Skeleton:
Ectosome: Dermal membrane with Isochelae, below which are Tornotes more or less tangential to the surface.
Choanosome: Dense mesenchyme with ill-defined tracts to surface. These crudely echinated by Styles. The tracts form a loose reticulation.
Distribution: Southern to Northern California.
Depth: Intertidal to deep water.
Note: This form differs from the original description of Lissodendoryx kyma by having mostly Styles. If spined they are usually not as pronounced as those described by de Laubenfels. This is the most common form in California. See Page 142A, 142B and 166A for important information.
