are groups of "yellow cells," Zooxanthella} which give the whole a 

 brown colour. Towards the Exumbral surface there are clouds of 

 strongly refracting minute bodies in the gallert, which give our 

 animal the spotted appearance, from which I have derived the 

 specific name. The suctoi'ial crisps are bi-own. The long stalked 

 suction naps (Peitschen filamente) are coloui-less and transparent. 



Size : Breadth of Umbrella, 500 mm. Thickness of Exumbrella, 

 50 mm. Mouth-arms, 300 mm. Filaments, 200 mm. long, and 

 at the base 10 mm. thick. 



Ontogenesis : The young embryos adhere to the mother's 

 filaments until they have nearly attained the scyphystoma stage. 

 The ephyra is brown spotted. The young medusa goes through a 

 complicated metamorphosis, passing through stages with 24 and 

 16 marginal bodies. 



Locality : Port Jackson. Von Lendenfeld. 



Family. Craynbessidce. 

 Discomedusse, without central mouth and tentacles, with a 

 single central sub-genital porticus and with dorsal and ventral 

 suctorial crisps and 8 mouth-arms. 



Genus. Cramborhiza. 



Crambessidge with free strong upper arm, and strong, triangular- 

 pyramidal under-arm, the 3 pinnate wings of which possess 

 numerous long filaments between the corymbiated suctorial crisps. 



Species. Cramborhiza flagellata. 



Haeckel, System der Medusen. Seite, 676. 



Umbrella slightly vaulted, hat-shaped, with 48 marginal flaps. 

 In each Octant 4 broad, oval, velar-flaps, between 2 small triangular 

 ocular flaps. Exumbrella finely granulated. Ostia of the sub- 

 gential-porticus 3 times as broad as the 4 perradial pillars between 

 them. Arms about as long as the radius of the Umbrella. Upper 

 arm strong, cylindrical, about as long as the triangular pyramidal 

 under arm, the 3 broad wings have strong flapped suctorial crisps, 

 and numerous Ions filaments.
