Hoffmeister 1939 Citellus lateralis Twin Buttes, 4300 ft., 2 1/2 mi. S.W Steamboat Ints., Skamania Co, Wash. The specimen was a female with the mammary glands highly developed, and was apparently nursing. She was not especially fat but excessively blotted and an examination of the digestive tract showed gaseous blot but little or no waste material. July 12 Caught 2 specimens in 6 rat traps I had set during the day, a short distance from camp. One was an adult and one considerably younger. This species is relatively wary at this locality and difficult to collect by shooting. This area has been burned over and there is not an abundance of fallen logs or bush, but mostly young conifers and tall grass. Consequently, these squirrels most move around a great deal in open grass country, and they thus readily run through the grass & their burrow system and remain hidden for long periods. July 13 Caught 2 C. lateralis in 3 rat traps in about 2 hours time this A.M., in settings in the thicker conifer covering north of camp. The specimens were caught on straight oats bait.
