P. DeBenedictis 1964 10 Feb. Academy Bay, Santa Cruz Island, Galapagos. in the day Bowman managed to cool him off. In the after- noon I got my lumbago back, thank god! Spent some time pulling ticks off the Harboriguanales. The Tropidurus had 8-10 ticks, most of them very large and engaged, and about 95% confined to the auricular and axillary region and with red nits all over, especi- ally in the back, given anal vertebral region. The ticks were very similar to those we later pulled from the Conolophas. The smaller Tropidurus had very few ticks. The land Iguanas had only 1-8 ticks (which is many fewer in proportion to the size of the animal) and then mostly around the vent, singly rather than in the 3's and 4's of the Conolophas. Saw several bob patterns, which show some variations around a theme of 2-3 copse bobs and a bow; sometimes the bobs are given from a head-up, vertically) or head down position, and occ. a bob was given during the bow and pass another or 2 after the bow. The pattern was something like: the set of heads up -> M^up time -> O down . Conputus says this is approximately the reverse of the pattern of An other Conolophas. In the evening went down to Nelson's to get chocolates but he was out. Saw about 20-25 bats here, all apparently the same kind. After dinner they hag a movie scheduled for town but the power failed so this was cancelled. Wrote notes in the evening; rained a little and very windy from the west. Will add a rough map of the Darwin station area [illegible]
