The main axis and the axis of the filaments are composed of tightly packed styles 1 longitudinally arranged. In the main axis, the styles most often have a blunt point, whereas those in the filaments are mostly sharp pointed, with the point directed outwardly. The diverging bouquet at the extremity of the filaments is composed of styles 1 which are less fusiform than those of the main axis and those of the axis of the filaments. A dense, irregular feltwork of styles 2 surrounds the base of the filaments near their attachment to the main axis. The small crest on the middle of the main axis and the conical spines present there are made of styles 1 with their point outwardly directed. Styles 3, short and thick, sometimes substrongyles, are the main spicule category in the attachment base. They are also present in places in the main axis, where they are irregularly arranged and generally longer than in the attachment base. The abundance of these thick styles is variable in places, or altogether absent. Given the incomplete character of all the specimens, it is not possible to ascertain if these variations in megasclere composition of the skeleton are due to the proximity to the sponge base. In places where they are well preserved, the filaments have a coating of arcuate isochelae in a Velcro-like arrangement with the alae and teeth outwardly exposed (
