In tlie male the tail (fig. 3) is 07 mm. long. The spicules 

 are of equal length (T9 mm.), and are alate, measuring 

 about, 0*07 mm. in width. There are thirteen pairs of caudal 

 papillae — five postanal, one large adanal, and seven preanal. 

 The preanal sucker (fig. 3, su.) measures 0'25 mm. in 

 diameter. The body is somewhat compressed laterally in the 

 region of the sucker, and the cuticle raised ventrally into two 

 longitudinal ridges (fig. 3, r.) at the sides of the sucker. 

 These ridges perhaps represent caudal alas. 



In the female the tail is 1*25-1*6 mm. long. The vulva is 

 situated very slightly in front of the middle of the body. 

 The vagina and unpaired portion of the uterus are short, and 

 together form a tube which runs forward in a sinuous course 

 for about 2 mm., before giving off at right angles the two 

 uterine branches, which run perfectly straight forward and 

 backward respectively. The ova are of oblong-oval shape, 

 with a thick shell, and measure <S8 /* X 45 /a. 



2. Subulura loveridgei, sp. n. (Fig. 4.) 



Host : (?) Mangos \_Crossarchus] fasciatus. 



Locality. (?) Morogoro. 



This is a slender little worm, which occurred in very large 

 numbers. The identification of the host, unfortunately, is 

 somewhat doubtful, owing to the loss of the collector's label, 

 but Mr. Loveridge believes that it was that named above. A 

 species of Sabulura is already known from a closely-related 

 host (S. schebeni, v. Linst., from Cynictis penicillalci), but 

 the present species is considerably larger. 



The largest specimens measure: male 19 mm. long and 

 0*52 mm. thick, female 29*7 mm. long and 0*65 mm. thick. 

 There are no cervical alas. The oesophagus, including the 

 posterior bulb, measures 1*75 mm. in length from the anterior 

 extremity in the male, and 2*15 mm. in the female. The 

 bulb is distinctly marked off by a constriction, contains a 

 chitinous denticular apparatus, and measures 0'3-0'35 mm. in 

 length. The nerve-ring is situated at 035 mm. from the 

 head-end in both sexes, and the excretory pore at 0'625- 

 0"65 mm. 



In the male the caudal end (tig. 4) is provided with a 

 ru limentary preanal sucker (fig. 4, su.). The tail itself 

 measures 0"37 mm. in length. There are ten pairs of papillae, 

 of which seven are postanal. The second and seventh pairs 

 are situated more laterally than the rest. The two equal 

 spicules (tig. 4, sp.) measure 1*55 mm. in length. At the 

 proximal. end they are simple and tubular, but at about
