SCYPHOMEDUSJG OF THE AUSTRALIAN SEAS. 23 



Genus PHYLLOPvHIZA. L. Agassiz, 1862. 



"With eight pinnate mouth-arm.?. The pinna; rudimentary and connected 

 by a membrane, so that the whole arm attains an extended leaf-shaped appear- 

 ance. Continuous sub-genital porticus. Brachial disc completely divided 

 from the umbrella.

The umbrella is nearly semi-spherical, and about half as high as broad. 

 The umbrella margin bears in every octant two sickle-shaped ocular flaps, 

 four simple and four double flaps, all of which taper centrifugally and are 

 truncate. These flaps consist of thick gallert, and are connected by thin 

 membranes. Radial furrows extend centripetally from the fissions towards 

 the centre of the disc. The sub-genital ostia are large and oval, more than 

 twice as broad as the pillars of the brachial disc. The brachial disc is thick 

 and a little more than half as broad as the umbrella, octagonal, with a 

 canal system of its own, and thickly set on its ventral side with filaments, to 

 which the young gastrula?-embryos adhere. The mouth-arms are f as long as 

 the diameter of the umbrella. 



Colour. Brachial disc, stem and branches of mouth arms, and also the 

 ground substance of the umbrella, colourless. In the gallert of the umbrella, 

 close to the surface, 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 

 suctorial crisps are brown. The long-stalked suction naps (Peitschen filamente) 

 are colourless and transparent. 



Si.~e. Breadth of umbrella, 500 mm. ; thickness of ex-umbrella, 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.
