Note: the top part of the table lists sources showing variability in ${\it JHK}$ whereas the bottom part lists
objects variable in two bands only.
$^{a}$ IAU designations include J2000 (RA, dec.) coordinates from UKIDSS GCS DR4\@.
$^{b}$ Weak H$\alpha$ detection reported by \citet{weaver04}.
$^{c}$ M4 with detection of lithium and H$\alpha$ equivalent width of 28\AA{} \citep{zapatero02c}.
$^{d}$ M1082188 and M1583183 were reported for the first time by \citet{caballero08c} as photometric member candidates.
$^{e}$ M5 with lithium, H$\alpha$~emission and disk \citep{kenyon05}; no Pa$\beta$/Pa$\gamma$ but HeI detected \citep{gatti08}. Faint companion detected on the GCS images.
$^{f}$ M2 with disk, X-ray emission, HeI, lithium but no Pa$\beta$/Pa$\gamma$ \citep{sacco08,gatti08}. Faint companion detected on the GCS~images.
$^{g}$ Presence of disk reported by \citet{hernandez07} and \citet{caballero08c}.
$^{h}$~M6, H$\alpha$ emission and presence of disk. Reported to be variable by \citet{caballero04} with detailed discussion in \citet{caballero06a}.
