eweifel 108 Aug. 5, 1950 construction, there is a bridge here). Our camp is a few miles past the crossing of the Atchigoga. Aug. 6, 1950 We finally reached Huaroque today at noon, in time to have a fine meal of beans, tortillas, bananas, peas, and jam (?). In the afternoon, Ken and I went down to the arroyo, where we caught a very pretty Thelenota duplex which was chasing an Agalychnis. Later on in the afternoon one of the ninos came up with a small box which we bought for no pay. Aug. 7, 1950 We spent the morning swimming in the arroyo getting a few cichlids, catostomids, and poecilids. The rapidity of color change in the cichlids is amazing. One individual had a bright yellow back and black sides when we seized the same under him, but in the second it took us to lift the net out of the water, the fish had become dull brownish-black all over.
