A comparison of the Valencia specimens with the description 

 given by Haeckel, shows that the umbrella is a little smaller, 

 and that there are a few more lobes and tentacles. The lobes 

 are not twice as long as broad, but only slightly longer. The 

 lobes increase in number by longitudinal division, so that they 

 are not all of the same shape, some being much broader than 

 others. The sense-organs were of a pale yellowish colour; 

 they varied from one to three in number on each lobe, but more 

 than three together were never seen. The genital band agreed 

 with Haeckel's description. In most of the specimens it was 

 on the outer half of the stomach, but in a few it extended over 

 the outer two-thirds. In specimens about 3 mm. in diameter 

 the generative cells were just visible, and nearly ripe in speci- 

 mens of about 6 mm. in diameter. 



Solmaris corona has only been recorded from Naples.

Order. — Discomedits^. 

 Aurelia atirita (Linn.). 



In 1895, a few adult specimens were seen during June. 



In 1896, a single Ephyra was taken on February 14th. The 

 adult form was not seen in the harbour during the year. (Miss 

 C. Delap saw a great quantity of large adult specimens ofp 

 Fenit Pier, Tralee Bay, in May.) 



In 1897, six Ephyrae were taken on January 14th, and a few 

 in February. Some adult specimens seen in the harbour during 

 July.
