Blanchard, 1891: Strobila attains 130 mm. in length, 15 mm. in breadth, 2.5 mm. in thickness; contains about 400 segments. Head subspherical, 0.G5 mm. broad by 0.01 mm. long; suckers oblong, 0.34 to 0.345 mm. long by 0.27 to 0.28 mm. broad, two arranged on dorsal surface, two on ventral surface. Neck very short (0.3 mm.); about as broad as head. Segments always much broader than long; maximum breadth 15 mm. at 45 mm. from head, maximum length about 0.35 mm. Genital pores very small, lateral, alternating very regularly. Male organs:1? Female organs: Glands? Uterus in fully developed stage composed of 30-35 polyhedral packages, 0.5 to 0.9 mm. by 0.1 to 0.8 mm., arranged in transverse row, occupying entire breadth and thickness of segments. Ova 53 to 00 //, pyriform body 14 to 10 p broad, 23 to 30 yu long, horns generally straight, oncosphere 10 to 12 ju. Cortical layer of strobila supplied with numerous calcareous corpuscles 15 to 20 /a by 11 to 17 p. Rost.—Chimpanzee (Anthropopithecus troglodytes (Linnaeus) [Troglo- dytes niger]), by Studer.

Blanchard, 1891: Strobila attains 245 mm. or more in length by 10 mm. in breadth by 2 mm. in thickness, and contains about 350 segments. Head and neck unknown. Segments always much broader than long, attaining a maximum length of 0.75 mm. Genital pores very small, lateral, irregularly alternate. Calcare- ous corpuscles numerous, attaining 30 by 20 ja. Dorsal canal lateral of ventral canal. Cirrus-pouch claviform, large and elongated. Uterus resembles somewhat that of B. studeri. Ovum 35 to 38 ]a by 30 to 32 yu, pyriform body 12 to 17 ja by 19 to 25 yu, oncosphere 13 ja. Rost.—Oran-Utan (Simia satyrus, Linnaeus). Type.—Leyden Museum. From these descriptions it is impossible to come to any satisfactory conclusion as to whether the genera Andrya and Bertia should be kept separate or united. The form of the segments must surely be rejected as a generic character, and the fact that the pores of Bertia show a tendency to appear regularly alternate while those of Andrya show Proc. E.
