This form was first noticed in a small aquarium belonging to Mr. Sibert Saunders, at Whitstable, in 1884, and he kindly forwarded living specimens to the St. Andrews Marine Laboratory for examination. It is about 8 or 9 mm. in length by 1 mm. in breadth, including the bristles. The number of segments varies on each side of 30, exclusive of those without bristles. It is characterised by a horseshoe-shaped head furnished with a pair of short dorsal tentacles of two segments, and a similar pair on the ventral surface. Four eyes occur dorsally, one on each side behind the dorsal tentacle, and a smaller pair just in front of the nuchal fold. Each foot has dorsally a short cirrus, and ventrally a somewhat larger one, besides a long process of the setigerous region. Dorsally are long simple bristles, inferiorly bristles with an articulated terminal piece. The jaws consist superiorly of a pair of curved maxillae and about six small dental plates on each side. The anterior edge of these in ordinary views from above is minutely denticulated. The mandibles present a crown and anterior projection. This form comes nearest the Staurocephalus minimus of Langerhans 1 from Madeira.
