Gopherus agassizii (Cooper 1861:120)

Syntypes (3): “Three young specimens”, apparently originally in the California State Geological Survey collection according to Cooper (1861:120). The syntypes were later transferred to other collections, since USNM 7888 was listed by Cochran (1961:236) and Reynolds et al. (2007:32) as one of the syntypes. The identity of the other two syntypes is uncertain; one was apparently in the CAS and potentially destroyed in the 1906 earthquake and fire and the other is apparently lost (see discussions in Reynolds et al. 2007:30 and Murphy et al. 2011:44–45). USNM 7888 designated lectotype by Murphy et al. (2011:39; sampled genetically and photographed therein, p. 53–57, Figs. 4–8).

Xerobates lepidocephalus Ottley & Velázquez Solis 1989:497 .

Holotype: BYU 39706 (sampled genetically by Murphy et al. 2011); paratype (1), BYU 39707.
