Cutamias townsendi -2- Sept 6 Red Mtn., 14 mi. S Hayfork, 5300 ft., Trinity Co., Calif. together, that is, in the same locality but apparently in different habitats. However, in this locality a third species E. sonomae, quite a bit smaller, occupies a habitat intermediate between townsendi and sonomae. E townsendi is not a conspicuous animal, and gives a single "put" note at 2 or 3 second intervals which neither of the other 2 seem to do. As soon as this animal is aware that some one is approaching it shuts up and is thus rarely seen - see accounts of other Eutamias species for comparison. Sept 10 same locality - This species proves to be the only chipmunk present in the mature stands of White Fir-Jeffrey Pine-Incense Cedar forests in which a brushy understory is absent. There it is an animal of fallen logs and upturned roots, and is often seen chasing one another up and down the trunks of the largest forest trees, ascending to considerable heights. It completely plays out when the forest element is left behind as one works onto the high ridges of South Dobabella Mtn.
