039087B39278433EFCB3F300FF4CF9C4.taxon	discussion	REMARKS The species Sluiterina sibogae is known from a single female from Indonesia collected at a depth of 4391 m. Although the present specimen is much smaller in size, it approaches the description given by Sluiter (1902) especially in the structure of the proboscis. According to Sluiter (1902) the proboscis is Thalassema - like with the lateral edges close together giving it a tubular appearance. Similarities are also evident in the distribution of the dermal papillae. Unfortunately, the anal vesicles have not been described by the latter author. In the specimen from the North-East Atlantic there is a single gonoduct with a basally located gonostome. All the other species in the genus Sluiterina differ from the specimen on hand in possessing anal vesicles that are bushy, consisting of numerous, thin, unbranched excretory tubules resembling a string mop.	en	Biseswar, Ramlall (2005): Report on some deep-sea echiurans (Echiura) of the North-East Atlantic.
