We report on spectroscopic observations of two ATLAS discovered transients. Spectra were obtained on March 26+27, using ACAM+R400V on the 4.2m William Herschel Telescope in La Palma, Spain. AT2016BEV was previously classified as a type II SN (ATel #8856); we obtained a higher SNR spectrum and confirm it is a young type IIP SN. The spectrum has a clear deficit of flux in the blue, indicating it is significantly reddened along the line of sight (it is located ~3 degrees from the Galactic plane). The spectrum also displays strong narrow NaD absorption lines consistent with a large extinction. AT2016BHR (ATel #8857) is a type Ia SN close to the core of its host galaxy.
