Query: Followup Observations of SDSS and CRTS Candidate Cataclysmic Variables
  II   Spectra of 38 candidate or known cataclysmic variables are presented. Most
are candidate dwarf novae or systems containing possible highly magnetic white
dwarfs, while a few (KR Aur, LS Peg, V380 Oph and V694 Mon) are previously
known objects caught in unusual states. Individual spectra are used to confirm
a dwarf nova nature or other classification while radial velocities of 15
systems provide orbital periods and velocity amplitudes that aid in determining
the nature of the objects. Our results substantiate a polar nature for four
objects, find an eclipsing SW Sex star below the period gap, another as a
likely intermediate polar, as well as two dwarf novae with periods in the
middle of the gap.
