The arcsecond radio structure of a complete sample of X-ray selected BL Lacertae Objects (XBLs) has been studied with the VLA (at 20 cm, A array). These maps reveal a variety of structures resembling Fanaroff-Riley type 1 radio galaxies of various types. Comparison of the absolute radio properties of XBLs with those of radio-selected BL Lacertae Objects (RBLs) and FR 1 radio galaxies reveal that: a) In general the extended radio powers and morphologies of XBLs and RBLs are consistent with being beamed FR 1 radio galaxies; b) the ratio of core to extended power (which is a measure of the amount of relativistic beaming) spans a greater range and has a higher mean for RBLs than for XBLs. The data for these samples suggest that the ratio gamma_ {RBL}/gamma_ {XBL} ~ 1.5. However, c) the radio-selected population is a more heterogeneous class than the X-ray selected population, including some beamed FR 2 sources and some strong gravitational lens candidates.
