ampulla and one- third as thick ; the diverticulum is single, club- 

 shaped, and attached near the ental end of the duct on its inner 

 side ; the spermatic chamber is single. The length of the diverti- 

 culum is less than that of the ampulla. So far as can be made out 

 internally, the external openings of the spermathecae would be 

 between the setal line and the anterior border of segments viii and 

 ix respectively. 



The length of the penial setae (fig. 23, a and h) varies, "87 — i 

 mm. ; the thickness at the middle is i^i*- ; they are thus of very 

 considerable length relatively to their thickness. The main part of 

 the shaft has only a slight curve ; but the curve of the distal end 

 varies somewhat, so that two types can be distinguished. In the 

 first, the curve of the distal end merely continues the curve of the 

 shaft, and the tip is tapering and bluntly pointed ; a few teeth, of 

 moderate size and fairly closely applied to the shaft, are present 

 some little distance above the tip. In the second, the distal end 

 is considerably bent, it may be to nearly a right angle ; the tip is 

 thinned and rather expanded, and in a few almost spatula-like, 

 the end being also less clearly defined and slightly bifid ; the 

 teeth are more numerous. The shorter length given above repre- 

 sents the first type, the longer the second. 



The copulatory setae (fig. 24) belonging to segments viii and 

 ix are •61 mm. long and 20/ in thickness at the middle of the 

 shaft The shaft is bowed, at the ends more so than in the middle. 

 The distal portion of the shaft, — almost half, — is cut up along 

 both its convex and concave borders into a series of rough not- 

 ches, seven or eight on each side, and a thin web appears to span 

 each notch. The tip is rather claw-shaped, and bluntly pointed.
