DESCRIPTIONS OF GENERA AND SPECIES 



495 



incomplete. Clitelhm, XIII~X7II, saddle-shaped. Setae of outer couples further apart 

 than inner. Male pores in line with seta 3. Oviducal pores in front of, and ventrad of, 

 inner seta. Genital papillae, one in front and one hehvtid, and rather dorsal of, each male 

 pore ; intersegmental in position. Dorsal pores commence XVIII/XIX. Gizzard in F; no 

 distinct calciferous glands; intestine begins in XVI. Testes and funnels, one pair only; 

 sperm-sacs in XII. Spermathecae in Fill, IX, each with two {or three) caeca. Last hearts 

 in XII. Penial setae present. Hah. — Grafton, Clarence River, N. S. Whales. 



(21) Megascolides ornatus (Eisen). 



Argilophilus marmoratus ornatus, EiSEN, Zoe, iv, p. 353. 



Definition. Length, about 150 mm. Clitellum, XIII-XFIII. Genital papillae paired on 

 FIII/X, XF/XFII, XIX/XX, intersegmental; ventral setae closer together than lateral. No 

 calciferous glands. Last hearts in XIF. Spermathecae in Fill, IX. Sperm-sacs in 

 X-XII. Nephridia without terminal vesicle, alternate in position. Penial setae ornamented 

 with spines. Had. — San Francisco to Oregon. 



This and the following species (regarded by Eisen as subspecies or varieties) were 

 placed by him in a distinct genus, Argilo'philus. There does not, however, appear 

 to me to be any good grounds for placing them in a genus apart from Megascolides. 

 Their anatomy is described in the most detailed fashion in a subsequent memoir 

 (16). 



(32) Megascolides papillifer (Eisen). 



Argilophilus marmoratus papillifer, Eisen, loc. cit., p. 353. 



Definition. Like the last species, but genital papillae median, intersegmental, one to seven in 

 number. Hah. — San Francisco and southwards. 



(33) Megascolides australis, MoCoy. 



M. australis, McCoy, Prodr. Zool. Vict. Dec. i, 1878. 



Ifotoscolex gippslandicus, Fletcher, Proc. Linn. Soc. N. S. W.,ii (a), 1888, p. 603. 



Definition. Length, 1*33 m.; diameter, ij mm. ; number of segments, 500. Prostomium 

 incomplete, Clitellum, XIII-XXI. Setae of outer pair further apart than of inner. 

 Male pores occupy position of ventral pair of setae which are absent. Papillae median 

 on XFII/XFIII, XFIII/XIX, and XIX/XX; the middle papilla carries the male pores, and 

 is more extensive than the others. Dorsal pores commence XF/XFI. Gizzard in F; 

 intestine begins in XIX, Septa IF/XIF thickened. Last hearts in XIII. Nephridia
