The present catalogue is the last one of the four catalogues published according to programme of Abastumani Astrophysical Observatory of a massive two-dimensional MK classification of stars in 115 kapteyn Select Areas (KA) of Northen Sky. The catalogue lists the spectral types and luminosity classes for 3880 stars in 23 Kapteyn areas 92-115 through the declination circle of 0{deg}. KA 95 was skipped because of poor quality of observational data. The catalogue is compiled on the basis of the spectral data obtained with the 70-cm meniscus telescope of Abastumani Astrophysical Observatory using the 8{deg} objective prism (dispersion 166{AA}/mm near H{gamma}; in the short-wave region, the spectrum extends up to 3500{AA}). The field of the meniscus telescope is 4.5{deg}x4.5{deg}. The photo material is taken on Kodak IIa-O, hyper-sensitized Kodak IIIa-J and in order to detect also H{alpha} emission stars and M, S, C type stars in the surveyed KA's, hyper-sensitized Kodak IIIa-F plates were also taken. A limiting apparent magnitude in V for stars in question is 12.5 photographic mag. and for M ones - 15.0mag. The data for all KA's are uniform not only in the sense of classification accuracy (the whole classification is done by one person - the author of the present catalogue), but also in the sense of penetration. The errors of our determinations are: +/-0.6 for spectral subtype and +/-0.5 for luminosity class. The stars in the KA's are arranged in the Catalogue by increasing right ascension. The stars are numbered according to zones of 1{deg} in declination. The printed catalogue is provided with suitable stellar charts for separate KA's reproduced from the Lick Catalogue. The reference system on the charts refers to 1950 epoch and it is plotted according to the Smithsonian Astrophysical Observatory (SAO) catalogue.
