ART. 10 EARTHWORM FAUNA OF BURMA — GATES 9 



Segments vii to xiii have a secondary furrow posterior to the setae 

 of the segment. Segments x to xiii have a second furrow anterior 

 to the setae of the segment. Most of the segments posterior to the 

 chtellar region have two slight secondary furrows to each segment, 

 one anterior to and one posterior to the setae of the segment. 



There are pore like depressions in the intersegmental furrows from 

 4/5 posteriorly, but apparently no functional dorsal pores. 



The setae begin on ii, and are closely paired; ab is equal to cd, aa 

 is less than be, and dd is about one-half of the circumference. 



The clitellum is on x-xiii (4). 



The male pores are on the conical papillae on 10/11, and arc slightly 

 external to b. 



The female pores are in 11/12 and are in line with b. 



The spermathecal pores are in 7/8 in the region of cd. 



The most conspicuous genital marking 

 is the conical papilla on each side of the 

 worm in the furrow 10/11. The inner 

 edge of the papilla is internal to b. The 

 papillae are bent slightly toward each 

 other and are constricted slightly at the 

 base by a circumferential furrow and bear 

 at the tip the male pores. Posterior to 

 the setae of x and extending to c on each 

 side is a transversely elongate depression, 

 slightly deeper at each end than in the 

 middle. On each side of xi, posterior to figure 2— drawida constrict a. 



,1 , 1 • T -xu au 1 External view of ventral geni- 



the setae, and in line with the male poro- ^^^ region 

 phore is a slight depression. On segment 



xii, behind the setae, and extending slightly beyond b on each side is 

 an oval, concave, glandular like area, sharply delimited by a circum- 

 ferential furrow. 



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



There are two gizzards in segments xvi and xvii. The wall of the 

 alimentary canal is slightly thickened in xv. 



The last pair of hearts is in ix. 



The testis sacs are ovoid bodies in ix and x, half in each segment. 

 The vas deferens is a small coiled mass on the posterior surface of 

 9/10, under each testis sac, and passes into the middle of the prostate. 

 The prostates are small dome-shaped bodies on the parietes. The 

 surface is coarsely granulated. 



The ovarian chamber is closed dorsally just over the alimentary 

 canal. The ovisacs extend into xv. The spermathecal ampulla is 

 large and ovoid on the posterior face of 7/8. The duct is fine and is 

 coiled into several loops. 



Distribution. — Mandalay, Prome, Thayetmyo.
