DiHirihidion. — The Blue-bellied Lizard is a northern 

 species, which, coming to us from Oregon, occupies 

 the long coastwise strip of California lying to the west 

 of the Sacramento and San Joaquin Valleys. Close to 

 the coast, its range extends as far south as Ventura 

 County. In the north, its territory stretches eastward 

 at least as far as Mount Shasta and probably extends 

 some distance south in the Sacramento Valley and on 

 the western slope of the Sierra Nevada. Farther south, 

 it crosses the San Joaquin Valley to the western slope 

 of the Sierra Nevada. I have examined specimens from 

 Siskiyou (Sissons, Fort Jones), Mendocino (Fairbanks), 

 Lake (Kelseyville), Sonoma (Healdsburg, Santa Rosa), 

 Napa (Calistoga, Napa, ^Etna Springs), Marin (San 

 Anselmo, Mill Valley), Contra Costa (Mount Diablo, 

 Crockett), Alameda (Oakland, Calaveras Valley, Liver- 

 more, Altemonte), San Francisco, San Mateo (Pesca- 

 dero, La Honda), Santa Clara (Palo Alto, Black Moun- 

 tain, Santa Clara, Los Gatos, Alum Rock Canon, Smith 

 Creek, Canada Valley), Santa Cruz (Soquel), Monterey 

 (Monterey, Pacific Grove, Pleyto), San Benito (Bear 

 Valley, San Benito Valley), San Luis Obispo (San Mi- 

 guel, San Luis Obispo), San Joaquin (Tracy, San 

 Joaquin Bridge), Merced (near Merced), Tuolumne 

 (Big Oak Flat, Groveland to Crocker's, Hodgdon's),
