(e-mail: [email protected]) Abstract. The purpose of this application is to conserve the usage of the subspecific names of Thamnophis sirtalis infernalis (Blainville, 1835) for the California red-sided garter snake (family colubridae) which is found along the Californian coast, and of T. s. tetrataenia (Cope in Yarrow. 1875) for the San Francisco garter snake from the restricted area of the San Francisco Peninsula. It is possible that the holotype of T. s. infernalis is a specimen of T. s. tetrataenia. formally rendering the name tetrataenia a junior synonym of infernalis. It is proposed that the holotype of infernalis be set aside and a neotype designated in accord with accustomed usage. Keywords.

In 1835 Blainville (pp. 291-292, pi. 26, figs. 3, 3a) described Coluber infernalis, a garter snake, from a specimen collected by Paolo Emilio Botta in 1827 or 1828 (Museum National d'Histoire Naturelle, Paris, catalog no. MNHN 846) from an indeterminate locality in California. Baird & Girard (1853, p. 26) and Bocourt (1892, p. 40) subsequently placed C. infernalis in Eutaenia Baird & Girard. 1853. Van Denburgh & Slevin (1918, p. 198) treated iifeniaUs as a subspecies of Thanmophis sirtalis (Linnaeus. 1758). and Fitch ( 1941 ) restricted the distribution of T. .v. infernalis to the Pacific coast region of California, based on Botta's supposed collecting sites and on consistent taxonomic differences between coastal and interior or northern T sirtalis.
