NO. 3 NEW EARTHWORMS FROM CHINA GATES I3 



PHERETIMA PAETA, n. sp. 



Length 75-136 mm, diameter 5-6 mm. Setae : viii/22-24, xvii/18-21, 

 xviii/io-i6, xix/21-24, xx/65-68. First dorsal pore in 11/12-12/13. 

 Spermathecal pores on circular to oval areas within deep invagina- 

 tions with transversely slitlike apertures, two pairs, in 7/8-8/9. Male 

 pores on the dorsal wall of large copulatory chambers conspicuously 

 protuberant into the coelom. On the median wall of the copulatory 

 chamber a presetal, transversely oval genital marking, occasionally 

 also a postsetal marking ; on the roof of the chamber one or two further 

 markings of variable shape and size. External genital markings paired, 

 on the posteriormost margins of vii and viii, each marking one to 

 three intersetal intervals median to the aperture of the spermathecal 

 invagination. 



Intestinal caeca compound, dorsalmost secondary caecum the longest. 

 Testis sacs of x and xi unpaired and ventral. Spermathecal diver- 

 ticulum with a muscular stalk and an elongately tubular seminal cham- 

 ber, the latter looped back and forth in a regularly zigzag fashion. 



Type. — U.S.N.M. no. 20103, from Song Pan, Szcchuan. 



Distinguished from P. omeimontis by the copulatory chambers, and 

 from P. scliiiiardae by the larger size, the invagination of the sper- 

 mathecal pores, and the presence of genital markings. 



PHERETIMA PAPILLIFERA, n. sp. 



Length 100 mm, diameter 4 mm. Setae: vi/ii(-|- ?), vii/i3( -|- ?), 

 xvii/i8(-|- ?), xviii/io, xix/io, xx/ca. 41 ; lacking on ii-iii and dor- 

 sally on iv. First dorsal pore in 11/12. Spermathecal pores minute and 

 superficial, three pairs, in 5/6-7/8. Male pores superficial, at centers 

 of circular areas demarcated by slight furrows. Genital markings 

 paired, presetal, on xi-xiv. 



Intestinal caeca simple. Testis sacs of x and xi paired. Spermathe- 

 cal diverticulum with a short muscular stalk and a longer, more irregu- 

 lar seminal chamber. Genital marking glands sessile on the parietes. 



Type. — U.S.N.M. no. 20104, from near Zachoo, Szechuan. 



Distinguished from sexthecal Chinese species of Pheretinm with 

 spermathecal pores in 5/6-7/8 by the absence of setae on ii-iii and 

 dorsally on iv and by the location of the genital markings. 



PHERETIMA PECTENIFERA Michaelsen, 1931 



The male pore region of P. pectenifera is so remarkably similar to 

 that figured for P. yamadai Hatai, 1930, that the former may be, in 

 reality, a synonym of the latter. Hatai 's species is not adequately
