developed on the ventral surface, and connecting the three 
tubercles on a segment constitute a characteristic feature. 
Each 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 12-24, there is a clitellar ridge, dorsal to the tubercles 
and becoming continuous with the broader wing from 
segments 25-32, 36, and occasionally repeated on one or 
both sides on segments 40-45. The border is greatly 
foliated. No genital pores can be made out except in 
sections. 
Colour.—In the liying 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 
yellow. Dark dorsal and ventral bands occur. The yellow 
posterior part of the body becomes rather dirty. The mid- 
clitellar region is deeply red, while the tubercles and the 
wing are white. In the spirit-specimens the yellow and 
even the red may be preserved in varying degrees. 
Internal organisation. — Septum 6/7 moderately and 
7/8-10/11 very thick. Septum 4/5 is the first recog- 
nizable one. 
The pharynx extends up to segment 64 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 coelomic 
chambers. 
Male organs.—There are four pairs of seminal vesicles in 
segments 9-12, those in 9, 10, and 12 being conspicuous, 
‘They 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. The vesicles are irregularly spherical 
bodies, soft and lobulated. No prostates. 
Testes and funnels in segments 10-11 both conspicuous 
and easily made out. Male aperture in intersegmental 
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. 
Spermathecz are situated in segments 13-16, They are
