to any known species, as none belonging to the genus have been 
described with medusa-buds. 
The specimens were very much alike, but one was twice as 
large as the other. The umbrella of largest specimen about 1 mm. 
in diameter, globular, about as long as wide; at the aboral end 
there is a slight rounded swelling, formed by a mass of mesoglea. 
The manubrium reaches nearly down to the velum ; stomach large 
and situated upon a stout peduncle, nearly as long as the stomach ; 
mouth round, not divided into lips. Four medusa-buds upon the 
stomach (one bud nearly fully developed, the four tentacles visible 
with brownish basal bulbs). On the margin of the umbrella four 
tentacles, when fully expanded about twice the length of umbrella, - 
with blackish basal bulbs. At the free end of each tentacle a very 
large brownish bulb containing nematocysts. Nematocysts are also 
scattered along the whole length of each tentacle. Cells are present 
on the peduncle which may be nematocysts. The margin of the 
umbrella between the tentacles is nearly straight, giving a quad- 
rangular appearance, with a tentacle at each corner. Velum broad. 
Eupnysa AuRATA, Forbes. 
Euphysa aurata, Forbes (1848) ; Haeckel (1879) ; Holt (1891); 
Crawford (1891); Maas (1893) ; Browne (1895). 
Euphysa mediterranea, Haeckel (1879). 
Up to the present time this medusa has not been recorded from 
many localities. It had only been found in the northern portion 
of the British area until this spring, when I found it at Valencia. 
In the ‘ Report on the Medusz of the Isle of Man’ I have given 
a description of several specimens, and have shown that a great 
variation in colour occurs in some specimens, and that Huphysa 
mediterranea is only a brilliantly coloured form of Huphysa aurata. 
At Valencia this medusa was first taken on April 16th, 1895, 
and after this date it was often seen in the tow-net, especially 
towards the end of May, when it became more abundant. Most 
of the specimens belonged to the early stages, and were much 
smaller than any taken at Port Erin. 
The smallest specimens were about ? mm. in length, and the 
average-sized ones about 1-1} mm. in length. 
The shape of the umbrella, of the tentacle-bulbs, and of the 
large tentacle is similar in all the stages: thus there is no difficulty 
in identifying the earliest forms. The smallest specimens usually 
possess very little colour, a few are quite colourless, generally the 
tentacle-bulbs have a pale yellowish tint, but in a few specimens a 
bright yellowish colour existed. 
The specimens 2-3 mm. in length possessed more colour. One 
specimen 3mm. in length had yellowish tentacle-bulbs, with a 
deep orange-coloured centre. 
Many of the early naturalists described the pigmented basal 
bulbs as ocelli. I prefer to retain the term ‘ ocellus’ for definite 
eye-spots, as clearly seen in Sarsia, which also has pigmented 
basal bulbs. LJ
