In the literature there is a description of a nematode Be- 

 Jetrocephalus braclujlaimus Linst. 1901 from the large intes- 

 tine of Heterohyrax mossambica Ptrs which must, probably, 

 also be referred to my new genus Kiluluma, and separated 

 from the genus DeletrocejjJialus: the facts speaking in favour 

 of this are both the brief description by Linstow, and the 

 drawing attached to his work, representing the caudal bursa 

 of the male, the arrangement of the ribs in w^hich corresponds 

 in the main features to that in Kilaluma stylosa (Lins- 

 tow 1907). 



Kiluluma stylosa (Linstow 1907). 



Host: Rhinoceros africanus. 



Occurence: stomach. 



Geographical distribution: tropical Africa. 



Description of species: 



Body cylindrical, of a yellowish brown colour, attenuating to- 

 wards both ends. Cuticle transversely striated. The cephahc extre- 

 mity is very peculiarly composed of a whole complex of or- 

 gans which may be considered under the category of a se- 

 ries of lips: exterior and interior. There are 4 exterior (peri- 

 pheral) lips: 2 dorsal and 2 ventral. Each of these lips bears 

 a peculiar papilla directed forwards and consisting of a thi- 

 ckened knobbed base on which a thinner process with a 

 rounded tip is fixed. Interiorly to the 4 exterior lips are situa- 

 ted 6 interior ones: 2 dorsal, 2 ventral and 2 lateral. Out of 

 this number of interior lips the lateral ones bear no appen- 

 dages, whereas on each of the dorsal and ventral lips is 

 situated one filiform formation with a pointed anterior apex 

 (see the medially arranged papillae in fig. 78 and text-figure). 

 The abovementioned structure of the buccal parts in this parasite 

 was left without attention by Linstow; in his work the author 

 only mentions about the presence of „4 club-shaped papillae, 

 interiorly to which are situated 4 pointed formations sitting on 

 special rounded processes". The mouth passes into the short 

 muscular oesophagus, swollen in the shape of a club in its 

 hinder part. The length of the oesophagus in the male = 0,578 mm., 

 at a width = 0,238 mm., in the female = 0,595 mm., and 

 0,255 mm. width. On the sides of the body both of the male 

 and female run wide alae gradually narrowing towards the
