JESimpson,1938 50+ ft., Punta Peñasca, Sonora. March 31, 1938, continued. at the base at border of lava and sand; set 21 rat-traps in the rocks of hill. Pinned down a lizard with a rock and shot four more in the lava and sand (95-99, inclusive). In response to the excitement of Señor Delgadillo, who set a mouse- trap down in the rocks less than a foot from two rattlesnakes, accompanied him and shot a four-foot rattle- snake (07100) as Señor Delgadillo shot another beside the first (101). April 1, 1938 Caught 2 Perognathus longimembris (07102, 07103) at border of lava in the sand; 2 Perognathus intermedius (07104, 07105; the former very dark pelage; the latter light; taken in consecutive traps 50 ft. apart), 3 Peromyscus eremicus (2 075 and 07106 which was of much lighter pelage than any others taken here by party), 1 Neotoma lepida (07107 which was of light-tan and orange-tan and golden-tan pelage, not the commoner grey pelage of others here and elsewhere). Put up our specimens; I skinned the snakes (partially, leaving anterior and posterior in situ) which Dr. Benson later fried for the piece de resistance (accent the last word) of our lunch; the white meat, tho tough (chawable tho) was very sweet and of excellent flavor. Not to be recommended as a regular part of the diet but well worth trying. [illegible]
