they make a striking- appearance when flying. When in flight, the 
white tips of their wings are conspicuous, although these are hardlj"^

fcetus 65 mm. in length and 218 in extent. Its body, including its 
cars and a portion of its wings, was covered with a very fine mem- 
brane which made it appeal* hairless, but when this meml)rane dried

distinctness of the two can no longer be questioned. The present 
specimens agree perfectly with Dr. Peter's original description. The}^
