straight except for a very short, slender, ental portion that is not 

 glistening and which is bent into a tiny quirk. 



The spermathecal duct is very short, about one-fourth (or less) 

 the length of the ampulla, narrowed in the parietes to a tiny conical 

 point. The diverticulum comprises a short slender stalk and a much 

 longer, slightly wider, thin-walled seminal chamber. The latter is 

 variously bent, twisted, or looped. 



The genital marking glands are smooth and ovoidal ; the coelomic 

 portion of the stalks fairly long and glistening. 



Remarks. — The body wall is so transparent in places that exact 

 enumeration of the setae is difficult. 



P. -116X1118 is distinguished from P. hupeiensis (Michaelsen, 1895) 

 by the absence of septa 8/9-9/10 and from P. leucocirca Chen, 1933, 

 by the characteristics of the testis sacs and the included seminal 

 vesicles and hearts.

1935. Pheretima fornicata Gates, Smithsonian Misc. Coll., vol. 93, no. 3, p. 9 



(type locality: Tatsieulu, Szechwan ; types in the U. S. Natioiial 

 Museum).

Mater^ial examined. — From Dr. Graham: 3 clitel'ate specimens 

 labeled "Tatsienlu, 12,000 feet, July 7-9, 1923" ; 1 clitellate specimen 

 in poor condition labeled "Between Gin Keo Ho and Dawei, 1,300- 

 5,000 feet, August 1-2." 



External characteristics. — Length, 78-90 mm (100 mm, Dawei 

 specimen ) . Diameter, 4r-6 mm. 



The setae begin on ii, on which segment there is a Avide dorsal gap 

 in the setal circle. There is a small but fairly regular, midventral 

 break in the setal circles ; the middorsal gap usually larger but varia- 

 ble in width. The setal numbers are as follows : 



' In addition setal pits in which no setae were definitely recognized. 



The first functional dorsal pore is on 12/13 on each specimen, but 

 there is a porelike marking on 11/12.
