Figure 14. Female reproductive systems of. paratypes of Dalhousia species. A,C. D. globosa. A, oviduct viewed from 
left side; C, detail of sperm sac and associated oviduct. B,D. D. harrisi, B, oviduct viewed from left side; D: 
detail of sperm sac and associated oviduct. ag — albumen gland, cd – common duct, cg - capsule gland, со“ 
coiled oviduct, po — pallial opening of oviduct, ppc — posterior pallial wall, sp — sperm stored in oviduct, sp$ 
— sperm sac, vc — ventral channel. Scales (A,B) 0.5mm. 
roof), bean-shaped, oval to narrowly-oval in section. Pallial vas deferens emerges ventrally from 
posterior end of pallial portion of prostate gland, straight until near penis where it weakly undulates- 
Penis (Fig. 12D) unpigmented, distal part short, narrow, tapering, tapers gradually into long, narrow: 
slightly tapering base. Penial duct strongly undulating in base, straight in distal section. Penis 
located just to right of midline, 0.19-0.25 mm behind right eye. 
Ovary of 0.6-0.9 whorls. Coiled oviduct (Fig. 20A,B, co) with double loop, anterior U-shape bent 
anteriorly and posterior loop, details variable (c.f. Fig. 20A and B); distal part with weak elbow jus! 
before opening ventrally to bursal duct well behind posterior pallial wall (Fig. 20C). Common duct 
(Fig. 20C, cd) straight to pallial wall. Seminal receptacle (Fig 20C, sr) ovoid, 0.08-0.12 mm 10 
length, 0.01—0.08 mm in width, at anterior edge of bursa; duct short. Bursa copulatrix (Fig. 20A-C: 
bc) ovoid to elongate-ovoid, (0.14-)0.29 mm in maximum length and width; bursal duct simple: 
0.06-0.08 mm long, emerging from antero-ventral face (more nearly mid anterior in one specimen): 
Albumen gland (Fig. 20A,B, ag) 0.19-0.31 mm in length, 1/6-1/4 of length in pallial roof; length 
relative to capsule gland variable (0.5 to 1.12) (c.f. Figs 20A and B). Capsule gland (Fig. 20A,B, cg) 
truncated anteriorly, 0.26-0.37 mm in length, oval to narrowly oval in section. Ventral channel (Fig: 
20A,B, vc) broad, lacking distinct vestibule, short, slit-like opening (Fig. 20A,B, po) beneath anterior 
end of capsule gland. 
Distribution (Fig. 15). Springs known to contain this species are listed in Table 9 (Appendix 3). 
This species lives in a few small (mainly cold) seeps, and in the shallow, lower outflow of at leas!
