Resumen:
We present a number of neutral hydrogen supershells (SC-HI) found in the outer part of the Galaxy (80 l 130 and -50 b 50 ). These struc- tures were indentified through visual inspection of the neutral hydrogen data cube and will be part of a catalog, which will complement the existing ones (Heiles 1979, McClure-Griffiths et al. 2002). We have only catalogued those structures whose linear diameters, at the SC-HI´s kinematic distance, exceeds 200 pc. Using a least square method we have characterized the ellipse that best fits each structure.
