Nygolaiius hartingii (deMan) nom. nov.

Sixteen specimens of this agile, little predacious species are in the collection. They correspond very closely to the European form described by deMan under the name Dorylaimus hartingii ( 5), which has been found to belong to the Genus Nygolaimus ( 9).

Transverse striae excessively fine. The lip region is almost continuous with the body contour and bears two circlets of obscure papillae. Tooth as long as the width of the lip region. Posterior three-fifths of the esophagus enlarged but irregular in diameter. There are three conspicuous glands located at the cardic constriction. A pair of long slender organs are located dorsally in the body and these crowd the anterior end of the intestine. Fig. 9 b. The symmetrical ovaries are reflexed nearly to the vulva. Eggs two-thirds as wide as the body and two and one-half times as long as wide. Prerectum about three times as long as the rectum. The acute, ventrally bent tail is characteristic of this species.
