Prostomium small, prolobous, under cover of segment i. 

 There were no dorsal pores. 



The setae, all of moderately large size, are closely paired ; ah=^ 

 cd=^aa; behind the genital region aa=bc, in front of the genital 

 region however aa>bc ; dd=^ of circumference. Setae a and b 

 are absent on segments ix and x, present on xi. 



A clitellum was doubtfully present, including segments ix, x, 

 xi ; in any case it was very indistinct. 



The male apertures are on small papillae^ in furrow xf* 

 between the setal lines b and c, and rather nearer to b ; the 

 papilla is bounded internally by the line b, while externally its 

 limit is within the line c. 



I cannot be absolutely certain, even after prolonged examin- 

 ation, of the situation of the female and spermathecal apertures ; 

 the female apertures appear to be just outside the line b, in furrow 

 rl, and the spermathecal apertures are apparently slit-like, the 

 centre of the slit just within the line c, in furrow s 



On segment ix, immediately in front of furrow to, a well- 

 marked transverse ridge extends across the mid- ventral line. The 

 ridge is slightly dumbbell-shaped, i.e. narrower in its centre; it 

 extends outwards on each side to a point slightly beyond the line 

 b. The grooves to and tt are less deep ventrally than in the other 

 parts of their circumference. The papillae of the male apertures 

 are surrounded each by a fairly definite circular depression, and 

 the surface of the body in the immediate neighbourhood of the 

 papillae is irregular, and to the outer side somewhat puckered. 



Septa 77 — 1, are thickened ; in front of this are a number of 

 septum-like sheets of muscle, convex forwards and attached 

 centrally to the pharynx^ of which they act as dilators and 

 retractors; but these are probably not homologous with septa. 

 The rest of the septa are thin. 



There are four gizzards, in segments xvi — xix, that in xvi 

 being smaller than the rest. There are no calcareous glands or 

 vascular bulgings of the oesophagus. 



The last heart is in segment ix. 



The nephridia are attached to the posterior face of each 

 septum, arching dorsalwards on each side to near the middle line 

 above the alimentary canal. 



The testicular sacs are suspended but not constricted by 

 septum To; the shape of each sac is pyriform, the pointed end, 

 directed forwards and outwards, being in segment ix, the rounded 

 end in x. The vas deferens originates in ix, is visible on both 

 sides of the septum, is long and coiled; it ends by piercing the 

 body-wall anterior and internal to the prostate. 



The prostate is a comparatively small whitish hemispherical 

 cushion-like mass on the ventral body-wall of x. 



The ovaries are free, not enclosed in an ovarian chamber, 

 conspicuous, attached beneath the arch of the nephridia to the 

 posterior face of septum tt. Funnels were not seen, The egg-sacs
