Key to California Porifera (Page 041)

( From page 040 B) Sigmas absent. Unguiferous Anisochelae > 30 μm.
[A]
Large Styles 3660 - 4041 - 4545 μm.
Anisochelae of 2 types, the thinner have vestigial alae and look like sigmas, 32 -34-46- 53 μm. The thicker Anisochelae with alae distinct but seemingly fused to near their tips.
