20 DESCRIPTIVE CATALOGUE OF THE 



Umbrella slightly vaulted, semi-spherical two or three times as broad as 



high. Ex-umbrella set with warts, covered with pointed elevations. Mouth- 

 arms tender, richly folded curtains, about as long as the radius of the 



iimbrella. The margin of the umbrella has sixteen small incisions of which 

 the eight ocular incisions are deeper than the eight tentacular ones, sixteen 

 flaps quadrangular, truncate. There are five very large tentacles on the 

 ventral side of each main flap, they are ten times as long as the diameter of 

 the umbrella. 



Colour. Pink, margin of umbrella and tentacles, darker. 



Size. Breadth of umbrella, 200 mm. height of umbrella, 100 mm.; length 

 of tentacles, nearly 2 metres. 



Locality. Port Jackson, Sydney, Quoy and Gaimarcl. 



Genus CYANEA Peron et Lesueur, 1809. 



Cyanidre with eight marginal bodies and numerous tentacles which form 

 eight bundles of in the tertiary radii on the sub-umbrella. There are several

The umbrella flaps are rounded and not broader at the end than at the 

 base. Every main flap (Ephyra-arm) consists of four flaps, two smaller 

 ocular flaps_and two larger flaps at the sides. The umbrella is 5 7 times as 

 broad as high, depressed, with a few protruding nettle-warts in the centre of 

 the ex-umbrella. 



Ontogenesis. The embryos hang on to the mouth-arms until they are nearly 

 matured to young Scyphystomte, and then affix themselves to bodies in the 

 water, producing a long stalk with a chitinous perisark and eight arms. The 

 Ephyra passes into the adult by a complicated metamorphosis. The umbrella 

 flaps are produced by fission.
