their brethren from some oyster bed. All the varieties mentioned by Gosse, 

 save Flava, occur in Ireland. Though on the east coast I have never 

 met with large specimens between tide-marks, yet on the west coast, 

 where the rocks are exposed to the swell of the Atlantic, I have taken 

 individuals three inches in length some distance above low-water mark. 



Scgphia {Sagartia) bellis. {Ellis.) 

 This species occurs from Londonderry, on the north, to Achill on 

 the north-west, and will doubtless be found in the intervening district, 

 when duly examined. In some parts it is found in great profusion, 

 especially in the fissures of the Devonian slates on the south-west. In 

 July, 1858, when at Roscarbery, county of Cork, Professor J. Reay 

 Greene and I found a very pretty variety of this species, which, I think, 

 is not described in the " Actin.Brit." For some time we imagined it was 

 a new species. The expanded disk was divided into a series of com- 

 partments, six of which were of a white colour, and six of a dark brown, 

 with a row of pure white spots around the mouth. It was very nume- 

 rous, but exceedingly hard to detach. 



Sagartia miniata. (Gosse.) 



This fine species was first discovered by me as Irish in the autumn 

 of this year in Crookhaven, county of Cork, and since then I have found 

 it at Berehaven, county of Cork, and Dingle, county of Kerry. In this 

 latter locality the variety Coccinea occurred. I think this species has 

 been passed over by me in some other parts of Ireland as one of the va- 

 rieties of S. rosea. 



Sagartia rosea. (Gosse.) 



This species occurs all around the south and west coast. The first 

 locality I found it in was near the charming village of Adragool, county 

 of Cork, on the borders of Bantry Bay — a pleasant day's excursion by 

 water from Glengariff. I think it is quite a distinct species from 

 Miniata ; and though varieties of each approach each other very closely, 

 yet I have not yet seen a specimen that I could not, without difficulty, 

 assign to its proper species. 



Sagartia omata. (Uoldsworth.) 

 Of this species, which would appear to be very rare in England, being 

 only as yet recorded as occurring at the entrance to Dartmouth Harbour, 

 I found several specimens at the mouth of Crookhaven Harbour
