ZOOLOGY. 



Chitonactis coronata (Gosse) on the Dublin Coast. 



Irish records for this elegant little sea-anemone appear to be confined 

 to those given by Miss Jane Stephens in her " List of Irish Coelenterata " 

 {Proc. R. I. Acad., 1905) for our south-west coast, where it has been 

 taken three times in from 50 to 200 fathoms. The species occurred to 

 me quite unexpectedly in a shallow-water dredging in 8 f. off the mouth 

 of Bullock Harbour, Dublin Bay, on the 24th September last. Eight 

 specimens, five of them quite juvenile, were taken. They ranged from 

 3 mm. to 25 mm. in length when expanded, and were detected one by 

 one within 48 hours after the dredged material had been brought home, 

 and while I was searching through it for nudibranchs. In its unexpanded 

 state, when it is coated with a rough tawny epidermis, the species is 

 easily passed over as a form of simple Ascidian. Once this epidermis 

 is shed, however, and the rosy salmon-coloured column is extended 

 and crowned by its %vTeath of brown -barred tentacles even the smallest
