178 SPOLIA ZBYIiAXTCA. 



cirrus-sac (Inirsft) and vagina nierire into one another directly : 

 three testes lie dorsally and posteriorly in each segment, the 

 central one somewhat backwards : cirrus-sac very large, about 

 ;} of the cross-diameter of the body, containing a very long cirrus, 

 a uniformly thin chitinous tube coiled several times ; tlie orifice 

 of the cirrus-sac where it passes into the vagina is closely beset 

 with small equal hooks. The ovary lies unsymmetrically ventrad 

 of the vagina and cirrus-sac, a racemose body, in the centre of each 

 follicle a black granular nucleus ; vitellarixim ventral, median, 

 transversely elongate, in front of it the round shell gland ; no eggs 

 developed. 



I agree with Wolffhiigel in the opinion that the absence of 

 genital pores is not of systematic importance, and therefore the 

 species is assigned to Hymenolepis.

Intestine of the Painted Snipe, Rostratula capensis, Lin.; 

 Vavuniya. 



Length 15 mm., anterior proglottids 0'12 broad x 0*044 long; 

 hindmost proglottids greatly expanded at the hinder margin. 

 0"62 broad x 0'35 long ; all are therefore broader than long. 



Scolex thickened towards the fore-body with breadth of 0'22, 

 the foremost portion of the chain being O'll broad. 



The rostellum carries ten hooks 0*028 long ; the hooks are 

 slender and have a long root and small hook and lever ; genital 

 orifices marginal and unilateral, approximately at the end of 

 the first quarter of each member of the chain. The cirri are 

 remarkablj' large, 0*14 long, 0-018 broad at the base, closely spi- 

 nose. The broad cortical layer occupies on each side ^ of the 

 dorsoventral diameter ; a layer of transverse muscles occurs at 

 its inner side and inside these numerous small groups of longi- 

 tudinal muscle-bundles, inside these again eight stronger bundles 

 of longitudinal muscles; on each side a large ventral and a 

 smaller dorsal vessel, ectad of these, the nerve. 



The large cirrus-sac occupies nearly % of the transverse diam- 

 eter; dorsad in the middle of the proglottis, three large testes, 

 one in front beside the cirrus-sac, the two others side by side 

 farther back. The coiled vagina lies below the cirrus-sac and 

 expands to form a small receptaciilum seminis which does not 

 reach to tlie middle line ; the ovary lies in the middle third of 

 the transverse diameter, behind it the vitellarium, a transverse 

 strand of about | the cross-diameter ; the ovate shell-gland
