Abstract
A total of 334 Low Surface Brightness galaxies detected in the 2MASS all-sky near-infrared survey have been observed in the 21 cm HI line using the Nancay telescope. All have a Ks-band mean central surface brightness, measured within a 5 arcsec radius, fainter than 18 mag/arcsec2 and a Ks-band isophotal radius at the 20 mag/arcsec2 level larger than 20 arcsec. We present global HI line parameters for the 171 clearly detected objects and the 23 marginal detections, as well as upper limits for the undetected objects. The 171 clear detections comprise 50 previously uncatalogued objects and 41 objects with a PGC entry only.
