ART. 10 



EARTHWORM FAUNA OF BURMA — GATES 



19 



The spermathecal pores are four pairs in 5/6, 6/7, 7/8, and 8/9. 

 There are 15 setae between the lines of the spermathecal apertures 

 on viii. 



The genital papillae are paired on vii, viii, and xix. On xx there 

 is a single papilla on the right side just behind the papilla on xix. 

 There are 4 setae on vii and viii between the centers of the papillae. 

 There are 13 setae on segment xLx between the centers of the 

 papillae. The markings are small, round, and are located between 

 the setae and the anterior furrow of the segiment. Each papilla 

 consists of a gray concave spot surrounded by a definite whitish rim 

 or lip. 



Internal anatomy. — 4/5 and 5/6 are thin, 6/7 and 7/8 are slightly 

 thickened, 8/9 is represented only by a ventral vestige attached to 

 the longitudinal sheet of tissue underneath the gizzard, 9/10 may be 

 partially fused with 10/11 or is absent, 10/11, 11/12, 12/13, 13/14, 

 and 14/15 are very slightly thickened. 



The length of the gizzard is slightly greater than the diameter. 

 The intestine begins in xvi. Intestinal caeca extend from xxvii into 

 xxiv. The last pair of hearts is in xiii. 



The anterior testis-sacs are large and apparently lie within septum 

 10/11, but this septum may represent a fusion of 9/10 and 10/11 

 except where separated by the testes. A large portion of segment xi 

 Is shut off by connective tissue in such a way as to form a testicular 

 chamber within which are enclosed the testes, and male funnels, the 

 seminal vesicles, the alimentary canal, and the commissures. The 

 seminal vesicles of xii are small, although larger than the vesicles of 

 xi and are attached to the posterior face of 11/12 at the sides of the 

 alimentary canal. The prostates are highly lobulated glands extend- 

 ing through xvii-xLx. The prostatic duct is about 1)4, nim. long and 

 is slightly looped. 



The ovaries and oviduct funnels are in xiii as usual. The sperma- 

 thecae are in segments vi-ix and open anteriorly. 



Distribution. — Lashio and Maymyo, F. S. S. 



Remarlcs. — The length, diameter, and segmental numbers vary only 

 slightly as the figures below, of five worms chosen at random, show; 



The first dorsal pore is in 12/13 in all the specimens.
