Fig. 14 & 15. Ventral and dorsal view respectively of another specimen in 
cedar-wood oil. 
Fig. 16. The type-specimen in oil, with the dorsal side upwards. It is to be 
observed that the large, unbranched, sinuous uteri reach more 
frontalwards than the very long and remarkably narrow pharyngeal 
chamber. 
Enterogonia pigrans Haswell var. novæ-zealandiæ n. var.

Fig. 17. A specimen in ventral aspect to demonstrate the location of the 
mouth a small part, mp, of the pharynx protrudes through it) and 
the sexual openings 
Cryptophallus sondaicus n. sp. 
Figs. 18—21. 
Fig. 18. Dorsal aspect of the animal in alcohol. As the insignificant tenta- 
cular rudiments lack giands in the epidermis, they contrast as light 
spots against the other more dark-coloured surface of the body. 
Fig. 19. Anterior part of the body in oil to show the simply branching in- 
testinal coeca, the brain area, and the cerebral eyes. Dorsal side 
upwards. 
Fig. 20. The whole animal in cedar-wood oil. a and b indicate anterior and 
posterior end respectively of pharynx; eb, excremental balls in the 
intestine. Ventral side turned upwards. 
Fig. 21. Ventral aspect of the animal in alcohol. Through the mouth pro¬ 
trudes a small part of the pharyngeal fold. The location of the gen¬ 
ital openings indicated, as they were clearly visible on the original 
photograph with the help of lens-magnification.

Fig. 22. Part of a longitudinal section through the body to demonstrate the 
male and female apparatus. The cyanophile secretory giands around 
the prostatic vesicle carry their secretion to the antrum and empty 
especially on the dorsal wall of it. This part projects as a heavy 
prominence and obviously corresponds to a penis. The secretion 
partly filis the antrum and the epithelium of the penis-like body. 
Its extreme affinity to hematoxylin makes it appear so black.

Fig. 23. Part of a transverse section of the body showing a retracted tentacle. 
The thick muscle wall of the body disappears at the border of the 
tentacle. The thick basement membrane thins out at the same time
