Hi Bill,
I'm fairly sure Alan's animal is Dendronotus perhaps (?frondosus). Now I'm sure you'll go - where are the branched processes? Look carefully at the 'cerata' - I think they are slightly branched. I'm not sure if these small ones are really D. frondosus at all, as they do seem to spawn at this size - see the eggs below in Alan's photo. It might be that they are a distinct species. I'm not sure if the hydroid is Sertularia argentea, but if it is, then that is what I've found these small grey Dendronotus on here in the UK.

I have looked out a photo of this odd Dendronotus from Ireland to accompany my message. April 1982 - Killary Harbour, Co. Galway, Ireland. - size 8mm. Photo: B. E. Picton.

Thanks Bernard,
An interesting suggestion. Perhaps Alan has a photo showing the 'cerata' more clearly.
Cheers,
