The spermathecal pores are minute, widely separated, on tiny 

 protuberances ; two pairs, on 7/8-8/9. 



At the center of each male pore area on xviii of specimens A is 

 a narrow transverse ridge, roughened or finely lobulated. On the 

 lateralmost portion of this ridge is a tiny papilla on which is the 

 minute male pore. No setae are visible on the ridge, which is in 

 line with the setal circle. Just anterior and just posterior to each of 

 these male pore ridges are two transverse rows of tiny, very short, 

 columnar tubercles or papillae; the ventral face of each column is 

 flattish or slightly depressed, the central area grayish, translucent, 

 and surrounded by a narrow, opaque, whitish rim. The number of 

 the papillae in each male pore region varies from 15 to 17. The 

 body wall immediately in front of and just behind the male pore 

 ridge together with the tubercles thereon is slightly depressed. The 

 whole of the region just described is surrounded by i-6 concentric 

 furrows ; each furrow outlines a transversely oval area with the more 

 pointed portion mesially. The furrows reach beyond the limits of 

 xviii, slightly invading segments xvii and xix. 



On specimen B the male pore ridges are not clearly visible; 

 there are only 10-13 markings, none of which have a columnar 

 appearance ; the concentric furrows outline longitudinally oval areas. 



On specimen C the male pore ridges are also not clearly visible, 

 but the concentric furrows are like those on specimens A. The geni- 

 tal markings are closely crowded and, as a result of maceration, are 

 difficult to count; about 17 markings on each area. 



On Kellogg's specimens, the number of markings on a male area 

 varies from 10 to 23, the transverse ridges visible. The male pore 

 tubercles are shghtly lateral to, and usually a trifle larger than, the 

 genital markings. 



The preclitellar genital markings (A) are very similar to those 

 of the male pore region but do not have a columnar appearance 

 and are located slightly median to the spermathecal pores, in trans- 

 verse rows of 2-5, one row each on the anteriormost margins of viii 

 and ix and the posteriormost margins of vii and viii. The genital 

 markings may be entirely lacking in the vicinity of a particular sper- 

 mathecal pore. On specimen B the preclitellar genital markings are 

 (probably) almost entirely lacking. There is, however, a single very 

 definitely outlined marking on the posteriormost margin of vii on the 

 right side just median to the spermathecal pore of 7/8. On specimen 

 C the genital markings are quite characteristic, each row with 5-7 

 markings. On Kellogg's specimens the number of markings in a 

 row varies from to 8.
