Figure 18.—Berndtia fossata, new species, from Psammocora fossata from eastern New Guinea: a, sketch of surface view of opercula, with detail of margin; b, mandible; c, first maxilla. The body is almost exactly the same as in the other species of the genus, as far as can be ascertained. There are five pairs of terminal cirri without a caudal appendage, plus a prominent mouth cirrus with six and five segments in the anterior and posterior ramus, respectively, on a two-segmented protopod. The mouthparts are typical (figure 18b, c). The mandible has three major teeth plus an inner angle with numerous fine teeth and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; Smithsonian Institution; United States.
