| Abstract |
High species richness for shell-bearing Mollusca was found in a thanatocoenoses in upper bathyal bioclastic sands of the Coral Patch Seamount. 142 molluscan species have been identified of which only 18 bivalves, 119 gastropods, four scaphopods and one placophoran. The molluscan fauna can be characterized as unique: deep marine without significant influx from shallowwater or Mediterranean Sea species. A significant number of unknown species have been encountered but only six new species have been described in this paper: Basilissopsis vanheugteni n. sp., Ancistrobasis lavaleyei n. sp., Papuliscala lydiae n. sp., Fusceulima coralensis n. sp., Fusceulima victorhensenae n. sp., Chrysallida intorta n. sp. The remaining, unknown species are considered too difficult to uniquely describe because the associated material was of poor quality, inadequate quantity or with an ambiguous morphological variability at species level. |
