152 OKHAMANDAL MARINE ZOOLOGY REPORT PART II 



The Anthomedusse were not represented at all, and the Leptomedusse had one 

 species : an Irene, but the specimens were too dilapidated for the determination of 

 its species. The Trachomedusee were represented by two species : Amphogona apstelni 

 and Liriope sp., which latter was fairly common, but the specimens were spoilt by the 

 mud. The Narcomedusse consisted solely of the well-known and widely-distributed 

 Solmundella bitentaculata. The Siphonophora belonged to two species, namely Diphy- 

 opsis chamissonis and Bassia bassensis (Quoy et Gaimard). The identification of Bassia 

 bassensis rests on the finding of four bracts belonging to its Eudoxid.

A single specimen was taken in December, 1905, off the coast between Rupan Bundar 

 and Kutchegad. 



The umbrella is conical, about 3 mm. in height and 4 mm. in width. The stomach 

 is on a short peduncle, and its mouth has four lips. There are eight radial canals, and 

 upon each one there are traces or remains of gonads which are situated about three- 

 quarters the distance down the canals. The tentacles are all broken off, but their stumps 

 indicate that there were twelve to fifteen in each octant. No sense-organs could be 

 found. 



The umbrella of this specimen is rather more highly arched, being higher in pro- 

 portion to its width, than usually recorded, and its tentacles are more numerous, but 

 I have no reasonable grounds for assuming it to be a new species. 



Amphogona apsteini has been previously recorded from the Maldives, from Sumatra, 

 and from Acapulco Harbour in Mexico.
