel 1886 also should be avoided.
