PHERETIMA ASPERGILLUM (E. Perrier), 1872 



In the synonymy of this species there must now be placed the fol- 

 lowing: Pheretinia laiita Ude, 1905, Pheretima para glandularis Fang, 

 1929, Pheretima siemsseni Michaelsen, 1931 (in part). 



PHERETIMA BUCCULENTA, n. sp. 



Length 135 mm, diameter 6 mm. Setae: vi/22, vii/22, viii/25, 

 xvii/i6, xviii/20, xix/20. First dorsal pore in 12/13. Spermathecal 

 pores minute and superficial, four pairs, in 5/6-8/9. Male pores on 

 tiny, conical tubercles in the dorsalmost portions of deep parietal 

 invaginations with longitudinally slitlike apertures. Genital markings 

 paired, presetal on xviii. 



Intestinal caeca simple. Testis sacs of x and xi unpaired and 

 ventral. Genital marking glands sessile but protuberant through the 

 parietes into the coelom. 



Type. — U.S.N.M. no. 20096, from "Szechuan ". 



Distinguished from other octothecal Chinese species of Pheretima 

 by the combination of superficial spermathecal pores and deeply invagi- 

 nate male pores. 



PHERETIMA EXILIS, n. sp. 



Length 68 to 85 mm, diameter 2 to 2| mm. Setae: vi/39, xvi/6, 

 xvii/io-15, xviii/8, xix/ii-13, xx/50. First dorsal pore in 12/13. 

 Spermathecal pores minute and superficial, two pairs, in 5/6-6/7 or 

 on the posteriormost margins of v and vi. Male pores within slight 

 depressions on glistening, not sharply demarcated areas. Genital mark- 

 ings paired on xvii and xix, probably postsetal. 



Intestinal caeca simple. One pair of testis sacs in x. One pair of 

 vertical testis sacs in xi. Seminal vesicles of xi included within the 

 posterior testis sacs. Genital marking glands sessile but slightly pro- 

 tuberant through the parietes into the coelom. 



Type. — U.S.N.M. no. 20097, from Suifu, Szechuan. 



Distinguished from quadrithecal Chinese species of Pheretima with 

 spermathecal pores in 5/6-6/7 by the inclusion of the seminal vesicles 

 of xi within the posterior testis sacs. 



PHERETIMA FLEXILIS, n. sp. 



Length 40 mm, diameter 2 mm. Setae; vii/i6, viii/i6, xvii/io, 

 xviii/io, xix/ii. First dorsal pore in 13/14. Spermathecal pores 

 minute and superficial, three pairs, in 6/7-8/9. Male pores superficial, 

 at the centers of tiny, transversely oval areas, each area surrounded by
