Catalog entries: Stylotrochus

Original description: Radialstacheln sämmtlich in einer einzigen Ebene liegend. welche sich in der Mitte zwischen den beiden Flächen der Schwammscheibe befindet und diesen beiden Flächen parallel läuft.
Remarks on original description: Campbell [1954, p.D94] considers Stylotrochus to be an objective synonym of Stylospongia Haeckel, 1862. However, this seems inappropriate as the type species of Stylospongia [Stylospongia huxleyi Haeckel, 1862] was not among those species assigned to Stylotrochus at the time of its generic definition. Species included at that time are: Spongotrochus arachnius Haeckel, 1862 and S. heteracanthus Haeckel,1862.
