NEW EARTHWORMS FROM CHINA GATES

PHERETIMA HUPEIENSIS (Michaelsen), 1895 



The testis sacs of x and xi are U-shaped. Chen (1933) appears to 

 regard the testis sacs as annular, Chen's account is not quite clear. 

 He places the seminal vesicles of xii in a membranous sac similar to 

 that which contains the seminal vesicles of xi, though there is no testis 

 sac in xii. Coelomic coagulum may sometimes be compacted around 

 the seminal vesicles so closely as to produce an appearance somewhat 

 similar to that of a testis sac filled with testicular coagulum. 



Perichaeta Jmpeiensis Gee, Boring, and Wu, 1927, is certainly not 

 P. hit peiensis and is probably a composite of three distinct species. 



PHERETIMA IGNOBILIS, n. sp. 



Length 55 mm, diameter 3 mm. Setae: vi/17, vii/i6, viii/i6, 

 xvii/15, xviii/9, xix/i6. First dorsal pore in 11/12. Spermathecal 

 pores in parietal invaginations with transversely slitlike apertures, 

 four pairs, in 5/6-8/9. Male pores on the roof and toward the median 

 side of transversely slitlike depressions. No genital markings. 



Intestinal caeca simple. Testis sacs of x and xi paired and ventral. 



Type. — U.S.N.M. no. 20101, from near Ningyuenfu, Szechuan. 



Distinguished from all octothecal Chinese species of Pheretima by 

 the location of the spermathecal pores in parietal (or deeper?) 

 invaginations. 



PHERETIMA LIMELLA, n. sp. 



Length 60-85 ^^> diameter 2^-5 mm. Setae: v/38, vi/51, xiv- 

 xvi/-f , xvii/18-29, xviii/14-21, xix/18-26. First dorsal pore in 12/13. 

 Spermathecal pores minute and superficial, one pair, in 5/6. Male

lactophenol. 



pores at centers of small, oval tubercles; a thin fold of tissue at the 

 lateral margin of each male porophore can be drawn mesially over the 

 tubercle in the manner of an eyelid. Genital markings paired and 

 presetal on xvii.
