  A total of 367 Low Surface Brightness galaxies detected in the 2MASS all-sky
near-infrared survey have been observed in the 21 cm HI line using the Arecibo
telescope. All have a K_s-band mean central surface brightness, measured within
a 5 arcsec radius, fainter than 18 mag/arcsec^(2). We present global HI line
parameters for the 107 clearly detected objects and the 21 marginal detections,
as well as upper limits for the undetected objects. The 107 clear detections
comprise 15 previously uncatalogued objects and 36 with a PGC entry only.
