NO. 3 NEW EARTHWORMS FROM CHINA GATES 3 



D. gisti var. anchingiayta Chen, 1933, is not adequately described 

 but differs from the types as follows : limitation of the penis 

 pouches ( ?) to the body wall, small size and smooth surface of the 

 prostates, and the presence of the spermathecal atria in vii rather than 

 viii. These differences are important enough to distinguish the worms 

 specifically from D. gisti. The specimens may not be sexually ma- 

 ture — znde absence of granulations on the prostates, the empty ovisacs, 

 and the small size of the spermathecal ampullae, as well as the indis- 

 tinctness of the clitellum. 



DRAWIDA GRAHAMI, n. sp. 



Length 55 mm, diameter 4 mm. Spermathecal pores in 7/8 midway 

 between b and c. Male pores in be, nearer to b than to c, on small 

 porophores seated on lo/ii, intersegmental furrow lo/ii ending 

 blindly against the lateral and median sides of the porophores. Genital 

 markings on vii-xiii, each marking with a firm, rounded gland pro- 

 jecting through the parietes into the coelom. 



Vas deferens short. Prostates sessile on the parietes, outline circu- 

 lar ; central body tiny, ovoidal, pointed end buried in the parietes. 

 Segment xi reduced to a horseshoe-shaped ovarian chamber. Sper- 

 mathecal atria finger-shaped, erect in viii. 



Type. — U.S.N.M. no. 20093, from Suifu, Szechuan. 



Distinguished from D. japonica by the absence of the appendix 

 on the ovisacs, the more median location of the spermathecal pores, 

 and the sessile prostates. 



DRAWIDA JAPONICA Micliaelsen, 1892 



This species is characterized by a posterior continuation of the 

 ovisac into a very long and slender rodlike appendix, which may 

 extend as far back as segment xliii. These appendices were over- 

 looked by both Michaelsen and Stephenson. 



The central body of the prostate is shortly tubular, finger-shaped. 

 The vas deferens passes ectally into the body wall just median to 

 the prostate. The ovarian chamber is horseshoe-shaped. The male 

 pores are located on segment x on the ventral faces of porophores in 

 he, nearer to b than to e. 



D. japonica f. siemsseni Michaelsen, 1910 and 193 1, is probably 

 specifically distinct from D. japonica. It differs from the latter in 

 size, number of gizzards, external genital markings and characteris- 

 tics of the male porophores. Unfortunately, the internal organs of 

 the single specimen have been lost so that the s]3€cies cannot be ade- 

 quately characterized.
