WHICH DIED In THE zoological GARDENS. 923 



The matei'ial from the Fox was dead when preserved, and 

 therefore well relaxed. 



I am of opinion that all three batches of matejial collected 

 from these three hosts belong to the same species {U. lineatus), 

 the differences between them being of a transitional or A^arietal 

 nature, or due to differences in the methods of preservation. 



With regard to the validity of the species M. litter atus ; 

 considering the extreme variability of M. lineatus, coupled with, 

 the fact that both have been recorded from the same hosts, there 

 seems to be no reason for keeping M. litteratus as a separate 

 species, especially as none of the descriptions given for it, 

 including the original by Batsch (1786) (3), contain any points 

 on which to differentiate it from M. lineatus.

In listing these three species of Inermicapsifer from the Rock 

 Rabbit (Procavia capensis) I act with great diffidence, my reasons 

 being similar to those given by Douthitt in his monograph on 

 the Anoplocephalidse, 1915 (4). 



It was only by the application of the key to the subfamily 

 Linstowinse, given by Douthitt, that I was able to make any 

 attempt to diagnose my material.

Generic diagnosis. Dipylidiinje. Rostellum armed with a 

 double crown of hooks which have a very large dorsal root and a 

 small hook portion. 



Genital pores unilateral. Genital canals pass between the 

 longitudinal excretory vessels. Cirrus pouch communicating 

 with the genital cloaca by a narrow canal opening upon a large 

 papilla. Testicles very numerous, entirely su^rrounding the 

 female genital glands. Uterus ventral, growing laterally between 

 the excretory vessels into the cortical parenchyma. 



Adults in birds and mammals. 



Type-species, Cyclorchida omalaticistrota (Wedl, 1856), Fuhr., 

 1907.
