an animal which has been described under its generic name Vespertilio in the Encyclopaedia. But since that article was written, we have met with an account of a new species, so very singular, that, if the veracity of our author can be depended on, it is well entitled to a place here. This species was discovered in the country of the Nimiquas, in the interior of Africa, by M. Vaillant, during the course of his second travels, and is by him called the oreiller bat. To this title it has indeed a very good claim; for it has, he says, four ears, or at least the external part of four ears, each ear being double; the outer fold, which serves as a covering to the inner, is very ample, being two inches eight lines high, and nearly as broad when stretched out. On the nape also a membrane stands erect, one inch four lines in height, which might be taken for another ear, as it has exactly the shape of one. This membrane, as well as the ears and wings of the animal, are of a rusty red, paler below than above. The body is only three inches long, and is covered with very fine greyish hair. Its width, from the tip of one wing to that of the other, is eight inches. The reader will pardon me, says our author, for inserting these trifling details of measurement, of which I am not more fond than himself; but they appeared to me necessary here, to convey an accurate idea of the extraordinary length of the ears of this animal, which are certainly larger in proportion than those of any other we are acquainted with, since they are only four lines, or the third part of an inch, shorter than the body itself.
