Skeleton:
Ectosome: Loose palisade of Tornotes at surface. Surface barely penetrated by Acanthostyles.
Choanosome: Somewhat confused Isodictyal reticulation of Acanthostyles, 2 - 5 spicules thick. Nodes thick.
Distribution: Southern California.
Depth: Deep water.
May = ? Myxilla fimbriata of Green & Bakus, 1994, whose spicule measurements do not match those reported by Bowerbank, 1864. In addition, Bowerbank describes it as having 2 size classes of Anchorate Isochelae. Bakus and Green report Arcuate to Anchorate Isochelae of one size class but their diagrams look like an Arcuate Isochelae. With no SEM work it is impossible to resolve the problem.
