 tagium naked above, furry below; wing membranes naked above, but 

 furred below next to the body and along the border of the forearm.

 faintl}" washed with seal brown on upper side of neck, and with burnt 

 umber across shoulders and on rump. A few brownish-gray hairs are

 neck, and front of chest, where all of the hairs are Idack. Viewed in
