We discuss the Seyfert galaxies in the Revised Shapley-Ames catalog
(BT < 13.31) and in three extensions to it (BT
< 13.4). The sample contains 91 relatively nearby Seyfert galaxies.
The proximity of the objects reduces the dilution of their nuclear
spectra by the host galaxy light. As a consequence, biases against
low-luminosity nuclei (relative to the host) and against edge-on
galaxies are reduced compared with other samples of Seyfert galaxies.
From this sample, we set a lower limit of 5% to the portion of galaxies
with Seyfert nuclei; completeness arguments could support a percentage
as high as 16%. We find type 2 Seyfert nuclei (i.e., types 1.8 + 1.9 +
2) to be 4 times more numerous than type 1 ones (types 1 + 1.2 + 1.5).
Seyfert nuclei of types 1 + 1.2 + 1.5 are mostly found in face-on
galaxies, while intermediate nuclei of types 1.8 + 1.9 are mostly found
in edge-on hosts. These results suggest that most of the intermediate
type Seyfert nuclei are type 1 nuclei seen through a 100 pc-scale torus
coplanar with the galactic disk and not type 1 nuclei partially obscured
by an inner parsec-scale torus.
