 DiSTEPHANUs ACULEATUS (Ehrenberg). 



Dictj/ocha aculeata, Ehrenberg (1839). 

 Distiphanuti aculcatns, Hteckel (1887) 



Specimens that were referred to this species, with a query, by Sir J. W. 

 Dawson (in his Handbook of Zoology, published in 1870) ai'e said to have 

 been "obtained from a depth of 31. 'i fathoms in the Gulf of St. Lawrence 

 by Captain Orlebar, R.N." Similar specimens have since been found by the 

 wn'iter in a sponge (Ifalichondria panicea) and in the stomach of the common, 

 sea urchin [Stronglocentrohos drobaddensis), both from very shallow water 

 off Cap des Rosiers. 



Three or four additional species of radiolarians are now known to occur 

 in the Gulf of St. Lawrence, but they have not yet been critically studied.
