PORTUGUESE BATS 13 the description of mehelyi by Matschie (1901) is ambiguous and may refer to/?, euryale, whereas Cabrera (1904) unequivocally described R. car- petanus. However, the interests of taxonomic stability are served by maintaining the name mehelyi, because it has been used consistently since Miller (1912) ( Corbet, 1978). Family Vespertilionidae Bats of this family are present throughout the temperate and tropical regions of both the New and Old Worlds. About 300 species and 34 genera are included; 18 species of six genera are known from Portugal. In this paper Miniopterus is not included in the Vespertilionidae (see discussion under Miniopteridae). In Europe members of this family can only be confused with the Miniopteridae, but the vesper- tilionids have a baculum, a scapula with an out- wardly curved coracoid, and lack the vestigial anteriormost upper premolar recently found in Miniopterus (Mein and Tupinier, 1977). Key to the Genera of Vespertilionidae Present in Iberia Based on External Characters.— 1. Ear bases joined over top of head; nostrils opening upward 2 1*. Ear bases widely separated; nostrils opening forward 3 2. Ear as long, or almost as long, as forearm (longer than 28 mm); no post-calcarial lobe. Plecotus (p. 35) 2'. Ear much shorter than forearm (shorter than 20 mm); small post-calcarial lobe Barbastella (p. 34) 3. No post-calcarial lobe; pointed tragus (Fig. 15) Myotis (p. 14) 3'. Post-calcarial lobe present; tragus with rounded tip (Fig. 15) 4 4. Tragus mushroom-shaped, wider than high (Fig. 15) Nyctalus (p. 25) 4'. Tragus elongate, higher than wide (Fig. 15). 5 5. Forearm shorter than 38 mm Pipistrellus (p. 28). B Fig. 15. Typical shape of the tragus of A) Myotis, B) Nyctalus, C) Pipistrellus, and D) Eptesicus. 5'. Forearm longer than 45 mm Eptesicus (p. 23) Based on Cranial Characters.— 1. Three pairs of upper premolars Myotis (p. 14) 1'. One o
