We carried out a 2MASS J, H and K_s survey of infrared star clusters in the
Milky Way sector 230$^{circ}$ $< ell <$ 350$^{circ}$. This zone was the
least studied in the literature, previously including only 12 infrared clusters
or stellar groups with $|b|<$ 10$^{circ}$, according to the recent catalogue
by Bica et al. (2003). We concentrated efforts on embedded clusters, which are
those expected in the areas of known radio and optical nebulae. The present
study provides 179 new infrared clusters and stellar groups, which are
interesting targets for detailed future infrared studies. The sample of
catalogued infrared clusters and stellar groups in the Galaxy is now increased
by 63%.
