By Ernst Kirsteuer 2 



This paper is based on collections made by the author on Dominica, 

 B.W.I. , during April 1966 from Middle Bay below the village of 

 Marigot on the northeast coast of the island. Two species of archian- 

 nelids, Saccocirrus archboldi, new species, and Protodrilus corderoi 

 Marcus, were found when sand samples were examined for psam- 

 mobiontic nemerteans. Substrate samples were taken to a depth of 

 100 mm in the middle of the inter tidal region and also from near 

 low water line of the sandy beach. The substrate samples were 

 placed together with sea water in pails, and after two to three days 

 the surface layer of sand was examined for specimens with a dissecting 

 microscope. In the samples from the midintertidal zone, both
