Nectalia loligo, n. sp. (p. 252). 



Fig. 1. Lateral view of the complete corm. The trunk of the nectosome bears an apical pneumatophore (p). 

 with pueumatocyst (pf), and two opposite rows of nectophores (w). The shortened trunk of the 

 siphosome bears a corona of bracts, and beyond it siphons («), palpons and tentacles (t); in, buds 

 of nectophores. 



Fig. 2. The same corm in the contracted state, after the detachment of the nectophores. pf, Pueumatocyst ; 

 in, buds of nectophores; is, buds of siphons; sb, basigaster; sm, stomach; sp, hepatic villi; 

 sr, proboscis ; so, mouth ; yh, cystons ; yo, their distal opening (anus 1). 



Fig. 3. The trunk alone, after the detachment of the appendages (lateral view from the left side), am, Necto- 

 style (trunk of the nectosome) ; p, pneumatophore ; pf, pneumatocyst ; in, buds of nectophores ; 

 as, vesicular siphostyle (trunk of the siphosome) ; is, buds of siphons and palpons. 



Fig. 4. The pneumatophore (much contracted in spirit), px, Apex ; pb, basis ; pf, pneumatocyst ; pr, four 

 radial septa ; ps, pouches between them ; in, buds of nectophores , am, trunk of the nectosome.

Fig. 11. Dorsal view of a lateral bract. Characters as in figs. 9, 10. 



Fig. 12. Lateral view of the same lateral bract. 



Fig. 13. A siphon, sb, Basigaster; sm, stomach, with hepatic villi (sv) ; sr, proboscis; so, mouth 



Fig. 14. A ten ti Hum (lateral branch of a tentacle), ts, Pedicle; tk 1: basal ampulla; f/fc, v , cnidoband ; tk u , 

 cnidosac ; //>' m , terminal ampulla ; tf, terminal filament.
