Spongia lapidescens subsp. mauritiana var. decidua Hyatt, 1877

Spongia lapidescens subsp. mauritiana var. decidua Hyatt, 1877: 528 .

Hyattella decidua; Von Lendenfeld 1889: 110, pl. 20 fig. 3.

Hyatt’s name is not an available name (as it has a fourth name, ICZN art. 45.5). I propose to assign this material from Mauritius to Hyattella sinuosa (Pallas, 1766) in accordance with Ridley (1884: 592).
