|Abstract||(Institute of Tropical Medicine and Laboratory of Comparative Pathology and Parasitology of Leyden.) Four females 2) were collected by J. C. Wäkerlin in 1909 under the skin of a Cercopithecus brazzae, which died in the zoological garden of Rotterdam. The monkey originated from the Mid-Congo in Africa. Three of these worms were available for study, the caudal part of the fourth of them being wanting.|
The examined worms (I, II and III) are 49, 59 and 60 mm. in length.
The head-end, which has no papillae, in the 59 mm. long female is slightly swollen; near the end of the oesophagus it measures 720 µ in breadth, while the rest of the body is 510 µ broad, except the body-end, which tapers to the tail, where it is 260 µ broad in the vicinity of the anus. The cuticle is rather smooth, without transverse striations. A small mouth-opening, without lips, gives entrance to a 1 mm. long and 59 to 96 µ broad oesophagus, which is followed by a very narrow (less than 50 µ in diameter) intestine. The anus is situated at a distance of 350 p from the end of the tail, which downwards suddenly becomes thinner and ends obtusely.
The vulva in the three named worms is situated anteriorly at a distance of 1.6, 2.3 and 1.7 mm. from the anterior end of the body. It is a long and narrow aperture leading into a small chamber, from which a very short, non muscular vagina originates. The trunk of the two uteri is not very long, extending only till some 100 µ beyond the end of the oesophagus. The two uteri run parallel to each other and extend backwards at a length of 22 mm. Then one of them bends backwards, runs
