Figs. 1-12. Cymbonectes huxleyi, n. sp. (p. 134). 



The entire corm with expanded stem. From the hydrrecial groove of the single nectophore 

 proceeds a long tubular stem, which bears eight or nine well-developed diclinic cormidia, 

 alternating males and females. The signification of the characters is the same as in 

 figs. 2-4,

Ventral view of the nectophore. a, Apical part of the trunk ; n.r, right wing, nl, left win: 

 of the ventral side of the exumbrella, protecting the hydrcecial canal,

Figs. 9-12. Four different larval stages {Calyconula) of Cymbonectes hvxleyi, arising from the 

 fertilized egg. Each larva is a single medusome, the manubrium of which (or the primary 

 siphon, g) has been protruded through the ventral fissure of the umbrella (or the primary 

 nectophore, n). e, Exoderm ; d, entoderm ; t, tentacle ; w, subumbrella ; />, velum,
