Bats -- Portugal. 16 MISCELLANEOUS PUBLICATIONS MYOTIS MYOTIS (BORKHAUSEN, 1797) Distribution.—M. myotis ranges from the Azores Islands (Palmeirim, 1979) to the Ukraine (Bobrinskii et al., 1965) and from the Mediterra- nean north to Great Britain (Phillips and Blackmore, 1970) and the Baltic Sea (Ruprecht, 1971). In the northern part of its range it seems to be rapidly declining in numbers ( Braaksma, 1970).

Outside Europe it is known only from Asia Minor (£aglar, 1965); Syria, Lebanon, and Israel (Harrison and Lewis, 1961). The records of this species in North Africa and Central Asia actually refer to M. blythii ( Corbet, 1978). Until recently M. myotis has been confused with M. blythii. Thus, older literature records are not reliable and have not been included in the distri- bution map. However, there are enough data to show that the species is common throughout most of the Iberian Peninsula. M. myotis is one of the common cavernicolous species in central and northern Portugal; but it is rare, in the south (Fig. 22). It has not been found in Algarve province in spite of the abundance of caves where the similar M. blythii, a more southerly species, is common. M. myotis is a very gregarious cave-dwelling species, but can also be found roosting in build- ings, bridges, and even trees. Morphology and Taxonomic Remarks.— M. myotis is one of the largest European bats and the largest species of its genus (Table 5). The fur is grayish-brown dorsally, contrasting with whit- ish-gray underparts that often have a buffy tinge. The hair is clearly bicolored, the proximal half the tips on the back. The ears and patagium are being dark slaty-gray and the distal part light brown, varying in tone. The ears are long, but brown or grayish-brown, becoming darker near proportionally much shorter than in M. bech-. Fig. 22. Locality records of Myotis myotis from Portugal. Symbols as in Fig. 9.
