at first sight this appears not to be the case ; but the large dark 

 vessel running superficial to the sac is not the proper heart). 



The prostatic duct is looped or coiled ; it is thin at first, but 

 becomes stout towards its ectal end. 



I found no ovisacs. 



The spermathecae differ from those of Michaelsen's specimens 

 (fig. 1). The ampulla is ovoid ; the duct, 

 nearly as long as the ampulla, is narrow 

 at first, then swells and becomes shining 

 and firm. The diverticulum is as long 

 as the ampulla and duct together ; it 

 arises from the ectal end of the duct, and 

 is narrow and tubular ; its inner (ental) 

 portion consists of a number of short 

 closely adpressed loops and has a crenulat- 

 ed appearance; the ectal portion becomes fig. i.—Pheretima site- 

 smooth and shining towards its termina- toria ; spermatheca.

External Characters: — A long specimen measures 167 mm., 

 but sexual specimens are found down to 85 mm. Diameter, max. 

 4 mm. Segments 174. Colour deep purple dorsally ; lighter, 

 of a violet tint, ventrally. The body is somewhat flattened dorso- 

 ventrally. 



Prostomium epilobous \ ; tongue not closed behind. 



Dorsal pores begin from furrow 4/5. 



The setae are in rings, and are more closely set ventrally. 

 The dorsal break is either absent or very small (zz=ca. i\ yz) ; the 

 ventral break is absent or very small behind the genital region, 

 and small (ca. ij ab) in front of the genital region. The following 

 numbers were counted : v/ ca. 38, ix/41, xii/40, xix/42, and 42 in 

 the middle of the body. 



There was no clitellum to be seen in any of the specimens. 



The male pores are on segm. xviii, the anterior and posterior 

 borders of which are bowed forwards and backwards respectively. 

 The segment presents a transverse groove, usually shallow but 

 occasionally deep. The pores are short longitudinally placed 

 slits at the ends of the groove ; they are not far from the midven- 

 tral line, in line with about the fourth seta on each side. 



The female pores were not visible.
