Explanation of the Plates. 
Plate III. 
Stylochus niarmoreus n. Sp. 
Pigs. 1 — 6. 
Fig. 1. Dorsal view of the body of the smaller specimen. 
Fig. 2. The type-specimen in dorsal aspect, 1, 3 x. 
Fig. 3. Part of body to demonstrate the patches of pigment. 2, 6 x. 
Fig. 4. The same specimen as in Fig. 1 in cedar-wood oil. On account of 
the rich pigmentation, the interior organs are not traceable on this 
photograph taken from above. Filled as they are with eyes, the 
tentacles appear as black spots; they are otherwise pigment-free. 
Fig. 5 The type-specimen in cedar-wood oil, ventral side turned upwards and 
the light passing through. The branched uteri filled with eggs are 
discernible. The upper ph indicates the part of the pharyngeal fold 
which protrudes like a rosette through the mouth, the lower ph the 
pharyngeal pocket prolonged backwards as a very long median- 
placed diverticle. 
Fig. 6. Brain-area {br) and tentacles (t) of the type-specimen. 
Kaburakia excelsa n. g. n. sp. 
Figs. 7 — 10. 
Fig. 7. Ventral view of the largest specimen. The pharynx protrudes as 
an extremely folded rosette through the mouth. 
Fig. 8. Dorsal view of the same specimen to demonstrate the distribution 
of the pigment. 
Fig. 9. The smaller form (f. minor) in dorsal aspect. The specimen is sex- 
ually ripe. 
Fig. 10. The type-specimen in dorsal aspect. 
Leptostylochus elongatus n. g. n. sp. 
Figs. 11 —16. 
Fig. 11. The largest specimen in cedar-wood oil. 
Fig. 12. The type-specimen in cedar-wood oil, with the ventral side upwards. 
Fig. 13. The same in alcohol.
