 displaced further inward, so that second triangle is barely half 

 as large as first and conspicuously difierent from it in form.

Meniarhs. — Mijotis rityofis diflers strikingly from the other 

 European members of the genus, M. oxygnatJms excepted, in its 

 much larger size. From the large Vespertilionklse of other genera 

 it is immediately recognizable by its long ears, extending notice- 

 abl}' beyond nostril when laid forward, and by the greyish white 

 colour of the underpiarts. In the MediteiTanean region Myotis 

 myotis is associated with M. oxygnathus ; but it is the only large 

 species known to occur north of the Alps.
