PLATE XXXII. 



The figures of this Plate were drawn by me from living specimens, in the Canary Island Lanzerote, February 

 17-20, 1867, except the bract, fig. 9, and the tentillum, fig. 14, which were found in a bottle in the Challenger 

 collection from Station 352. 



Eudoxella galea, n. sp. (pp. 108, 148). 



(Monogastric generation of Praya galea, PI. XXXI.) 



Fig. 8. A single cormidium or eudoxome, sessile on the stem (a), composed of two medu- 

 somes or medusoid persons. The sterile medusome is composed of a helmet- 

 shaped or reniform bract (b), a siphon (s), and a tentacle (t). The fertile 

 medusome is a male gonophore (h), attached to the ventral side of the siphon 

 (s). The latter exhibits eight yellow hepatic ridges (sh) in the wall of its 

 stomach. The mouth (so) is closed. The bract (b) exhibits the four radial 

 canals of a medusome-umbrella, bilaterally developed, dorsal (cd), ventral (cv), 

 right (ex), and left (cl). They are connected by the bracteal canal (ca) with 

 the stem (a). The long tentacle (t) is articulated and beset with numerous 

 tentilla. 



Fig. 9. A single bract, with its four radial canals. Characters as in fig. 8 ; w, subumbrella. 



Fig. 10. A female gonophore. The ovarium (/) is suspended in the apex of the sub- 

 umbrella (iv). The bdateral umbrella exhibits a very large dorsal wing (nd) 

 and a smaller ventral wing (nv) ; v, velum. 



Fig. 11. A siphon, doubly invaginated. The basigaster (sb) is strongly expanded and 

 has taken into it the retracted stomach (sh) ; the cavity of the latter again 

 contains the basal part of the invaginated proboscis (sr). The mouth (so) 

 is closed. 



Fig. 12. A tentillum, seen from the convex dorsal side, km, Small median cnidocysts ; 

 hi, large lateral cnidocysts ; kp', kp", pyriform distal cnidocysts ; ts, pedicle ; 

 tf, terminal filament. 



Fig, 13. A tentillum seen from the left side. Characters as in fig. 12. 



Fig. 14. A tentillum, strongly contracted, from the right side. Characters as in fig. 12. 



Fig. 15. The first or apical nectophore of a young corm, with a bunch of numerous buds (i).
