JESimpson,1938 42. 50'ft., Cerrita Cholla, gmI.wnw Punta Peñasca, Sonora. April 3, 1938, continued. fish, but had no better luck here than we had last night on the camp shore — no fish at all. (Set 50 mouse and 10 rat-traps). April 4, 1938 In traps set along banks of a wash thru the granite rock-hills caught 2 Peromyscus eremicus (♀118, ♀119), one P. cuniculus (♂117), 1 Dipodomys merriami (♂120), and two (juveniles) Neotoma albigula (♀121). This trap-line left out for the day for possible diurnal forms; (the none taken) then taken up and set along sides of rocky hills and in sand; ten additional rat-traps set out (the last-night's rat-line remaining in place). During the day Dr. Benson and I took out the seine-net, repaired it, and, while looking for minnows in the shallows ran down a large sole (small halibut?)(2-2½lbs) which I filleted and fried for dinner—following a clam and oyster chowder (we have had oysters on the half-shell here, but the oysters are small and scarce.) A swim in the warm Gulf water served as both bath and enjoyable relaxation. April 5, 1938 In the granite rocks caught 4 Peromyscus eremicus (♂122; ♀123) and two Neotoma lepida (♂123, ♀124; the ♂ had very light pelage); along bank of wash in the same trap that yesterday took the juvenile wood-rat caught 1 Neotoma albigula (♀125); in the sand and ochotillo 4 Dipodomys merriami (♂122nd, 3 ♀ 3rd). Put up specimens; repaired traps; sought lost traps; set out 50 mouse-traps in sand and sage. Shot
