PLATE XI. 



The figures of this Plate were painted by nie from living specimens, which I observed in the 

 Canary Island Lanzerote, December 29, 1866. 



Athorybia ocellata, n. sp. (p. 276). 



Fig. 1. Lateral view of the complete corm, in an expanded state, quietly floating at the 

 surface of the sea (xy). The pneumatophore (p) bears a red pigment-cap and 

 is surrounded by a corona of crescentic elegantly ribbed bracts (b). Between 

 these are numerous prominent palpons (q), with a red ocellus on the apex (qo). 

 Below depend five siphons and tentacles ; ss, suctorial disc of the mouth.
