PLATE III. 



Rhodalia miranda, n. sp. (p. 302). 



Fig. 13. Lateral view of the corm (from the left side), somewhat diagrammatic. 

 The triple corona of nectophores may exhibit in the living animal a 

 somewhat different form ; all the nectophores of the spirit-specimens 

 examined were strongly contracted and altered by the action of the 

 alcohol ; the majority, too, were detached from the stem. The 

 siphons and tentacles were all detached from the trunk, also very 

 highly contracted, and it is probable that they exhibit in living 

 specimens a larger size and a more peculiar form. The upper half of 

 the figure exhibits the nectosome from the left side ; most necto- 

 phores in the right half of the figure are removed, in order to show 

 the high insertions of their lamellar pedicles. Beyond the cap-shaped 

 apical pneumatophore the dorsal aurophore is visible on the right 

 hand. The lower half of the figure exhibits the siphosome, densely 

 covered with numerous cormidia, each with a contracted siphon, 

 a long tentacle, and a clustered gonodendron (compare p. 290), 



Fig. 14. Dorsal view of the same corm. The majority of the nectophores are 

 removed from the trunk of the nectosome, the high insertions only 

 of their lamellar pedicles being visible. A few nectophores remain 

 on the right and left. Beyond the cap-shaped apical pneumato- 

 phore is visible in the median dorsal groove of the trunk the 

 spheroidal aurophore, with its external opening, the aurostigma. 

 The trunk of the siphosome (in the lower half of the figure), and 

 the numerous cormidia covering it, are highly contracted ; all the 

 tentacles are detached ; between the clustered gonodendra are 

 visible the strongly retracted siphons, ....
