On a trip to Pakistan in 1968 Professor Sebasian-Adam Gerlach of Bremerhaven, collected ten onchidiids and three arminids. Professor Richard L. Miller, Temple University, Philadelphia, photographed and preserved a doridid at Newport Bay, California. Dr Gale Sphon, Los Angeles County Museum, sent five specimens and a number of kodachromes of a colourful chromodoridid collected on the Mexican coast. I thank these gentlemen for the opportunity to study their precious material.
