BRITISH PALEOZOIC ASTEROZOA. 



I am indebted to Mr. W. B. Wright, the Senior Geologist of the Irish Geological 

 Survey, for the following remarks npon the horizon and locality of this species : 

 " Mr. Clark tells me that all the specimens of U. Icinahani are from the same 

 locality, namely the townland of Loftus-Acre, 700 yards west of Ballymadder Point, 

 County Wexford. The whole townland has since been removed by the sea, and 

 the rocks in which the fossils were found are no longer exposed. As regards the 

 Ballymoney series, I cannot find any ground for supposing the rocks in question 

 belong to this series, which is stated in the Memoir only to occur in the N.E.

corner of sheet 169. The following considerations n)ay be of use in fixing the 

 horizon : (a) The rocks on the shore in the neighbourhood of Loftus-Acre have a 

 general westerly dip, and 700 yards to the east, at Ballymadder Point, they rest 

 unconformably on metamorphosed Cambrians ; bh) the locality also yielded Glijpto- 

 crinus hasalis ? and DicnnKxjva'ptns ramosvs. Mr. Clark tells me that the latter is 

 a typical Lower Caradoc or Upper Llandeilo form, and on consulting Miss Elles's 

 Monograph, pp. 518 — 527, I find that she refers this species to the same horizon." 

 Mr. Wright also adds that the Survey originally possessed forty-four specimens of 

 the species.
