Notes. The characteristics of this species are so marked that the figures of 
the head-outline given by Neumann make its determination definite. 
I would call attention here to the very marked sexual dimorphism in the form 
of the prothorax and in the size of the processes of the posterior lobes of the head 
(Fig. 18C). The antennae are quite distinctly four-segmented. The genitalia of 
the male are marked especially by the series of large, flat teeth which extends 
the full length of the preputial sac. The gonapods of the female (Fig. 18B) are 
simple and untoothed. Within the abdomen of the female there appears a large, 
wrinkled sac, probably a modification of the uterus, which is of a rather definite 
form, as shown in Fig. 18D. 
The association of this male and female as belonging to the same species 
seems fairly safe, in spite of the marked dimorphism. Out of all the material 
examined there seems to be no other species to which either might possibly be 
referred. 
Trichodectes lindfieldi Hill

1922. Trichodectes lindfieldi Hill, Parasitology 4: 65-67; pl. 2, figs. 4-6. (As to the male.) 
1928. Trichodectes lindfieldi Hill, Bedford, Report Director Veterinary Education and Research, 
Union of South Africa 13-14 : 845. 
Previous Recorps. Recorded by Hill from Procavia capensis, Mtabam- 
hlopi, Natal. 
Present ReEcorp. From Procavia adolfi-friederici, Lulenga, BrLGIAN 
Conao, March 2, 1927 (J. Bequaert), and from Dendrohyrax validus, Mt. Kali- 
manjaro (United States National Museum). 
Nores. In the original description of this species Hill has undoubtedly asso- 
ciated the male and female of different species. I here designate the holotype 
as a male, ‘no original designation having been made. The female belongs to a 
species which is at hand and which I am identifying as 7’. sternatus Bedford. 
The species is well marked by the rather peculiar form of the head, by the 
apparently entire absence of the pharyngeal sclerite, by the short, but very 
definite, processes on the posterior lobes of the head, the spinose-serrate claws 
of the middle and posterior legs, the genitalia of the male and the gonapods of 
the female. 
The genitalia of the male (Fig. 204) have the preputial sac beset with a num- 
ber of large, flat teeth near its posterior end. The female has the gonapods 
(Fig. 20H) beset with a distinct, somewhat fimbriated, lobe on the inner face.
