    Acoording to Marina Orio's table in "Cataclysmic Variables" p.429 (1995,
Kluwer Academic Publishers) and some other literatures, following Magellanic
and Galactic SSS's are listed.

    Unfortunately this list contains neither precise coodinates, nor Draco
C-1, though the object is rather familiar among northerners (as an extra-
galactic symbiotic star reachable by amateur telescopes).  Is there any
catalog of SSS's like Ritter's or Downes & Shara's in CVs?
