Dear Erwin,

While preparing Brian Francisco's message on Lomanotus [#21680] I discovered this message and its partner [#10797] which have been languishing unnoticed and unpublished since 2003. I'm very sorry about that, but at times I become so overwhelmed with messages that some get lost in storage. The good side is that they are never actually lost, just in a state of 'suspended animation'.

This is clearly not Lomanotus vermiformis. Without looking at its anatomy I can't be sure, but I suspect it is what I have been calling Lomanotus sp. 1. It doesn't have the white reticulate pattern, but I suspect that is a variable feature. The other possibility is that there could be more than one lobed species. Interestingly it has a pinkish patch on the head which could be a link to the red band found in small specimens. I am pretty sure the hydroid is an aglaophenid.

Best wishes
Bill Rudman
