Abstract

and The second author discovered the species described here while conducting a sabbati- cal research project on benthic microbial mats and submarine ground-water dis- charge off Key Largo, Florida (Fig. 1) (Sim- mons et al., 1985; Simmons and Love, 1987). Numerous pencil-sized holes, ringed by a cone of sediment, were observed and originally believed to be associated with the submarine ground-water discharge phe- nomenon. Sagittal core sections showed the holes to be unlined, to have extremely jag- ged and irregular walls, and to have the opening often occluded with flakes of Hal- imeda and/or other bits of sedimentary ma- terial (Fig. 2). The core sections suggested small dissolution channels rather than the work of an invertebrate. At the suggestion of Mr. Joe Dobarro (New Jersey Bureau of Shellfisheries, Bi- valve, New Jersey), the second author in- jected a mixture of ink and sea water into the holes, and eventually demonstrated that the holes were clustered, even though gen- erally abundant across the bottom where they occurred.
