Spongia equina subsp. cerebriformis var. mexicana Hyatt, 1877

Spongia equina subsp. cerebriformis var. mexicana Hyatt, 1877: 521, pl. 16 fig. 28.

Spongia obscura Wiedenmayer, 1977: 56 .

Hyatt’s name is not an available name (as it has a fourth name, ICZN art. 45.5). As proposed below, I assign this material from Vera Cruz, Caribbean Mexico to Spongia (Spongia) obscura Wiedenmayer, 1977 .
