The narrow anterior lobes of the lips (fig. 1, a.) are sharply notched on their inner surfaces, that of the dorsal lip being thus divided into two equal portions. The notch of each ventro-lateral lip, however, divides the lobe asymmetrically, the portion ventral to the notch being larger than the latero- dorsal portion. The anterior lobe of each lip carries a denti- gerous ridge with very coarse, rather irregular teeth. The basal portion of each lip bears two papilla3. Those of the dorsal lip are lozenge-shaped, double papillae, while each Fig. Anisahis physeteris^ female. The lips, viewed en face. a., anterior lobe, and d., basal portion,-of dorsal lip; e., excretory pore; , papillae. ventro-lateral lip has one papilla of this type towards its ventral side and one very minute, sim})le papilla situated more laterally and further forward. There is a pair of cervical papillse, situated at a distance of about 1 mm. from the anterior end. The muscular portion of the oesophagus measures about 6 mm. in length in the male and 7 mm. in the female. It has a maximum thickness of a little over 1 mm. There is a very short ventriculus or glandular portion of the oesophagus.
