246 THE SCYPHOMEDUS^E OF THE SOUTHERN HEMISPHERE, 



Umbrella nearly quadrangular-prismatic, stubbed at the top, 

 more than J as high as it is broad. Gastral cavity nearly 

 globular, occupying the upper half of the Sub-umbrella-cavity. 

 Twice as high as the infundibuliform mouth-tube, which is split 

 below into 4 short triangular mouth-flaps ; 4 Phacellte simple 

 interradial rows of thread, which pass through the upper § of the 

 Gastral side of the cavity. Velarium broad, with numerous 

 dendritic ramified canals. Pedalia in the form of clubs, twice 

 as long as broad, about £ as long as the height of the Umbrella, 

 spreading towards the base, two winged with broad meridial- 

 wings. 



Size : Breadth of Umbrella, 120 mm. Height, 150 mm- 

 Ontogenesis unknown.

Umbrella semi-spherical, the upper third curved, the other 

 thirds cubic, \\ as high as broad. The semi-spherical cupola and 

 the 9 quadratic side-surfaces are papillous, sprinkled with large 

 nettle-knobs. The 4 corner pillars, half as broad as the side-surfaces, 

 are divided into two parts by a deep furrow, and longitudinally 

 finely ribbed. Margin of Umbrella only slightly thickened, 

 divided into many triangular prismatic ridges by deep cuttings. 

 From which 6 — 8 are on each of the 4 side-surfaces. 



Pedalia oval, three-cornerd, l£ as long as the sub-umbrella 

 cavity, the dorsal margin wing-shaped, rising from the margin 

 of the Umbrella. 



Size : Breadth cf Umbrella, 70 mm. ; height of Umbrella, 

 100 mm. ; Ontogenesis unknown. 



Locality : New Guinea, Kawack. Waigion. Lesson.
