Besides the usual dry-wash- sift-select method, remains of fossil bats were generally singled out before washing in order to keep the teeth in place which otherwise become loose. After individual cleaning and drying again, the fragments were treated with bensolic solution of polystyrol. The measurements were taken with help of a dial caliper or chiefly with an ocular micrometer in a stereo microscope to the nearest 0.01 mm. According to MILLER (1907) and the majority of the authors, e.g. MENU (1985), the dental formula of both subgenera Plecotus and Corynorhinus is -2 3. 1. -2-4567 12 3. 1 - 234567 I chose not to follow HANDLEY (1959) and RABEDER (1974) in their numbering of the upper and lower premolars. The abbreviations used in this work for respective measurements (explanations if necessary are given in parentheses) are as follows. IOB = interorbital breadth CCR = width of rostrum at C-C (at outermost borders of crowns) CCRA = width of rostrum at C-C alveoli (at outermost margins of alveoli) MMR = M3/-M3/width (at outermost points of crowns) MMRA = M3/-M3/ alveolar width (at outermost border of outer alveoli of M3/s) BIN = greatest breadth of intermaxillary notch DIN = depth of intermaxillary notch (from connecting line of foremost tips of praemaxillae to hindermost point of intermaxillary notch) WAPE = greatest width of anterior palatal emargination DAPE = depth of the interior palatal emargination (from connecting line of foremost tips of praemaxillae to deepest point of anterior palatal emargination)
