ART. 10 EARTHWORM FAUNA OF BURMA GATES 27 



are absent; 8/9, 9/10, and 10/11 are much thickened and displaced 

 backward together; 11/12 is represented only by thin connective 

 tissue which forms the median testicular chamber. The remaining 

 septa are thin and attached normally. 



The gizzard is bell-shaped with a posterior flange. There are 

 calciferous glands in the wall of the alimentary canal in segment xii. 

 The intestine begins in xv. 



The supra-pharyngeal and sub-pharyngeal ganglia are bright yellow 

 but the circum-pharyngeal connectives, the nerves, and the ventral 

 nerve cord are whitish as usual. 



There are large tufted masses of nephridia adherent to the parietes 

 in segment iii. 



There are two pairs of vascular commissures under septum 8/9. 

 The last pair of "hearts" is in segment xiii. The commissures of xi 

 lie within the testicular chamber on the posterior face of 10/11. 



The testes and male funnels are included within the median 

 testicular chamber. The seminal vesicles are in contact with 10/11 

 anteriorly and posteriorly push 12/13 back into contact with 13/14, 

 The prostates are in xviii-xx, and are tubular. The ducts are in xvii 

 and are coiled into an S shape. 



The ovaries and oviduct furmels are in the usual positions in 

 segment xiii. The spermathecal ampulla is elongated in the direction 

 of the main axis. The duct is very short and almost entirely 

 confined to the body wall. Each spermatheca has two diverticula, 

 one on each side of the duct. The diverticula consist of three to 

 seven seminal chambers arranged together as an elongate row or as 

 a club-shaped body, and are nearer together posteriorly than 

 anteriorly. 



There are glandular thickenings of the ventral parietes in the 

 region of the anterior and posterior genital markings. 



Distribution. — Mandalay. 



Remarks. — The length of the other specimens varies from 180-245 

 mm., and the diameter from 6-8 mm. 



The first dorsal pore is usually in 17/18, rarely in 13/14, although 

 nonfunctional porelike depressions occur between 10/11 and 17/18. 



The clitellum begins at 12/13 or somewhere between 12/13 and 

 13/14 and always extends to 17/18. 



Two worms have a genital marking on 14/15 between setal lines 

 aa, w^hich is light in color, concave, but not as sharply delimited as 

 the other two similar areas. 



The typhlosole begins in the region immediately behind the clitellum 

 and ends 65-70 mm. from the posterior end of the worm in the region 

 of the supra-intestinal glands. These glands are 12 pairs, 2 pairs in 

 each of 6 successive segments. 



The oviduct funnels are small and have thick rounded rims.
