Remarhs. — Some of the preclitellar, ventral setae are enlarged 

 and modified; 0.7-1.0 mm in length, the ectal tip ornamented with 

 circles of very fine teeth. 



In spite of their size the worms just described are not siiflBciently 

 mature to enable specific identification. The crescentic furrow and 

 lateral lip at tlie margin of the male pore area probably represent 

 an early stage in the formation of the type of male parietal invagina- 

 tion that characterizes P. praepinguis. 



No preclitellar genital markings were observed in the first exami- 

 nation, but after completion of the study of the holotype of P. 

 praepinguis the worms were reexamined and a tiny area of peculiar 

 appearance was noted just anterior to each spermathecal pore. This 

 area may possibly represent the rudiment of the genital marking on 

 the anterior face of the spermathecal invagination of praepinguis. 



One of the prostatic ducts of the type of praepinguis was pur- 

 posely broken off by a quick jerk, thereby revealing a "joint" some- 

 what similar to that described above except that both ball-and- 

 socket portions are more flattened out. 



Numbers of parasites (nematodes and Protozoa) were found in the 

 coelomic cavities of the two acliteUate specimens that were opened.

Material examiiied. — From the U. S. National Museum: 1 clitel- 

 late specimen labeled '"''Pheretima szechuanensis Chen, paratype, Y 

 Chen." 



Remarks. — On each male pore area of xviii are tiny rudiments of 

 three markings, two of which are toward the median margin with one 

 presetal and one postsetal, while the third is toward the lateral margin 

 and probably represents the rudiment of a male pore disk. Just 

 lateral to the male pore area is a rudiment of a lateral lip such as is 

 associated with the type of parietal invagination found in P. tschi- 

 liensis and related forms. 



The intestinal caeca are simple, long, and slender, with slight 

 incisions of the ventral margin. 



The spermathecae are rudimentary. 



The worm is quite obviously not P. szechuanensis.

According to Gee, Boring, and Wu (1927), "the common Soochow 

 worm," which they identified as ''^Perichaeta hupehensis,^^ has two, 

 three, or four pairs of spermathecal pores though the "normal num- 

 ber is three" on 6/7-8/9 (p. 1). The large apertures on xviii, which
