An ental portion of the spermathecal diverticulum is usually elon- 

 gate-ovoidal and definitely marked off from the remainder of the 

 diverticulum. An ental portion of the slenderer part of the di- 

 verticulum, is, like the ovoidal part, filled with sperm and often 

 looped into a regular zigzag, the limbs of the loops short and in 

 apposition. The stalk portion of the diverticulum is not marked off 

 externally from the looped portion of the seminal chamber. 



Associated with each preclitellar or postclitellar genital marking 

 is an ovoidal glandular mass. This mass may project slightly into 

 the coelomic cavity or may be bound down to the parietes or be 

 located within the parietes between longitudinal muscle fibers. The 

 stalks, which are narrower than the glands, may or may not be 

 visible within the coelomic cavity. The stalked preclitellar glands 

 are readily recognizable in the coelomic cavity of specimen C. Only 

 one stalked preclitellar gland is visible in the coelomic cavity of 

 specimen B. 



Remarks. — Lin's specimens were from Amoy and were identified 

 by Michaelsen. According to Lin the number of setae on segments 

 xx-xxi varies from 86 to 93. 



P. paraglandulans is so very similar to P. aspergilluni with regard 

 to a number of structures of major systematic importance that there 

 can be little if any doubt that the two are synonymous (types have 

 not been available for study). However, in P. paraglandularL?, ac- 

 cording to Fang, the male pores are large slits ; there are "moderate'" 

 copulatory chambers, each containing an elongate genital papilla; 

 septum 8/9 is thickened, only 9/10 is lacking ; the gizzard is between 

 septa 8/9 and 10/11 and accordingly belongs morphologically either 

 to ix or x; the intestinal caeca orginate in xxv and extend only 

 through one segment, there are two pairs of testis sacs, the conjoined 

 transverse pairs comiected with each other anteroposteriorly. All 

 these rather unusual characteristics are doubtless the result of errors 

 in observation or interpretation. It is scarcely necessary to discuss 

 all these errors. The gizzard is always in segment viii in the genus 

 Pheretima. Fang has mistaken septa 5/6-7/8 for septa 6/7-8/9. 

 The elongate genital papilla is doubtless the transverse ridge on the 

 male area. 



Fang's figure of a male genital area would do quite well for that 

 of one of the Hamburg specimens if the transverse ridge were lobu- 

 lated instead of smooth and with genital markings. An intestinal 

 caecum of one of the Hamburg specimens is very much like the 

 figure of the caecum in Fang's paper. 



Chen examined Fang's specimens but failed to correct the errors 

 in Fang's account. According to Chen the hearts of x are lacking;
