> Kobayashi's specimen (33/iii, 40/vi, 40/viii, 62/xii). 



The first dorsal pore is on 11/12 (3 specimens), 12/18 (14 speci- 

 mens), or 13/14 but with a definitely porelike marking on 12/lS 

 (3 specimens). 



The clitellum is annular, extending from 13/14r-16/17; interseg- 

 mental furrows and functional dorsal pores lacking though pore- 

 like markings are sometimes present; a few scattered setae present 

 ventrall}^ on some or all of segments xiv-xvi. 



The spermathecal pores are minute, widely separated, on tiny- 

 tubercles; four pairs, on v-viii, just anterior to the intersegmental 

 furrows, the latter clearly visible just behind the pores. 



Each minute male pore is located at the center of a circular,, 

 smooth, glistening disk, which is marked off b}' a slight but definite 

 circumferential furrow. A male pore disk may be at the general 

 epidermal level, slightly depressed in toto or folded and depressed at 

 the fold. In the latter case there is rather superficial resemblance 

 to the transversely slitlike opening of a copulatory chamber. The. 

 disks of Kobayashi's specimen are 3 intersetal intervals wide trans- 

 versely. 



The genital markings are circular to transversely oval or thickly 

 crescent-shaped. The latter are postsetal protuberances (often 

 smooth and glistening) on the posterior margins of v-viii, so placed 

 that the tiny spermathecal pore tubercle is within the concave pos- 

 terior margin of the crescent. Other genital markings are not so« 

 close to the intersegmental furrows; 1V2-4 intersetal intervals widfr 

 transversely, with a more or less easily recognizable, thick, cream- 

 colored rim and a grayish or brownish, translucent, central portion 

 that may be flat, concave, or convex. The markings are symmetri- 

 cally paired, presetal on viii, ix, xviii, and xix and postsetal on xviii. 

 On 10 specimens the markings are located as follows :
