AET. 10 EARTHWORM FAUNA OF BURMA GATES 37 



species of this genus. The tail portion of the worm was doubtless 

 amputated some time prior to the time of collecting and the broken 

 end was healed over without producing new segments to replace the 

 lost ones. Shorter fragments of the same species are the only other 

 specimens included in the present collections. 



The first dorsal pore is in 11/12. The clitellum begins just poste- 

 rior to the setae of xii, at 12/13, or just anterior to the setae of xiii. 



Setal interval aa varies from one and one-half to two times he. 



One specimen has a small oval marking on xiv in aa just behind 

 the setae. Another specimen has a large oval marking on xii in hb, 

 just behind the setae. 



The prostatic duct is 7 to 8 mm. long. 



The penial setae are 3 mm., or less in length, 48-50 micra thick 

 across the tip, 25-28 micra thick at the narrowest point just behind 

 the tip, and about 40 micra thick at the inner end. The tip of the 

 seta is flattened out into a wide spatulalike structure. The orna- 

 mentation begins on the flattened portion, extends along the shaft 

 for about 0.3-0.4 mm., and consists of numerous irregular and broken 

 ridges of jagged teeth. 



EUTYPHOEUS SIMILIS, new species 



Description of the type-specimen, external characteristics (Gates col- 

 lection). — Length, 177 mm. Diameter, 4-7 mm. Number of seg- 

 ments, 229. Color: Unpigmented, light greyish white, except on the 

 clitellum, which is reddish brown. 



The prostomium is prolobous. 



On segments iv-xii, inclusive, there is a deep secondary furrow 

 posterior to the setae. On segments vi-xii there is a deep secon- 

 dary furrow anterior to the setae. On segments xi and xii there is 

 a slight tertiary furrow on the anterior and the posterior thirds of 

 the segment. On segment xiii there are two slight furrows anterior 

 to the setae. 



The first dorsal pore is in 11/12. Pores are also present in 12/13, 

 17/18, and posteriorly. 



The setae are eight per segment and begin on ii. Just poste- 

 rior to the clitellum ah is less than cd, cd is less than he, and aa is 

 larger than he, dd is greater than one-half of the circumference. More 

 posteriorly he and cd decrease in size and become nearly equal. 



The clitellum begins anterior to the setae of xiii and extends to 

 just behind the setae of xvii. Intersegmental furrows and dorsal 

 pores are lacking. 



The male pores are conspicuous transverse slits on xvii. The 

 center of each pore is in line with seta h. Two reddish setae pro- 

 ject from each pore.
