). Two slight variations in spicule size were noted in this specimen: tylote thickness reaches a maximum of 16 µm whereas the thickest tylotes described by Lundbeck (1905) are 11 µm. The acanthostyles in this specimen do not exceed 350 µm, whereas Lundbeck states that acanthostyles can reach 450 µm. Vosmaer (1882) described this species as being of a “pitchy colour” and having a cup-shape. Lundbeck (1905) describes the sponge as leaf shaped and erect with an attachment to the seafloor at the base. The overall spicule complement in the present specimen is very similar to Lundbeck’s (1905) description. The bipocilli in the present specimen are rounded, with numerous fine teeth, similar to those described in Lundbeck (1905). However, Lundbeck (1905) also describes some bipocilli that attain “monstrous forms” where the alae split from the shaft, but these

of spicules were not seen in the present specimen. Despite minor variations in spicule size, the present specimen agrees with previous descriptions, especially in growth form and colour.

The cup-shaped growth form, thick acanthostyles, bipocilli with fine teeth, and pitch-black colouration are clear identifiers of this species, thus the difficulty of the authors to identify their specimens to the species level suggest congeneric species are present in their samples.
