ABT. 10 EARTHWORM FAUNA OF BURMA GATES 11 



The genital markings are small, nearly round, whitish elevations 

 with a grayish spot at the center. They are located on segments 

 vii, X, xi, and xii. Those on vii lie in contact with 7/8 in line with 

 cd, on each side. The papillae on x are in he about equidistant from 

 l and c, and are in line with the eight setae of the segment. The 

 markings on xii are in he, in line with the papillae of x but are on 

 the anterior border of the segment in contact with 11/12. There is 

 a single median papilla in aa on xi, in contact anteriorly with 10/11. 



Internal anatomy. — Septa 5/6, 6/7, 7/8, and 8/9 are thickened. 



The four gizzards are in segments xix, xx, xxi, and xxii. 



The last pair of hearts is in segment Lx. 



The large testis sacs are in Lx and x, constricted by 9/10. The vas 

 deferens is coiled into a small mass on the posterior face of 10/11, 

 under the testis sac of each side. The prostate is bent into a 

 horseshoe shape, with the opening toward the nerve cord and the 

 posterior limb passing into the parietes. The vas deferens passes 

 into the end of the 

 anterior limb. 



Segment xi is re- 

 duced to a small 

 closed chamber. The 

 ovisacs extend into 

 XV. The spermathe- 

 cal ampulla is large

is coiled into a small 



mass on the posterior face of 7/8 immediately under the ampulla, 



and is looped as it passes from the ampulla along the septum to the 



parietes. The atrium in vii is finger shaped and stands erect in the 



segment. 



Distribution. — Kyundo, Kawkareik (October). 



Remarlcs. — The length varies from 80-110 mm., and the diameter 

 from 33^-4 mm. at the posterior end to 43/^-53/^ mm. at the ante- 

 rior end. 



The male pores of most of the specimens are at the tops of slight 

 conical elevations on 10/1 1 . The spermathecal pores are in line with 

 c or d, just internal to c or just external to ^7. 



The four gizzards are in xviii-xxi, xix-xxii, or xx-xxiii. 



The prostates are coiled or bent into various positions. 



The small round genital papillae occur on segments vii-xii. They 

 are paired in he on the anterior or posterior borders of the segments. 

 Unpaired median papillae occur in aa, on the anterior, middle, or 

 posterior thirds of segments vii, ix, x, and xi. 



The atria are often bent at various angles.
