Abstract

A large number of flies expressing an eye abnormality was observed during the sunmer of 1960 in a "wild" Cockaponsett stock. A review of environmental conditions showed that the temperature had risen to 30 C on several days before the abnormal eyes were detected. Some of the abnormalities resembled certain expressions of known mutants such as lobe and tumorous head. Lobe eyes are reduced and flattened anteriorly, whereas the new abnormal eye is not usually reduced, but is flattened ventrally. The tumorous head phenotype is characterized by abnormal growths in the entire head region, but the new abnormality is usually restricted to the eyes.
