Lambe described
Myxilla lacunosa from a specimen from Vancouver Island. Lambe’s sponge was subsequently placed in the subgenus
Burtonanchora based on Lambe reporting smooth styles. A number of investigators, including the authors of this paper, report some styles with spines in Lambe’s sponge. We redescribe
Myxilla lacunosa based on re-examination of Lambe’s holotype, and propose to place it in subgenus
Myxilla based on the presence of spined styles rather than subgenus
Burtonanchora which is defined as genus
Myxilla with smooth styles.
