Dr. Baird {loc. cif.) records this species from " Berwick 



Bay, 1835, not common." Otherwise it does not appear to 



have been noticed in our district, and partly on this account 



we have heretofore taken Baird"s species to be that here called 



Eiipclfe purpuroctncfcu But his description, and especially 



his figures, seem more properly applicable to the present 



species, and that view has also been taken by so good an 



authority as Professor Claus. N.
