264 THE SCYPHOMEJDUS^E OF THE SOUTHERN HEMISPHERE, 



Genus. Linerges. 



Linergidse with 4 horse-shoe shaped interradial Gonads, the 

 convex proximal arches of which are divided into 2 adjacent wings 

 by an interradial median septum. On the Subumbrella a double 

 circle of 48 Subumbral-pouches (scrota 1 ?). 16 larger proximal 

 (under and between the Gonads), and 32 smaller distal (on the 

 upper margin of the circle of the muscle.) 



Species. Linerges aquila. 



Haeckel. System der Medusen. Seite, 496. 



Umbrella cap-shaped with horizontal Exumbrella, and nearly 

 vertical side-walls, 1^ times as bi-oad as high. Marginal flaps 

 oval, a little longer than broad. Flap canals broad, hand-shaped, 

 the longest (medial) half as long as the flap itself, in every flap 

 20-30 cul-de-sac shaped terminal branches. Tentacles cylindrical, 

 at their ends club-like, 1| times as long as the flaps. 4 Gonads 

 horse-shoe shaped, two- winged, both wings divergent, convex 

 margin flat, on the concave side deeply incised. 



Size : Breadth of Umbrella, 18 mm. Height of Umbrella, 

 12 mm. Ontogenesis unknown. 



Locality : Indian Ocean, to the East of Madagascar. Rabbe. 



Genus. Liniscus. 

 Linergidse with 8 separate adradial Gonads (ovarise) which are 

 curved sickle-shaped or rectangular, and approach with their 

 proximal ends, in pairs, in such a manner that they form a horse- 

 shoe shaped group. On the Subumbrella there is a double circle 

 of 48 Subumbrella pouches (scrota V). 16 larger proximal (under- 

 neath and between the Gonads), and 32 smaller distal (at the 

 upper end of the circle of muscles.) 



Species. Liniscus ornithopterus. 



Haeckel, System der Medusen. Seite, 497. 



Umbrella cap-shaped, with quite flat vortex and nearly vertical 

 side walls, 1£ times as broad as high. Marginal flaps oval, l 1 

 times as long as broad, covered with nettle-warts. Flap canals
