was found firmly stuck in the roof of a chipmunk's mouth. In 

 August, when the fruits were fully ripe, the purple stain was 

 found to have discolored not only the mouths of the chipmunks. 

 but to have permeated the whole abdominal region internally. 



Citellus tereticaudus chlorus Elliot 

 Palm Springs Ground Squirrel 

 Numerous in a trad of sand dunes on the desert immediately 

 south of the railroad station at Whitewater, 1130 feet. Here. 

 June 3 to 5, eighteen specimens were trapped (nos. 1542 1559 . 

 Three of these are half grown juvenals. Both young and old are 

 distinctly grayer in color dorsally than in series of tereticaudus 

 of corresponding season from the Imperial and Lower Colorado 

 valleys, which are decidedly cinnamomeous in tone. Although we 

 fail to detect any other differences, this peculiarity in color seems 

 to be alone sufficient to warrant the use of the separate name. 

 chlorus, of Elliot (1903, p. 242), type locality Palm Springs. 

 The form is best regarded, in our opinion, as a subspecies of 

 tereticaudus. 



Citellus beecheyi fisheri (C. II. Merriam) 



Fisher ( irouml Squirrel 



Twenty-eight specimens preserved as follows: Whitewater, 

 one (no. 1560); Calie/.on, nine ( nos. 1405-1413); Banning, one 

 (no. 1417 i: Schain's, four (nos. 1635 1637, 2706); Thomas 

 Mountain, one (no. 2217); Strawberry Valley, nine (nos. 2078 

 2086); Tahquitz Valley, two (nos. 2154, 2155); Round Valley, 

 one (no. 1760). The ground squirrel was noted also at 8500 

 feet altitude near the summit of Toro Peak', about Ilemet Lake 

 and through Ilemet Valley, in Deep Canon, and around Asbestos 

 Mountain. In Round Valley, at 9000 feet altitude, it was actu- 

 ally abundant, as also in Strawberry Valley. The species thus 

 ranged from the Pacific to the desert base and from the lowest 

 zone to the highest. It does not occur, however, to the north and 

 east far out on the desert floor, being apparently limited in that 

 direction to the rocky foothills. This is essentially a Pacific dis- 

 trict species, though with remarkable ability to establish itself
