In 1895, dui'ing April and May, three specimens were taken ; 

 one was an early stage, about 2 mm. in length ; the others 

 were adults, the largest 20 mm. in diameter. 



In 1896, only a very early stage was taken in August. 



In 1897, it first appeared in April and disappeared in 

 October ; abundant throughout the summer. 



In 1898, it first appeared in July and disappeared in October; 

 abundant dui'ing July and August. The largest specimen 

 measured 22 mm. in diameter.

In 1896, it was only taken on three occasions during my visit 

 in the summer ; a single specimen on July 22nd and August 

 19th; and it was common just outside the harbour on August 

 10th. 



In 1897, it was not seen by the Misses Delap. 



In 1898, it only occurred in July. Pour large specimens 

 taken with ova along the whole length of the peduncle. Diameter 

 of the umbrella 10-12 mm. 



Under SapJienia miralilis I have commented on the probable 

 relationship of that Medusa with this species.
