The head isrounded, but lips obvious, and papillae were are observed; at its no no base the openings of the large lateral organs are situated; they are seen in profile in the figure 10. The spear is long and, as usual, it is possible to distinguish two parts, which are, in the species under con- sideration, of exactly the same length. According to the figure of DE MAN, the proximal part is in the European form, at any rate in the specimen figured, inconsiderably longer than the distal part. The two parts are very different in structure; the distal half consists of the proper spear, strongly chitinized on and thick-walled, the lumen in its interior is obvious but very narrow, and the apical opening is found GH the side immediately behind the tip. The proximal half is relatively weakly chitinized, and the lumen in its interior is increasing towards the base; it is provided with three projecting wings of a somewhat other shape than in the European species, the difference being easily seen, when comparing my figure with the figure of DE MAN (Pl. XXVI, fig. 110 a) in his great monograph of the Dutch free-living Nematodes (1884). The distal half is, as in the European species too, surrounded by a sort of sheath or gubernaculum, which is presumably able to manage the movements of the long spear.</paragraph>
