The absolute sea-level cosmic-ray muon intensity has been estimated by using a flash-tube range spectrograph at axial zenith angles 75 degree--85 degree W near the geomagnetic equator in the cutoff-momentum region 0.4 GeV/c. The measured absolute muon intensity agrees with the results calculated in the manner of Ashton et al., assuming K/$pi$ = 0 for zenith angles up to 81 degree W and K/ $pi$ = 0.4 for 85 degree W. The angular distribution of muons obeys a cosine- square law. The measured absolute integral muon spectrum at axial zenith angle 81 degree W in the cutoff-momentum interval 0.4--3 GeV/c agrees with the theoretical spectral shape calculated in the manner of Barrett et al.
