Six species of colubrid snakes from California were examined for helminths: Arizona elegans, Chionactis occipitalis, Masticophis flagellum, Masticophis lateralis, Phyllorhynchus decurtatus and Rhinocheilus lecontei.
One hundred fifty-nine individuals of six colubrid snake species: Arizona elegans (n = 43, mean snout-vent length [SVL] = 589 mm [+ or -] 205 SD, range = 238-930 mm), Chionactis occipitalis (n = 31, SVL = 258 mm [+ or -] 20 SD, range = 222-300 mm), Masticophis flagellum (n = 12, SVL = 861 mm [+ or -] 118 SD, range 697-1104 mm), Masticophis lateralis (n = 14, SVL = 765 mm [+ or 1] 136 SD, range 520-963 mm), Phyllorhynchus decurtatus (n = 26, SVL = 357 mm [+ or -]47 SD, range = 242-469 mm), and Rhinocheilus lecontei (n = 33, SVL = 590 mm [+ or -] 93 SD, range = 362-743 mm) were borrowed from the herpetology collection of the Natural History Museum of Los Angeles County (LACM), Los Angeles, California (accession numbers, Appendix 1).
This pattern appears common in other colubrid snakes from western North America and has been reported in: Masticophis lateralis
, Masticophis taeniatus, Pituophis catenifer, Arizona elegans, Lampropeltis zonata and Lampropeltis pyromelana (Goldberg 1975; Goldberg & Parker 1975; Aldridge 1979b; Goldberg 1995; Goldberg 1997).
