The abnormalities of this worm may have been brought about as 

 the result of the presence of large numbers of parasites. In the 

 postclitellar portion of the worm there are many gregarinoid cysts 

 on the body wall, fairly regularly distributed throughout the whole 

 of this portion of the worm. There are also a few cysts on the 

 dorsal face of the gut. In addition, there are nematodes in the coelo- 

 mic cavities, throughout the entire length of the worm. 



Fang (1983, p. 179) refers three worms "apparently without clitel- 

 lum" from Nan-hu to F. vulgaris. One of these specimens, labeled 

 "T^. vulgaris Chen. Ichang, Hupeh, 1929" has been available for 

 examination. The specimen is quite obviously aclitellate. The worm 

 is characterized b}' large, club-shaped, copulatory chambers, a 

 U-shaped testis sac belonging to x and spermathecal invaginations 

 into the coelomic cavities as in P. vulgaris. Other sex organs are 

 more or less rudimentary. 



Fang also states that "some individuals collected from Peiping by 

 Mr. C. J. Shen are referable to this species," i. e., P. vulgaris. 

 Chen's species, however, comprised two distinct forms. Fang does 

 not indicate which of these forms is involved, and accordingly the 

 record from Peiping cannot be accepted. 



PHERETIMA species, 1 



Material examined. — From Dr. Graham: 2 aclitellate specimens 

 labeled "Mt. Omei, 6,000 feet, August 1922"; 2 aclitellate specimens 

 labeled "Shin Kao Si, Mt. Omei, 4,400 feet, August 25-26, 1924." 



External characteristics. — Length, 242-357 mm. Diameter, 11-13 

 mm. 



The setae begin on ii, on which segment there is a complete circle. 

 There is no definite midventral gap in the setal circles ; the middorsal 

 gaps are of variable width. Setal numbers are as follows : 



The first dorsal pore is on 11/12 (1 specimen) or 12/13 (3 speci- 

 mens). 



There is no indication of the development of clitellar glandularity 

 on any of the specimens. A single female pore can be recognized on 

 xiv on one specimen. 



The spermathecal pores are minute, on tiny tubercles or areas of 

 especial smootlmess ; three pairs on 6/7-8/9.
