Th« r«ci itui «// /4# The burrows of the Striped Spermophile are distingiuahed »««. from those of the Yellow species by their smaller size (of barely twoinch calibre instead of three), also they are on the level ground. They usually go straight down for six or seven inches, sometimes much farther, and rarely have any earth mound visible at the door. Apparently the animal is at pains to hide the entrance, so gets rid of the earth- pile by scattering it. Bailey remarks: * " Though many of the burrows open on smooth, bare ground, with nothing to conceal them, the entrances are more commonly hidden by a bunch of grass, and sometimes a dried weed, a piece of papc, or an old rag is drawn over the entrance." They are of at least two kinds. First, a labyrinth of many galleries with many entrances. This is close under the sod, rarely more than three or four inches down. I take it to be a mere playground and refuge; doubtless, also, it serves to mislead such enemies as might be in search of the Ground-squirrel's nest. (Fig. 122). Seco' '', the nesting burrow. This also is a labyrinth, but deeper than the first kind, and it has a large, comfortable chamber about nine inches in diameter, with many approaches, and more than one entrance. This chamber is about six inches down, and is lined with fine, dry grass. At Carberry, September 8, 1904, I dug out the Ground- squirrel nest from which I made the diagram shown in Fig. 123. I did not see the rightful occupant, but suppose from its size and character that it was the work of a Striped-gopher. In one place, as marked, was found a salamander {Ambystoma tigrinum). It was not dormant but very sluggish. Several 'Rep. Pr. GnLSq., i893, p. 3
