developed on the ventral surface, and connectinfj the three 

 tul)crcles on a segment constitnte a eiiaracteristic feature. 

 Ea(;li tubercle occupies the whole width of the segment, and 

 consequently touches one another so as to form a continuous 

 structure. In the case of the lateral tubercles from seg- 

 ments 12-2'1, there is a clitellar ridge, dorsal to the tubercles 

 and becoming continuous -svith the broader wing from 

 segments 25-32, 3G, and occasionally repeated on one or 

 both sides on segments 40—15. The border is greatly 

 foliated. No genital pores can be made out exce])t in 

 sections. 



Colour. — In tlie Hying condition this is a beautiful worm, 

 covered by more than one vivid colour. The anterior part 

 of the body down to segment 18 is bright orange, and 

 from behind down to about segment 40 it is a warm 

 jellow. Dark dorsal and ventral bauds occur. The yellow 

 })osterior part of the body becomes rather dirty. The mid- 

 clitellar region is deeply red, while the tubercles and the 

 '\^ing are white. In the spirit-specimens the yellow and 

 even the red may be jjrcserved in varying degrees. 



iHternal organisation. — Septum Qj7 moderately and 

 7/8-10/11 very thick. Septum 4/5 is the first recog- 

 nizable one. 



The pharynx extends up to segment 6i and is thrown into 

 pouch-like sacs in segment 7 . Gizzard spherical, very large 

 in segment 8. Intestine begins in segment 14. A typhlo- 

 sole is present. Pharyngeal glands present, having the 

 same relation and structure as those of the previous species. 



Dorsal vessel single. Last heart in segment 11 and an 

 additional one frequently in segment 12. 



Meganephridia commencing from segment 12. None in 

 front. They are enclosed in the ventral secondary ecclomic 

 chambers. 



Male organs. — There are four pairs of seminal vesicles in 

 segments 9-12, those in 9, 10, and 12 being conspicuous. 

 I'hey are directly attached in the usual way to the anterior 

 and posterior surfaces on septa 9/10, 10/11, 10/11, and 

 11/12 respectively. Tiie vesicles arc irregularly spherical 

 bodies, soft and lobulated. No prostates. 



Testes and funnels in segments 10-11 both conspicuous 

 and easily made out. Male aperture in interscguiental 

 furrow 27/28 on seta-line b. 



Ovisacs and ovaries situated in segment 13 on the dorsal 

 vessel, each is a large flat body, loosely attached to the 

 posterior surface of septum 12/13. Oviducts not identifiable. 

 Female orifice segment 13 within aa. 



Spermathecse are situated in segments 13-lG. They are
