Th(> ;ibdomeii is eylindric nearly its entire length; ])os- teriorly it is slightly reduced at its junction with the foot, which has two joints of nearly e(]uai length. The toes are short, about one twentieth of the entire length, bl:ule-sh.Mi)ed and slightly decurved, with slender, acute i)oints. The corona is terminal; the lateral, marginal cilia are somewh.at longer than the rest and form rudimentary auricles. The dorsal anteinia is a small, ciliated pit in the normal position; the lateral antennae are on the i)osterior fourth of the abdomen. The trophi are forcii);tte and of a rather umisual type. The rami are of the normal lyrate form, terminating in a strong, pointed tooth; on the inner etlge, about mid-length, there is an additional fairly large, pointed tooth. The fulcrum is unusually well (h'veloi)ed, its h'Ugth being fully cpial to the length ot t!u- rami. Till' linci are .'ibcrrant; a sinpir, sliort and robust tooth, hinged to the ranms at mid-length on a knob-like ei)iphysis, ai)i)ears to represent th(> uncus i)roper; it is connected to the manubrium through a rather slender bar, enlargeil at the i)osterior end, and nearly as long as the tooth itself.
