BROWNE— SOME JELLY-FISHES FROM OKHAMANDAL IN KATTIAWAR 155 



The specimens from Beyt Bay agree with the variety from the Maldives in having 

 no trace of colour-markings upon the umbrella, in having a circular band upon the 

 ex-umbrella, used as a pad for holding the medusae fast by suction when lymg on its 

 back, and in the length and shape of the oral arms. There are no conspicuous, extra 

 large, band-shaped appendages on the oral arms as found in the typical specimens from 

 the Maldives. Some of the specimens have band-shaped appendages, but they are 

 not more than 12 mm. in length and' 3 mm. in width. 



Cassiopea has a very wide geographical range throughout the tropics, and lives in 

 shallow bays and lagoons. It is rather tied to definite locahties by having to pass 

 through a fixed scyphistoma stage in the course of its hfe-history. It is also a variable 

 medusa, and the finding of a Cassiopea in a new locahty usually means the finding of 

 a new race, called either a variety or species, or a doubtful association with a variety 

 already named. The only method for satisfactory work on the species and varieties 

 of this genus is the examination of a very large number of specimens from each locality.
