It is pointed out that the assumption regarding the homogeneity of the universe, when considered over large scales, has had a powerful influence on modern cosmology. However, certain studies suggest the existence of elongated structures in the universe. Einasto et al. (1980) have emphasized the existence of the Perseus supercluster, a filamentary structure. A search has, therefore, been conducted for evidence of large-scale inhomogeneities in the local universe, taking into account the identification of a number of statistically significant extended structures. The present investigation is concerned with evidence collected with regard to one of such structures, located in the Lynx-Ursa Major region which, although still fragmentary, suggests the existence of a coherent supercluster filament heretofore unrecognized.
