The aim of this work was to derive the elemental abundances in four stars classified as semiregular variables of the type ``d'' (SRd). These stars should presumably belong to the Galactic halo population. Elemental abundances have been derived from both local thermodynamical equilibrium (LTE) and non-local thermodynamical equilibrium (NLTE) analyses, applied to high-resolution (R≃80000) spectra obtained with the CFHT ESPaDOnS spectrograph. We have derived the abundances of 29 chemical elements in V463 Her, V894 Her, CW CVn, and MS Hya, and arrived at the following conclusions. The stars of our programme have a chemical composition that does not agree with their presumable status as metal-deficient halo giants. All studied SRd giants have relative-to-solar elemental abundances typical of the thick/thin Galactic disc stars.
