* There is a discrepancy in the numbering of the campaigns between the preliminary reports, where the excavations of first winter are divided into two campaigns, and the final reports where the excavations of winter 1929-30 are reckoned as one season (see Koeppel et al. 1940: vi and North 1961: 1, note 1).
