suggest, that on reading over Miiller's brief description, so different from 

 those we are now accustomed to, I think his Undata is not a variety or 

 a synonym of the present species. 



Cylista (Sagartia) parasitica. (Couch.) 



This species would appear to be quite absent from the eastern 

 shores of Ireland, and I only know of its being taken once in Ireland, 

 in Bantry Bay. The specimens then taken lived for a long time in one 

 of the large aquaria in the Gardens of the Royal Zoological Society. 



Sagartia (Thoe?) hastata (n. *.). 



This, which is apparently a new species, occurred in some numbers 

 off The Pipers, a dangerous cluster of rocks near the western entrance 

 of Berehaven Harbour. I was struck by the curious arrangement of 

 the tentacles, which put me in mind of a battalion of Roman soldiers 

 armed with spears. They were, when fully expanded, arranged close 

 to each other, showing but little of the disk, the orange-coloured mouth 

 being all that was generally visible, and closely resembling a thicket of 

 spears. They were attached to the sides of rock-pools, and it was not 

 very difficult to detach them, in this resembling T. sphyrodeta. The fol- 

 lowing is a diagnosis of the species, of which, I am sorry to say, I am 

 unable to give figures, as the specimens sent to Mr. Gosse died in transitu; 

 the weather (August) was very warm, and from Berehaven it is three 

 days' postage to Torquay.
