SPECTRAL TYPES IN THE PLEIADES.

New spectral classification of 49 of the brightest stars in the Pleiades shows the following peculiarities: (1) three ApSi stars, of which one is a member of a 2d46111 double4ined binary with an Am secondary, (2) an Ap(Hg,Mn) star that may be a member of the cluster, (3) four Am stars, of which two are only marginally abnormal, and (4) three shell spectra that include the pronounced case of Pleione and two mild shell spectra called "sn". The Ap + Am system should be checked for eclipses. Key words: open clusters-peculiar stars-spectral classification
