   • 1993, George R. Zug, Herpetology: An Introductory Biology of Amphibians and Reptiles, page 427,

     Lacertid scalation and body forms are similar to those of the teiids, although lacertids are usually smaller.

   • 2004, Daniel A. Greenberg, Lizards, page 33,

     Lacertids are distinguished by a section of large, flat scales on the undersides of their necks. […] Teiids are the New World counterparts to lacertids.

   • 2006, Eric R. Pianka, Laurie J. Vitt, Lizards: Windows to the Evolution of Diversity, page 206,

     Lacertid teeth are hollow at the base (teiid teeth are solid). Virtually all lacertids are terrestrial or rock-dwelling lizards, although a few species, including Holaspis and Takydromus, climb in vegetation, and at least one species appears to live high in trees.

   • 1990, Bulletin of the Special Astrophysical Observatory-North Caucasus, Volumes 24-26, page 67,

     These reliably variable objects included three ROCOSs (OE 400, OI 090.4, and PI034-293) and two lacertids (AO 0235+164 and OJ 287).

   • 1993, Astronomy Reports, Volume 37, Pages 329-688, American Institute of Physics, page 466,

     We have identified six radio sources in the Zelenchuk (RATAN-600) catalog with two quasars, two lacertids, and two pairs of galaxies.
