4o6 Records of the Indian Museum. [Vol. VIII, 



The prostates are tubular, much coiled, in segments xvii-xx ; 

 they become more shining and muscular towards their outer end. 



The sac of the penial setae, in length about 2 mm., of loose 

 texture and not very definite shape, projects inwards on each side 

 between prostate and intestine; its outer termination is situated 

 mesially to the end of the prostatic duct. 



Ovaries and ovarian funnels are situated in xiii. 



The spermathecae are compact, firm, subspherical in shape, 

 with short thick duct. On the posterior aspect, at the junction of 

 ampulla and duct, is a series of six small iridescent diverticular 

 chambers ; the individual chambers being fused on each side with 

 their neighbours form together a semi-circular rosette. 



The penial setae (fig. 21) are several in each bundle, about 

 three fully formed and three immature. Their length is 3'5 mm., 

 diameter 31 ik The shaft is gently curved, with a sharply marked 

 hook at its free extremity ; the shaft itself is slightly swollen 

 just proximal to the hook, the hook itself is narrower. The distal 

 portion of the shaft is ornamented with numeious rows of minute 

 dots, which may extend across the visible surface of the shaft, or 

 may be shorter, and convex distalwards. In an older seta the 

 hook was not so sharp nor so narrow ; in one of two setae that had 

 not yet escaped from their sheath, the hook was small, but well 

 marked, in the other very faintly marked. 



Eutyphoeus aborianus, sp. nov. 

 iTl. xxvii, fig. 22.) 



A single specimen, in a rather poor state of preservation, in a tube with 

 E. koboensis. Kobo, Abor country, alt, 400 ft. , in earth, 2-xii-i9ii. 



Length 9 inches, diameter, max. 6 mm. Colour pale, with 

 greyish patches mainly on dorsal surface. 



Prostomium mmute, just visible, withdrawn under cover of 

 the first segment. Segments i-iii consist of single annuli, iv-v of 

 two, vi of three with slight indications of two others, vii-viii of 

 five, ix of five principal annuli, each divided, giving ten in all; 

 x-xii have five annuli, and behind the clitellum the segments are 

 triannulate, but of the three annuli the first and last may be more 

 or less distinctly sub-divided, giving four or five in all. All annu- 

 lation and segmentation was lost over the middle region of the 

 body owing to the state of preservation. 



The first dorsal pore was at the posterior border of the clitel- 

 lum, i e. in groove H. 



The setae are small, and paired, — rather widely in the case of 

 the lateral couples. In front of the clitellum aa ^= i\ab; be 

 slightly > aa, = ilab; cd about = aa. Behind the clitellum aa 

 = 2a&, or further back = 3^6; &c = ilab; cd = ihab. No setae 

 were discoverable on segments ii, iii and iv. 



The clitellum includes f xiii-xvii = 4I ; setae are present, but 

 there is no external annulation.
