I am currently working on the compilation of the first volume of the IUCN Red Data Book for invertebrates with special res ponsibility. for non-insect groups. Following its publication I hope to be working oO a more specialised volume for molluscs. Initially I nad not expected to find any information on threatened opisthobranchs.

The closure of tne Zuiderzee caused its disappearance from most known localities, including its type iocality, and it may now be extinct. DESCRIPTION The shape of the mantle which is eomplete at the posterior end of the animal separates this species from its nearest relative, C. sargassicola from the Sargasso Sea (1). -A small sea slug reaching only about 5mm in length, C. batava is variable in colour, ranging from yellow with black patches to dark brown or black all over. it has a circular dise-shaped mantle and a flat, almost circular foot (4). DISTRIBUTION Endemic to Holland. The type locality is at Durgerdam near Amsterdam beyond the River Ij. It has been recorded from the coasts of the former Zuiderzee from Amsterdam to Den Helder in many-localities (1 ), including Wieringen on the Vangdam and near ue ede in Texel ee Aye" POPULATION Unknown. BABITAT AND ECOLOGY Found in brackish water generally in salinities from 7-25%0, but. it. can probably withstand salinities up to 30%0 since large numbers have oeen found in Den-Helder narbour. The lowest salinity in which it has oeen found is 6.740. It is restricted to shallow water on or near Cordylophora caspia on which it may feed; it has also been found on Membranipora (1,2). SCIENTIFIC INTEREST AND POTENTIAL VALUE THREATS TO SURVIVAL The closing of the Zuiderzee resulted in the disappearance of all the brackish water fauna in the area, and C. batava is almost certainly now extinct and a definitely extinct in its type locality (1). The Zuiderzee was closed in May 1932, following which this species continued to be found in the northern part of the enclosed area untii Juby- of that year since when it has not been found there. 1947 it was recorded at Texel (2). OPISTHORANCH NEWSLETTER | CONSERVATICN MEASURES TAKEN None. CONSERVATION MEASURES PROPOSED It could possibly still. survive _in the harbour at Den Helder or in brackish water on some of the Wadden Sea Islands, such as Texel. However both these areas are severely polluted. Itis also conceivable that the species may be found in France or England (5). Surveys should be earried out in the Wadden Sea and Den Helder harbour to ascertain if this species is still | extant. If it is found, steps should be taken to ensure that it is protected in a suitable _ wunpolluted area of brackish water. REFERENCES 1. BUTOT, L.J.M. (1977).

Bor the most part, weather was perfect with zlassy seas and clear visibility. Our entire operation came up with a rather disappointing 48 species ~ oo of which we collected during 6 days in May during extreme Low, dawn tides in the sieeetiaal especially around the rocky islands. Some findings, however, should be enough to intrigue the biologically oriented opisthobranchologist: 1. For the first time in tne easter Pacific we have found a cryptobranch dorid parasitized by an internal copepod quite different from literature reports. 2. California’s Flabellinopsis iodinea is our most colorful aeolid. This survey provided a startling look-alike not even in the same family. 3. Anew aeolid that appears to feed exclusively on a symbiotic nydroid growing on the back (dorsum) of a small, under-rock was found. A similar case has been reported from the northwestem Atlantic. 4. Tambja adere vs. Tambja fusca: separate or the same species? Ever since Farmer (1975) described this (these) animals from the northern Panamic the valicity of two species has been questioned. theses trips we were able to obtain more than a nundred specimens and study them in life. I would expect the results of this inquiry to satisfy most taxonomists. None of this work could have been carried out without the help of expecially dedicated persons.
