has three or four large lobes marked off by deep incisions and each 

 lobe is composed of several lobules. The duct is S-shaped and vari- 

 ously placed. Near the prostate on each side is a single gland with 

 a duct which passes into the body wall and opens to the exterior 

 through the pore on the tip of the papilla on xviii near the male pore. 



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

 ment xiii. On the posterior face of 12/13 at each side of the intestine 

 is an elongate club-shaped structure that may be an ovisac. The 

 two pairs of spermathecae lie in combination gizzard segment and 

 open anteriorly. Near each spermatheca is a single glandular mass 

 with a duct similar in appearance to the glands located near the 

 prostates. 



Distribution. — Lashio, F. S. S. 



Remarks. — The length of other specimens varies from 120-140 mm., 

 and the diameter from 5-6 mm., at the posterior end, and 7-8 mm., 

 at the anterior end. 



The posterior furrow at the end of the prostomial tongue on segment 

 i is lacking on all but one of the worms. 



Two secondary furrows may be present on any segment posterior 

 to V. 



The first dorsal pore is in 11/12 in all of the worms. In many 

 specimens the positions of the dorsal pores on the clitellum are 

 indicated by pore-like depressions in the thickened epidermis, but in 

 none of these worms are there functional pores on the clitellum. 



The setal circles are usually without a ventral break; the dorsal 

 break is small, about 2 yz. The setae are located on distinct ridges. 



The papillae bearing openings of the ducts of glands of the pro- 

 static region are usually absent and when present vary in number. 

 Three specimens have a pair of such papillae as in the type. Two 

 have two pairs, the second pair posterior to the setae. One worm 

 has one papilla on the right side. The pore bearing papillae are 

 placed so as to occupy the entire space between two consecutive 

 furrows on the slope of the conical swelling. 



The number of setae between the male papillae varies from 18-24, 

 21 the number most commonly found. The number of setae on viii 

 between the Hues of the spermathecal pores varies from 23-28, 24, 

 25, or 26, the numbers most commonly found. 



Setae from various dorsal and ventral positions anterior to the cli- 

 tellum and various ventral positions posterior to the clitellum were 

 examined microscopically. All such setae have ornamented outer 

 ends, the ornamentation consisting of short transverse rows of very 

 fine teeth. 



The last 10 septa are much thickened in all specimens examined. 



The ventral edges of the intestinal caeca are incised or lobed in 

 such a way as to form ventrally projecting secondary caeca. The
