For a charming companionship and a patient tolerance of my erratic ways I owe more to Winthrop Sprague Brooks than I can well express. For many years it has been Brooks' good fortune and mine to visit Cuba frequently, and during the War we were there for long periods of many months' duration. Our duties during this time did not permit of much collecting, but constant travelling afforded many chances for observation. On previous and subsequent journeys we have made extensive collections, all of which are now in the Museum of Comparative Zoology, except such specimens as have been distributed in exchange.
