Dear Graham,

Thanks for some more photos of this New Zealand endemic species. In the close-up we can see traces of the 'bumps' which cover the surface of many pleurobranchs. In the case of many 'smooth' looking species such as this species, the 'bumps' are very reduced in size.

Best wishes,
Bill Rudman
