Sponge: No information.
Color: Alive: Light orange.
Spicules: Megascleres: (1) Subtylostyles-some polytylote: 220 -227- 240 um. x 5 um. Microscleres: (1) Arcuate Isochelae: 18 -21- 24 um. (2) Arcuate Isochelae ?: 9 um.
Skeleton: No information.
Distribution: Anacapa Id. Southern California.
Depth: Intertidal.
This species was so incomplete that it is virtually impossible to identify it. The small chelae were thought to be aberrant or a contaminant. Likewise, the lack of ectosomal tylotes or subtylotes suggest some other genus. No illustrations available.
