The tragus is relatively long, is broad at the base, and tapers abruptlyto a pointed tip. Barbastella is a relative of Euderma and Plecotus that lacks the ex-treme auditory specialization characterizing these genera. In thisrespect, Barbastella must be more primitive than Euderma and the other hand, in most cranial details Barbastella is similar toEuderma and Plecotus, and in some features such as fragile zygomata,large anterior nares, posterior nares lying far forward, and short toothrows it has surpassed them in degree of specialization. If the assumption is correct that Barbastella is closely related toEuderma and Plecotus, then it follows that most of the cranial char-acters shared by the three genera must have been established beforeauditory specialization occurred. Further, the Barbastella stock must AMERICAN BATS—^HANDLEY 121 PLECOTUS (CORYNORHINUSl TOWNSENDIIUSNM 148550. PLECOTUS (PLECOTUS) AURITUSUSNM 86667 TRANSVERSERIBS BASAL LOBE
