The connection between the arrival directions of ultrahigh energy cosmic rays by using the EAS array data and point galactic sources of radio-and gamma-radiations, pulsars,is sought. At the mean particle energy of 10¹⁹ eV the correlation between the particle arrival directions and pulsars located along the magnetic field lines has been found. According to our estimations the chance probability is equal to 2.10⁻⁴. The observed particle flux from 16 pulsars inside a circle of radius <6∘ exceeds the background by 6.3σ(p < 10⁻¹⁰), from PSR 2351+61 - 5σ. A group of 9 pulsars has been found from the direction of which the particle flux in the region 10∘×60∘ is in excess of the expected one by 4.4σ. The obtained results are discussed.
