  Briceno et al. recently used optical imaging, data from the Two-Micron
All-Sky Survey (2MASS), and follow-up spectroscopy to search for young low-mass
stars and brown dwarfs in 8 square degrees of the Taurus star-forming region.
By the end of that study, there remained candidate members of Taurus that
lacked the spectroscopic observations needed to measure spectral types and
determine membership. In this work, we have obtained spectroscopy of the 22
candidates that have A_V<=8, from which we find six new Taurus members with
spectral types of M2.75 through M9. The new M9 source has the second latest
spectral type of the known members of Taurus (~0.02 M_sun). Its spectrum
contains extremely strong emission in H_alpha (W~950 A) as well as emission in
He I 6678 A and the Ca II IR triplet. This is the least massive object known to
exhibit emission in He I and Ca II, which together with the strong H_alpha are
suggestive of intense accretion.
