easily, except in sections in the intersegmental furrows 

 13/14, 15'1G on setii-Iine h. Male and ieniale apertures 

 cannot be identified. 



Culour. — In the live specimens the whole body is a pale 

 grey, or even slightly brownish in sonio, with the usual dark 

 dorsal and ventral bands. There is no colour-change in the 

 preserved material. 



Internal uryanisation. — The first recognisable septum is 

 4/5; septa 7/8-10/11 very thick, those of 11/12-14/15 

 fairly thick. Those of 4/5-6/7 are thicker than 16/17. 



The pharyngeal muscles are very strongly developed in 

 somites 6-7, though the ventral bands are few. The pharynx 

 is a spherical, strongly muscular chamber occupying somites 

 3-6. Pharyngeal wall in segment 7 thrown into pouches. 

 A well-developed spherical gizzard in segment 8. An 

 (jpsophageal pouch may be present in segment 9. The 

 intestine begins in segment 13, and in 14 the intestinal 

 wall is thick, white, and spherical, so as to simulate a 

 secondary posterior gizzard. There is a typhlosole, but no 

 pharyngeal glands. 



The dorsal vessel is a stout tube of uniform thickness 

 throughout. There is a typhlosolar vessel which comes to 

 the surface of the intestine at the level of segment 14, and 

 is continued forwards in the form of an independent vessel 

 entering the pharynx anteriorly. The last heart is in 

 segment 11. A lateral longitudinal vessel, about the thick- 

 ness of the dorsal vessel, extends from the anterior end 

 backwards in seta-line b. It is suddenly dellected inwards 

 at about the level of somite 13, or may be continued in the 

 same seta-line as far behind as segments 46-60, becoming 

 greatly attenuated in its course. There is only a sub- 

 intestinal vessel. 



The nephridia begin in segments 14-15. 



Male organs. — The testes and funnel in segment 10 not 

 identifiable, but made out in segment 11. There are four 

 pairs of seminal vesicles, irregular in shape and independent 

 of the loops of the heart. The anterior ones are attached 

 to the anterior face of septa 10/11 and 11/12. There are 

 no prostates. Male aperture in the intersegmental furrow 

 21/22 on seta-line h. 



A small ovary and an egg-sac are attached to the posterior 

 surface of the septum 12/13 dorsal in position. No oviduct. 

 Female orifice on segment 13 within aa. 



No spermatheca could be discovered in any of the three 

 specimens dissected. In one, however, a small whitish 

 pear-shaped organ occurred in seta-line /', segments 14, 15 on
