The ovaries and oviduct funnels are in the usual positions in seg- 

 ment xiii. The spermathecal ampulla is large, flattened out dorsally 

 by the gizzard. The duct is short and practically confined to the 

 body wall. The single diverticulum is on the outer side of the duct 

 and consists of four elongate, finger-shaped seminal chambers placed 

 side by side. 



The parietes are thickened in the region of the median genital 

 markings. 



Distribution. — Meiktila (October) . 



Remarks. — The length varies from 190-280 mm. The first dorsal 

 pore is in 11/12 in all specimens. The clitellum begins just anterior 

 or just posterior to the setae of xiii and extends to 17/18. 



Setal intervals ab and cd vary somewhat, ab and cd usually equal, 

 but in some specimens ah is noticeably smaller than cd. Interval aa 

 is larger than be on all the worms. 



On several of the specimens there is a minute depression on seg- 

 ment xiv, where the female pore of the right side would ordinarily be 

 located, but no actual pore can be seen. 



The genital markings are quite characteristic » 

 just one worm from a large number differing from 

 the type. In the exceptional specimen there is a 

 third genital papilla, about the same size as the 

 posterior marking, located between the setae of 

 segments xiii and xiv.

anterior end. 



The prostatic duct is 14-16 mm. long. 



The spermathecal ampulla is variously shaped and often consists 

 of three to seven elongate seminal chambers arranged as in the type 

 specimen. Frequently the chambers are round, more numerous, and 

 so arranged on the free end of the diverticulum as to produce a berry- 

 like appearance. 



The penial setae are 4-5 mm. long, 46-54 micra thick near the 

 base, and 48-52 micra thick near the tip. The shaft has two long 

 curvatures, the concavity of the first half of the seta on the opposite 

 side from the concavity of the second half. The ornamentation 

 consists of short rows of three to five teeth, or of single teeth scattered 

 over the first 0.8-0.9 mm. of the tip.
