The osteology and myology of the head and neck region of Callisaurus, Cophosaurus, Holbrookia, and Uma, the "sand lizards"
Blainville (1835) wrote the first description of a sand lizard and named it Callisaurus draconoides. Since his time various authors have published articles concerning sand lizards. Girard (1851) described Holbrookia maculata, Trochel (1852) described Cophosaurus texanus, and that same year Baird and Girard synonymized Cophosaurus with Holbrookia providing the name Holbrookia texana, which has stood for over 100 years. Subsequently, Baird (1858) described Uma notata.
