slender. The remaining three pairs form a 

 group on either side of the sucker, decreasing 

 in size from behind forwards. The most 

 posterior of these three pairs is very mas- 

 sive. The length of the tail {i.e., from the 

 cloaca to the posterior extremity) is about 

 cn.3 mm., of which the terminal spike 

 measures o*o6 mm. 



In the female the short, conical tail 

 measures 03 mm. in length, and bears a 

 pair of small papillae at 0*14 mm. from the 

 tip. The vulva is situated at 3*0-3 3 mm. 

 from the posterior end. The vagina is long, 

 slender, and pursues a rather tortuous 

 course, the general direction of which is 

 posterior from the vulva. The branches of 

 the uterus are parallel, running at first 

 posteriorly to within a short distance of the 

 anus, then returning towards the anterior 

 end. The coils of the ovaries are situated in 

 the anterior half of the body. The eggs are 

 oval, with a thick shell, slightly flattened 

 externally and thickened internally at each 

 pole. They measure about 0*0875 x 0*055 



mm. When ready for laying the content of the egg is still unsegmented and coarsely 



granular. 



Of the species referred to the genus Strongylu- 



ris, two, S. sonsinoi (v. Linst., 1894) and S. elegans 



(Gendre,. 1909), occur in chamaeleons, the former 



in the same chamaeleon as the present species. S. 



sonsinoi, however, differs widely from our form, 



and from all others except S. campanula (v. Linst., 



1899), in the elongate and conical shape of the tail 



in the male and in the possession of small, sessile, 



caudal papillae instead of the typical elongate, 



ray-like papillae. The present species is more 



closely related to S. elegans, but differs from it in 



its smaller size and the much longer spicules of 



the male, besides other details ; and we are equally 



unable to identify it with any of the known species 



parasitic in lizards. 



As regards the systematic position of Strongyluris, Seurat
