Hendrickson 1950 Cranidophorus lanniscatus Oct. 21 5 km N Villarejo, 1400 ft., Neila, Colombia, S. A. On the sparsely-vegetated S slope of the quebrada S of camp, at about 3:00 P.M., I found 2 individuals in the shade of a small thorn bush. One (the more vividly-colored) was grasping the other (slightly smaller) animal by the back skin just anterior to the pelvic region. The "aggressor" seemed to be oblivious to my attempts to capture the pair. The one being held made strenuous efforts to escape, and successfully evaded me, running back and forth under the bush. They shuttled back and forth thus 5 or 6 times, evading me. At length, I used my gun barrel to "herd" them out onto bare ground; I could not force them out into the hot sun, and eventually, they broke apart and escaped. Oct. 28 Many have been seen since coming to this camp. Paulino is able to snare 10 or more a day near camp if we so wish. Fig. 1 Repeatedly I have seen well-awarded, active, animals run swiftly for a short distance,
