Mass differences between octet strange baryons, octet and decuplet strange baryons, and nonet vector mesons and octet baryons of equal strangeness coincide (within the small experimental uncertainties) with the levels of a recently proposed hadron mass spectrum. A number, M, characterises the mass difference in relation to the strange quark mass of the spectrum. The mass diference of Lambda and Sigma0 (delta I=1) is characterised by M=+1. The mass difference of Sigma0 and Sigma(1385)0 (delta J=1) is characterised by M=-1. Vector meson-baryon (delta J=1/2) mass differences are characterised by M=-1/2. The mass differences of strange decuplet baryon resonances (delta S=1) are characterised by M=-2 and M=-3, where M is equal to the strangeness of the more massive baryon.
