4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 93 



D. jiipoiiica Chen, 1933, is prol)ably only in part, if at all, con- 

 specific with D. japomca. Chen's forms are characterized by greater 

 size (70 to 200 by 3 to 5^ mm rather than 28 to 65 by i to 3 mm), 

 location of the male pores, at least in part, on penes or penislike pro- 

 tuberances, and the absence of the characteristic appendices on the 

 ovisacs. Possibly Chen's material is to be referred to two distinct 

 species — mention is made of " some smaller ones about 30 mm long 

 and 2 mm wide also showing sexually mature ". 



DRAWIDA LINHAIENSIS Chen, 1933 



The types of this species are proljably not fully mature — vide 

 smooth or finely-granular surface of the prostates, the small size of 

 the spermathecal ampullae, and the lack of clitellar development 

 (" clitellum traceable only in one specimen "). The male porophore 

 may possibly contain a spheroidal gland as in D. ncpalcnsis. 



Further information is needed on the penis { ?) pouch ( ?) and rela- 

 tion of the prostate thereto, as well as on characteristics of the sper- 

 mathecal atria and ovarian chamber in fully sexual specimens. 



DRAWIDA SINICA Chen, 1933 



Apparently a good species — the prostates and the spermathecal atria 

 certainly appear to be quite characteristic. The types are not, how- 

 ever, fully mature — vide absence of ova in the ovisacs and ovarian 

 segment and the small size and emptiness of the spermathecal 

 ampullae. 



DRAWIDA SYRINGA Chen, 1933 



The description is rather abbreviated and the species cannot be ade- 

 quately characterized in absence of information with regard to the 

 central body of the prostates and the relation of the prostatic duct to 

 the penis pouch ( ?). Length of ovisacs, in view of rather wide intra- 

 specific variation in this characteristic, may possibly be of little 

 importance. 



PHERETIMA Kinberg 



In this genus especial attention is necessary, in identifications and 

 si^ecific descriptions, to the characteristics and contents of the invagi- 

 nations at the ectal ends of the male deferent apparatus and of the 

 spermathecae, to the intestinal caeca, to the testis sacs and their relation 

 to the seminal vesicles and to the glands of the genital markings. 

 The failure to describe adec[uately some of these characteristics has
