Body robust anteriorly, progressively slenderer in posterior 2/3. Cuticle with fine transverse striations, the alae in addition to these transverse striations having a lonm- tudinal line dividing them in two halves, the outer half more deeply colored. Two papillae at anterior insertion of alae. Mouth (fig. 270#) with 2 tri-lobed lateral lips, the median lobe having a small tooth, the lateral lobes a finelv denticulated edge. Length of esophagus 1/7 that of the Fig. 270.—Hartertia rotundata. a, Head, ventral view ; b, male tail. Sbubat, 1914 Aft etc Male 35 to 37 mm. long by G60/* wide. Caudal alae (fig. 270&) symmetrical, mm. long by 720/u, wide. Six pairs of long pedun- culated papillae, of which 4 are preanal, in addition a group of 5 pairs of small papillae in the region of the caudal extremity. Ven- tral surface covered with protuberances. Cloacal aperture 540ti from tail end. Spicules unequal, mm. and 450/* long. Gorgeret present. Female 35 to 66 mm. long by 900/* wide at a level of alae. Cephalic papillae 70/u, from anterior end. Tail long, mm. in a 35 mm. speci- men. Vulva posterior to anterior third of body.
